Climate Change Regulation 2025 Comparisons

General

Austria is an Annex 1 party to the United Nations Framework Convention on Climate Change (UNFCCC). It ratified the Kyoto Protocol on 31 May 2002 and the Paris Agreement on 5 October 2016.

As a member state of the EU, Austria is part of the climate negotiation group of the EU. As such, Austria does not speak for itself in negotiations.

European Green Deal and Clean Industrial Deal

Fundamentally, it may be noted that Austria’s position in connection with the EU Nationally Determined Contributions for 2030 is that special attention must be paid to the needs of energy-intensive industry, with priority being given to research and further development of green hydrogen. These matters are particularly addressed in the “Clean Industrial Deal”, presented by the European Commission on 26 February 2025.

A draft Industrial Decarbonisation Accelerator Act (IDAA) is undergoing the consultation process until 9 July 2025. The aim of this initiative is to support energy-intensive industries in continuing their decarbonisation efforts while maintaining international competitiveness.

In its 2025–2029 governmental programme the Federal Government of Austria stresses the support of effective implementation and advocates at the EU level for a comprehensive fitness check to assess the cumulative impacts of Green Deal legislation and identify potential goal conflicts.

In addition, global attention must be paid to avoiding uneven competitive conditions as a result of higher EU environmental standards. With regard to the distribution of the reduction burden outside the framework of the EU Emissions Trading System (ETS), Austria rejects the use of the GDP/capita criterion. Austria further considers that special attention must be paid to the criterion of cost efficiency.

Graz Declaration

Under the Austrian Presidency of the Council of the EU in 2018, the Graz Declaration was adopted. Essentially, the Declaration requires the Commission to develop a mobility strategy by 2021 (what it has actually done by drafting the “Sustainable and Smart Mobility Strategy” dated December 2020). Further cornerstones of the Declaration consist, inter alia, of the sharpening of existing CO₂-fleet agreements based on an early review – in line with the necessary decarbonisation path according to the Paris Agreement and the EU Long-term Strategy – to enable a faster transition to electromobility in the area of passenger cars and light and heavy commercial vehicles in particular. Proposals for concrete measures include:

• the rapid introduction of CO₂ limits for buses; and
• the establishment of predictability for the vehicle industry by quickly including reduction paths for the period after 2030.

Initiatives

For the sake of completeness, it is worth mentioning that Austria is represented in several international initiatives connected to climate change, such as “Mission Innovation”, the “Strategic Energy Technology (SET) Plan”, “ERA-Net Smart Grids Plus”, “ERA-Net Smart Cities and Communities”, and “IEA Technology Collaboration Programmes”.

NECP Co-Ordination

Within the framework of the preparation of Austria’s National Energy and Climate Plan (NECP), regional co-operation has taken place with Austria’s neighbouring countries: Germany, the Czech Republic, Slovakia, Hungary, Slovenia, and Italy, as well as with Poland, Croatia, and Belgium. Several of these states met to inform each other about the respective contents of their NECP drafts and to identify possible points of contact for deepened co-operation.

According to the 2025–2029 government programme the current National Energy and Climate Plan (NECP) shall be revised in co-ordination with the Austrian provinces (Bundesländer), in line with the priorities set out in the current government programme.

Pentalateral Energy Forum

Austria is part of the “Pentalateral Energy Forum”, promoting regional co-operation in Central and Western Europe to enhance electricity market integration and security of supply. At the PENTA Directors General Meeting in Vienna in November 2018, it was agreed to use the Forum for future NECP co-ordination. This led to the “Political Declaration of the Pentalateral Energy Forum on Integrated National Energy and Climate Plans”, adopted by energy ministers on 4 March 2019, committing member states to include a joint chapter in their NECPs as a basis for long-term co-operation. This chapter was signed at the PENTA Ministerial Meeting on 25 June 2019.

NECP contents were exchanged and discussed at these events, deepening cross-border interests such as transmission networks and projects of common interest. Common text elements were developed within the Forum and incorporated into Austria’s NECP.

The PENTA states also agreed on cross-border co-operation in renewables, voluntarily working on a package of approaches that includes exploring national or cross-border tenders, joint tenders, leveraging the EU renewable framework, and using existing co-operation forms like joint projects and statistical transfers (“cluster approaches”).

General

In accordance with the requirements stipulated in Regulation (EU) 2018/842, amended by Regulation (EU) 2023/857 establishing binding national annual greenhouse gas emission reduction targets for the period 2021–30 (“Effort Sharing”), Austria is pursuing the goal of reducing its greenhouse gas emissions in non-ETS sectors by 48% by 2030 compared to 2005. During the period 2021–30, a linear target path is to be adhered to in accordance with the above Effort Sharing Regulation.

In line with Austria’s obligations under the Paris Agreement (Section 4, paragraph 12), Austria does not submit its own NDC but is covered by the EU’s collective NDC, submitted in October 2023 to the UNFCCC. The updated EU NDC aims to cut greenhouse gas emissions by at least 55% by 2030 compared to 1990. The next EU NDC is due in September 2025.

Austria submitted its first biennial transparency report under the UNFCCC and Paris Agreement in 2024, concluding that while progress is being made on mitigation and adaptation, substantial further efforts are needed to meet long-term climate targets and integrate adaptation across all sectors and governance levels.

The 2025–2029 Austrian government programme addresses climate change by ensuring efficient, low-bureaucracy implementation of EU climate law. The public sector will act as a “Climate Role Model” by adopting climate-friendly practices, promoting green public procurement, and exploring green lead markets. Austria also reaffirms its rejection of nuclear energy, viewing it as non-renewable, high-risk, and economically unviable.

The Austrian Climate Protection Act, which established sectoral annual greenhouse gas targets through 2020, cites the IPCC’s Fourth Assessment Synthesis Report, emphasising the need to limit warming to 2°C by halving global emissions by 2050 relative to 1990. Austria nominates Austrian scientists, and participates in the IPCC’s seventh assessment cycle (AR7).

Alongside its IPCC involvement, Austria supports national assessments via the Austrian Panel on Climate Change (APCC), set up by the Climate Change Centre Austria (CCCA). The APCC synthesises climate research for Austria, applying global findings to the national context. Its assessments, such as the APCC Assessment Report on Climate Change in Austria 2.0 (AAR2, June 2025), are key to shaping Austria’s climate strategies.

For further information on key policy instruments/measures and initiatives by sector that are intended to contribute to climate change mitigation and adaptation in Austria, refer to 3. National Policy and Legal Regime (Mitigation) and 4. National Policy and Legal Regime (Adaptation).

Financing Measures

The implementation of measures related to climate change is naturally accompanied by a significant investment requirement, which, in line with the long-term targets of the Paris Agreement (in particular Article 2.1.c), must include contributions from the public sector (including the federal government, federal provinces, and the EU) and the private sector in equal measure. The total investment volume ultimately expected to achieve the target is largely determined by the assumed mix of regulatory, subsidy, and tax policy measures.

Austria is in particular focusing on the following topics within the framework of a “Green Finance Agenda”:

• development of new products within existing funding structures (eg, “Exportinvest green”);
• a push for green bonds from government and quasi-government issuers;
• a review of the legal framework to create incentives for green or sustainable financial products;
• modernising covered bond legislation to enable green or sustainable covered bond issuance;
• reviewing how existing portfolio analysis tools (eg, PACTA) may be used in the Austrian market; and
• establishing initiatives to get companies to join forces on a common strategy of green and sustainable investment policies.

Technology Transfer

The successful positioning of Austrian energy technology providers requires, on the one hand, the active networking and co-operation of Austrian players in international research, technology, and innovation (RTI) initiatives (such as the strategic energy technology (SET) Plan of the EU or the co-operation programmes of the International Energy Agency) and, on the other hand, the strategic bundling of individual strengths into comprehensive solution offerings.

Loss and Damage

In Austria, natural hazard management is carried out highly efficiently thanks to many years of experience and practice, which is why the population’s sense of security is very strong. However, established natural hazard management is primarily concerned with risk reduction, based on historical reference values and past events.

In the future, at least soft adaptation limits may be expected at the local level in Austria. The doctrine demands that these possible limits to adaptation – with the material and non-material losses and damages that potentially accompany them – should be proactively addressed in the development of climate change adaptation strategies by the federal states (Bundesländer). Moreover, it will require not only a transformation of risk governance toward comprehensive climate risk management, but also transformative individual measures in adaptation that will go far beyond the current, mainly structural, public-sector measures (eg, planned relocation of communities or individual settlements, new livelihoods for individuals and households, nature-based solutions, and private insurance models that also stimulate self-provisioning).

The 2025–2029 government programme states that more frequent extreme weather demands stronger protection, especially for floods and forests. Natural areas will be made more resilient through climate-adapted forests, green space preservation, and heat-tolerant trees. Infrastructure will be adjusted by planning and construction to address flood and storm risks, supported by suitable regulations to secure land for protective measures.

Carbon Capture Utilisation and Storage (CCUS)

According to the current legal situation under EU law and Austrian law, cross-border CO₂ transport for geological storage under the seabed from Austria to other contracting states of the European Economic Area is permitted. In this respect, Austria fulfils its legal obligations arising from international treaties and EU law. However, Austria is a landlocked country, and the geological storage of CO₂ in Austria is prohibited – with an exception for research purposes with a planned total storage volume of less than 100,000 tonnes. Therefore, CO₂ that is captured from industrial or energy facilities for the purpose of geological storage would have to be transported across borders to other contracting states of the European Economic Area (EEA) that have geological CO₂ storage fields, according to the current legal situation.

However, it should be noted that according to the government programme for 2025–2029, the ban on geological CO₂ storage in Austria will be lifted. This represents a significant shift in national climate and energy policy and builds upon the Carbon Management Strategy issued in June 2024.

General

Austria is a federal state with a constitution that divides legislative responsibilities between the federal government and the federal states, sometimes creating shared competencies. For example, in many areas, including energy law, the federal level sets basic laws while the states handle implementation.

Climate policy in Austria is a typical cross-cutting issue, particularly regarding the distribution of responsibilities for emission reduction and climate adaptation measures.

State Goals of Environmental Protection and Sustainability

The constitutional basis for Austria’s climate protection policy lies in the commitment to comprehensive environmental protection (Bekenntnis zum umfassenden Umweltschutz). It was introduced in 1984 with the Federal Constitutional Law on Environmental Protection (BVG Umweltschutz) and is now anchored in the Federal Constitutional Law on Sustainability (BVG Nachhaltigkeit).

Under the Federal Constitutional Law on Sustainability, Austria (through the federal, state, and municipal levels) is committed to comprehensive environmental protection. It defines this as safeguarding the natural environment from harmful effects, especially by keeping air, water, and soil clean and reducing noise. The authors interpret this to include climate protection, since the term “comprehensive environmental protection” is used and the list in Section 3, paragraph 2 of the Act is merely illustrative. Section 3 is a “state objective provision” (Staatszielbestimmung), meaning it mandates state action but does not grant individuals enforceable rights.

The state objective provision is very generally worded, leaving broad scope for interpretation. As a result, only laws that grossly violate the state objective of environmental protection risk being unconstitutional.

Moreover, environmental protection is not among the foundational laws of the Austrian Constitution, so it does not create an absolute priority for environmental interests. According to Constitutional Court case law, its main role is to establish a public interest that must be considered in balancing interests. Thus, the state objective can justify restrictions on the freedom of acquisition. However, the Constitutional Court, in line with legal doctrine, holds that this objective is subordinate to fundamental rights, meaning legislation and administration must uphold equality before the law even when pursuing environmental goals.

Climate protection as a state objective provision is also included in six (out of nine) federal state constitutions – however, its effect is limited to implementation within the sphere of influence of the federal states. In addition, the above applies. Also, at the level of simple (federal) legislation, Section 4 of the Renewable Energy Expansion Act (EAG) reflects the Austrian legislator’s commitment to achieving climate neutrality in Austria by 2040. This goal is to be realised in particular through the measures set out in the Act (see also 8.1 Renewable Energy for further details on the EAG).

Climate Change Act 2011

Climate change issues are formally regulated in the Climate Change Act (Klimaschutzgesetz – KSG), which was enacted in 2011 and last amended in 2017. This federal Act which, in the hierarchy (Stufenbau) of the Austrian legal system, is to be qualified as a simple (federal) law, defined emission caps for the following sectors for the periods 2008–12 and (after the 2017 amendment) 2013–20:

• energy and industry (outside the EU–ETS);
• transport;
• buildings;
• agriculture;
• waste management; and
• fluorinated gases.

The KSG requires the federal government and states to develop measures to meet sector targets and agree on cost-sharing if Austria exceeds its annual emission caps. It also created the National Climate Protection Committee (NKK), comprising representatives from politics, administration, science, business, and civil society, to discuss key climate policy issues under the Paris Agreement. Since the KSG has not been amended after 2017, no legal emission caps exist beyond 2020.

At EU level, new NDCs were submitted in October 2023. Regulation (EU) 2023/857 sets a 40% emission reduction by 2030 (from 2005 levels) for covered sectors. Austria’s target is a 48% reduction, up from 36% under the original NDC. Austria also commits to specific net emissions and removals for 2026–2029, aiming for -879 Kt CO₂eq by 2030 compared to 2016–2018. Additionally, the government plans to achieve climate neutrality by 2040.

A draft of a new climate protection law is currently under government debate and has not yet been released to the public.

Federal Energy Efficiency Act

The aim of the Federal Energy Efficiency Act (Bundes-Energieeffizienzgesetz – EEffG) is to improve energy efficiency by setting energy-saving measures. The law was promulgated as part of the federal government’s energy efficiency package in August 2014 and came into force on 1 January 2015. It transposes EU Directive 2012/27/EU on energy efficiency into Austrian law. The Federal Energy Efficiency was amended by means of Federal Law Gazette I No 68/2020. On 1 February 2023, the government approved the new Federal Energy Efficiency Act 2023 (Bundes-Energieeffizienzgesetz 2023 – EEffG 2023). The new Federal Energy Efficiency Act 2023 entered into force on 15 June 2023 and was partially amended in April 2024.

Emission Allowance Act 2011

Finally, the Emission Allowance Act 2011 (Emissionszertifikategesetz – EZG) should also be mentioned as a central law which may be assigned to climate change law, since it creates a system for trading greenhouse gas emissions allowances, thereby reducing greenhouse gas emissions in a cost-effective and economically efficient manner.

In time for the start of the fourth period of EU emissions trading on 1 January 2021, an amendment to the EZG came into force on 22 December 2020. The most recent amendment to the EZG came into effect on 1 January 2024. The amendment transposes the revision of the EU Emissions Trading Directive and the EU Regulation for the establishment of a CO₂ border adjustment mechanism into national law. In addition to the ETS-1, a second trading system (ETS-2) is introduced for emissions from the building sector, road transport, and small emitting industries. The certificates of ETS-2 will be auctioned, with additional market stabilisation reserves and rules provided. For the administration of ETS-2, requirements for application, approval, and reporting obligations must be met, as well as the submission of the annual certificates for the allocated certificates for the previous year.

In addition, the CBAM-Enforcement Act 2023 (CBAM-Vollzugsgesetz 2023 – CBAM-VG 2023) regulates the reduction of the free allocation of emission certificates starting from 2026 for those sectors that produce goods which, upon import from third countries, are subject to Regulation (EU) 2023/956 establishing a CO₂ border adjustment mechanism, and for which a separate CBAM factor was introduced in Article 10a(1a) of the ETS Directive. The CBAM will be progressively established and become fully effective by 2034. The responsible authority is the Customs Office of Austria (Zollamt).

Claims for free allocation of emissions allowances may be made for two five-year periods each (2021–25 and 2026–30) pursuant to Section 24b, with applications for the 2026–30 period to be submitted by 30 May 2024 pursuant to Section 13a of the Allocation Rules Ordinance (Zuteilungsregelverordnung). For the fourth period of EU emissions trading, the EZG now provides that a report on the annual activity rate together with a verification report must be submitted annually by 31 March at the latest for installations for which an application for free allocation of emissions allowances has been submitted.

If the current activity data shows that an adjustment to the allocation is necessary, then the changes are notified to the European Commission by 30 April. After acceptance of the decision by the European Commission, the change in allocation is made by notice (Bescheid) and the difference is either booked additionally or returned by the plant operator.

Austria has not concluded/ratified any bilateral or multilateral agreements with other parties to the Paris Agreement regarding the implementation of climate protection measures.

Federal Ministry for Climate Action, Environment, Energy, Mobility, Innovation, and Technology

The key policy and administrative authority responsible for climate change policy development and regulatory enforcement is the Federal Ministry of Innovation, Mobility and Infrastructure (BMIMI). The BMIMI therefore plays a co-ordinating role in climate policy at the national level. In this sense, strategy processes are also steered by the BMIMI (if necessary, together with other ministries). In particular, the BMIMI is primarily responsible for the draft amendment and enforcement of the KSG, the enforcement of the EZG, and the EAG (see also 8.1 Renewable Energy).

Climate and Energy Fund

With its funding and initiatives, the Climate and Energy Fund supports the federal government in implementing the climate and energy targets set out in the NECP, drives the energy and mobility transition in Austria with its programmes, and raises public awareness. In concrete terms, a total of EUR3.7 billion in funding has flowed into the domestic economy through the Climate and Energy Fund from 2007 until 2024. Around 400,000 realised projects have thus triggered an average of around six times that amount in investments. It is the only federal instrument that may access all funding instruments (research funding and environmental funding), since the fund uses different processing agencies. Furthermore, the Climate and Energy Fund is the only instrument that focuses on the topics of energy, mobility, and heat transition as well as climate change and adaptation, and thus works exclusively thematically, and not along funding guidelines.

Climate Council

The Climate Council was founded as a result of the climate referendum in June 2020. According to the resolution of the National Council, the Climate Council is to be established as a participatory process for the discussion and elaboration of concrete proposals for the climate protection measures necessary to achieve the targets on the way to climate neutrality in 2040.

The members of the Climate Council are supported by scientists from various disciplines who contribute information on the current state of research.

Environmental Agency Austria

As Austria’s most important environmental expert organisation and one of Europe’s leading environmental consultants, the Environmental Agency Austria (Umweltbundesamt, EAA) advocates for the transformation of the economy and society to ensure sustainable living. Its experts provide the basis for decision making at local, regional and international levels. The EAA engages in dialogue with politics, administration, business, science, and civil society.

Austrian Energy Agency

The Austrian Energy Agency provides solutions for climate-neutrality by focusing on new technologies, efficiency, and the use of natural resources such as the sun, water, wind and forests. The Agency provides scientific advice to politicians, businesses, administrations and international organisations.

The Austrian Energy Agency also implements the climate protection initiative klimaaktiv (for further discussion, see 4. National Policy and Legal Regime (Adaptation)) on behalf of the federal government, and performs the tasks of the National Energy Efficiency Monitoring Agency. The federal government, all federal states, major companies in the energy and transport industries, interest groups, and scientific organisations are members of the Agency.

Provincial Governor

The provincial governor (Landeshauptmann) is responsible for issuing the permits for the emission of greenhouse gases pursuant to the current EZG, namely insofar as the permit most essential for the operation of the installation in question is a permit pursuant to provincial regulations (German: “landesrechtliche Vorschriften”). In all other cases, the authority responsible for issuing the permit is the authority responsible under the federal administrative regulations for approving those parts of the installation from which the emissions originate. The provincial governor, as the competent authority, may also entrust the district administrative authority (Bezirksverwaltungsbehörde) with the implementation of one or more procedures for certain types of installations, and authorise the authority to decide on their behalf.

Austria has not yet seen the volume or intensity of climate change litigation found in countries like the Netherlands or Germany. However, climate litigation has emerged as a tool in Austria, mainly through strategic cases aimed at strengthening climate policy.

Unlike other countries, climate change litigation in Austria does not occur through civil lawsuits but primarily through administrative proceedings. These typically involve Environmental Impact Assessment (EIA) procedures, where environmental organisations invoke environmental and constitutional rights.

A landmark case is the “Third Runway Verdict” by the Austrian Constitutional Court (VfGH), which found that the appellate court had grossly misjudged the legal situation by giving excessive weight to environmental and climate protection interests in its decision, which is not stipulated in the Austrian Aviation Act.

Recently, individuals have increasingly invoked Articles 2 and 8 of the European Convention on Human Rights (right to life and respect for private and family life, including physical integrity) before the VfGH, arguing the state must protect against climate change. However, all such applications have failed due to the Court’s strict admissibility rules.

In another case, an environmental organisation sought a regulation under the Austrian Trade Regulation Act (GewO) to ban or restrict fossil fuel and heating oil sales. The VfGH rejected this, citing the legislature’s wide discretion in fulfilling protective duties, finding no fundamental rights violation.

In summary, climate litigation in Austria plays little role in civil proceedings but is gaining importance in administrative cases, partly due to stronger procedural rights of environmental organisations under Article 9 of the Aarhus Convention and Article 47 of the EU Charter of Fundamental Rights. For example, in a decision on 22 May 2025, the Austrian Supreme Administrative Court (VwGH) ruled that recognised environmental organisations can demand compliance with nature impact assessment requirements under the Lower Austrian Nature Conservation Act.

The following is a summary of the key instruments/measures and initiatives by sector/topic that are intended to contribute to climate change mitigation in Austria.

Traffic Sector

Traffic accounts for about 28% of Austria’s total emissions, making it the second highest emitting sector. To meet the 2030 target, emissions are to be cut by around 7.9 million tonnes CO₂eq, from 23.6 million tonnes in 2017 to about 15.7 million tonnes. Austria’s strategy for low-emission mobility follows the principles of “avoiding” unnecessary transport, “shifting” to efficient modes, and “improving” technologies.

Key measures include strengthening and expanding public transport (with electrification and mobility management), boosting walking and cycling, shifting freight from road to rail, and promoting e-mobility. Implementation tools involve adapting public procurement (eg, converting fleets to zero- or low-emission vehicles), expanding infrastructure, granting targeted subsidies, phasing out harmful incentives, and raising awareness.

Building Sector

There is also great reduction potential in the Austrian building sector, especially through thermal refurbishment, which provides an important economic impetus for domestic industry, by abandoning fossil fuels in new construction and switching to renewable energy sources and highly efficient district heating in existing buildings. Currently, the building sector has a share of 10% of the total emissions. This way, emissions may be reduced by around three million tonnes of CO₂eq to around five million tonnes of CO₂eq by 2030 in a socially and economically compatible manner.

To implement this measure, the Renewable Heat Act (Erneuerbare-Wärme-Gesetz, EWG) has entered into force in February 2024. It generally prohibits the installation of heat supply systems based on fossil fuels for space heating and/or hot water preparation in new building construction (with corresponding transitional provisions for projects under construction). For fossil fuel-operated installations in existing buildings, no regulations are made in the EWG.

Energy and Industry Sector Including Emission Trading

The energy and industry sector is currently Austria’s main contributor to carbon emissions and has a share of around 45%. Austria’s aim is to trigger a surge in innovation by promoting energy efficiency measures and the broadest possible switch to renewable energy sources or electricity-based processes. For example, with the Electricity Industry Act (ElWG), which entered the public consultation process on 4 July 2025, a significant step towards this goal has been taken by promoting, among other measures, the decentralisation of renewable energy production and the storage of energy via Battery Energy Storage Systems (BESS), provided that the act is adopted with the necessary quorum by the Austrian National Council after the four-week consultation period has concluded.

Agriculture Sector

In the area of agricultural production, greenhouse gas (in particular methane and nitrous oxide) reductions shall be realised, inter alia, through measures in the animal sector (fertiliser management, feeding strategies, and husbandry systems), soil cultivation (humus build-up (humus being organic matter in soil) and stabilisation/carbon storage, and erosion control), and through the preservation of permanent grassland, productive arable land, and wetlands.

Furthermore, measures to increase renewable energy production and use (Agri-PV, agricultural biogas plants, waste heat recovery, renewable fuels, and engine retrofits) were put in place to increase farm energy efficiency.

Waste Management Sector

While a clear downward trend was recorded for landfilling due to the ban on depositing untreated waste with high organic content, which has been in force since 2004 and 2009 respectively, emissions from the other recovery and treatment routes, especially from waste incineration, increased.

Austria’s aim is thus to avoid methane- and CO₂-emissions, in particular through waste avoidance, aerobic and anaerobic treatment of biogenic waste, reduction of single-use plastic articles and the increase in the recycling share of municipal waste.

Apart from awareness raising and the identification and gradual elimination of counter-productive incentives and subsidies, no specific instruments for achieving these goals have yet been presented by the Austrian legislator in this regard.

However, according to Austria’s current government programme the Waste Management Act (AWG) is being evaluated with the aim of optimising processes and increasing procedural efficiency.

Renewable Energy Sources

By 2030, Austria plans to increase the share of renewable energy in its gross final energy consumption to 46–50% and to cover 100% of electricity consumption from renewables. This aim is to be achieved, in particular, through the expansion of renewable energy generation under the EAG, which came into force on 28 July 2021 (original version) (see also 8.1 Renewable Energy). The implementation of framework conditions includes feeding biogas and renewable hydrogen into the existing natural gas infrastructure, the development of a hydrogen strategy, and support for future investments in the hydrocarbon industry that are close to the industry (subsidy interest rates).

For this purpose, operating subsidies are provided in the form of sliding market premiums as well as investment subsidies. In addition, biogas and hydrogen benefit from more favourable taxation due to their allocation to the Natural Gas Tax Act (Erdgasabgabegesetz).

In the 2025–2029 government programme, the Austrian Federal Government commits to enacting a climate law that creates the regulatory framework for measures, tools and governance to achieve climate targets and climate neutrality, climate change adaptation and the circular economy. The revised KSG shall contain binding annual caps for total national emissions. Among other elements, it is intended to establish and regulate the tasks of a climate governance structure, introduce climate checks within impact-oriented assessments, define the process for the National Climate and Energy Plan (NECP), and set out the framework for climate-neutral administration.

It shall establish and regulate the responsibilities of an interministerial steering group and define a correction mechanism to be triggered if the binding annual emission caps are exceeded. The focus is intended to be on overall responsibility and flexibility across sectors.

The steering group shall be responsible for developing a climate roadmap that serves as a planning tool and includes both monitoring and indicative reduction pathways or greenhouse gas budgets for each sector, which are to be compared with projected emission trends.

In line with the goal of climate neutrality by 2040, the climate roadmap is also expected to outline the measures taken by the federal government and the federal states. The involvement of federal states and municipalities, social partners, and civil society shall be ensured, and a scientific advisory board shall be established.

Requirement to Report Greenhouse Gas Emissions

In accordance with Section 9 of the EZG, plant owners and aircraft operators participating in the EU–ETS must submit an annual emissions report verified by independent experts to the BMIMI by 31 March of the following year at the latest. The confirmation of the verified emissions in the emissions trading registry must be carried out by the same deadline. A certificate must be submitted for each metric ton of CO₂eq emitted.

The “EDM application”, which is an interconnected system of internet applications and databases to support complex processes for environmental protection-related documentation, notification, and reporting obligations, is used to record and report greenhouse gas emissions from stationary installations, as well as emissions and tonne-kilometres from aviation activities in accordance with the EZG. The EDM system implements the reporting submission process (facility owner/aircraft operator – independent verifier – authority).

The emissions trading registry, in which the allocation, holding, and surrender of allowances are carried out, is a completely independent system.

Facility owners and aircraft operators who are uncertain whether they fall within the scope of the EZG are invited to submit an inquiry in this regard to Department VI/1 of the BMK.

Emission monitoring shall be carried out in accordance with the relevant legal basis, namely for:

• installations – monitoring of emissions shall be carried out in accordance with the relevant Austrian and EU legal requirements, the permit pursuant to Section 4 of the EZG, and the associated monitoring concept; and
• for aircraft operators – monitoring of emissions shall be carried out in accordance with the relevant EU legal requirements and the monitoring concept approved pursuant to Section 8, paragraph 2 of the EZG.

Taxes (Special Expenses – “Sonderausgaben”)

Private expenses for the thermal renovation of buildings or for the replacement of a heating system based on fossil fuels with a climate-friendly system (eg, district heating) may be deducted as special expenses as of 2022 under certain conditions (eg, receipt of a federal subsidy; expenses less subsidy exceed the amount of EUR4,000 or EUR2,000 depending on the specific expense – ie, thermal renovation or replacement of a heating system). In this context, the actual expenses distributed over five calendar years are to be automatically taken into account by a lump sum. The lump sum for thermal renovation is therefore to be EUR800/year and the lump sum for the replacement of a heating system is EUR400/year.

Taxes (CO₂ Tax – CO₂-Steuer/Bepreisung)

From October 2022, CO₂ emissions are to cost EUR30 per tonne. The level of the CO₂ tax will, as in Germany, increase year by year (in 2023 it will amount to EUR35 and in 2024 to EUR45) and gradually rise to EUR55 per tonne by 2025.

However, in the event of significant changes in energy prices, a so-called price stability mechanism (Preisstabilitätsmechanismus) may also lead to a slower or faster increase in the CO₂ tax.

For consumers, this new tax will have a significant impact on heating and fuel costs. According to calculations by the economic research institute (Wirtschaftsforschungsinstitut – WIFO), the introduction of the CO₂ tax will result in a price increase of 7.7 cents (including VAT) per litre of gasoline and 8.8 cents (including VAT) per litre of diesel. For natural gas, the price will rise by 7.3 cents (including VAT) per m³ and a price increase of 9.7 cents (including VAT) is expected for heating oil.

Taxes (Greening of the Standard Consumption Levy – Ökologisierung der Normverbrauchsabgabe)

The calculation of the standard consumption levy (NoVA) for cars is based on the CO₂ emission value in g/km according to WLTP minus 112g (2021). This value is to be divided by five. The commercially rounded result is the tax rate used to calculate the NoVA. The maximum tax rate is 50%.

If a car has CO₂ emissions exceeding 200g/km, the tax for the CO₂ emissions exceeding the limit of 200g/km is increased by EUR50 per g/km. The tax amount is to be reduced by a deduction of EUR350.

In the years 2022–24, these values shall be adjusted annually:

• the CO₂ deduction amount shall be reduced annually by the value of five;
• the malus threshold shall be reduced annually by the value of 15;
• the malus amount is increased annually by the value of ten; or
• the maximum tax rate is increased annually by 10%.

Beginning 1 January 2025, only the CO₂ deduction amount will be reduced annually by the value of three.

The respective law has been recently amended, based on the government programme for 2025–2029: The scope of application of NoVA is to be limited to motor vehicles used for passenger transport. As a targeted locational policy measure to strengthen Austria as a business location, motor vehicles primarily intended for goods transport will no longer be subject to NoVA.

Climate and Energy Model Regions – Klima- und Energie-Modellregionen

Beyond municipalities, the Climate and Energy Model Regions programme of the Climate and Energy Fund supports regions in making optimal use of their local renewable energy resources, in exploiting the potential for energy savings and in sustainable management, and further promotes co-operation between municipalities.

Tailor-made investment subsidies are available for climate and energy model regions from the Austrian Environmental Fund and the Climate Fund. This has resulted in over 7,000 successful projects to date, for example in the areas of renewable energy, energy efficiency, sustainable mobility and awareness raising. There are currently 130 climate and energy model regions in 1,177 municipalities in Austria.

The following is a summary of the key instruments/measures and initiatives by sector that are intended to contribute to climate change adaptation in Austria.

The Austrian Strategy for Adaptation to Climate Change – Die österreichische Strategie zur Anpassung an den Klimawandel

Adaptation to climate change is set against climate protection as an equally important goal. Austria has been pursuing this two-pillar principle in climate policy for some years now, focusing, on one hand, on reducing GHG emissions to directly mitigate climate change, and, on the other hand, on adapting to those effects of climate change that may no longer be avoided.

Since 2012, Austria has had a strategy for adapting to climate change compiled by the (then) Federal Ministry for Sustainability and Tourism, consisting of 132 concrete recommendations for action for adjustment of a total of 14 fields. The latest version was adopted by the Council of Ministers in April 2024.

In its 2025–2029 programme, the Austrian Federal Government highlights that insights from existing climate change adaptation model regions (KLAR!) and climate and energy model regions guide future priority measures. The programme outlines climate adaptation steps, including:

• increasing the binding force and implementation of Austria’s National Climate Change Adaptation Strategy with stronger institutional support;
• developing nationwide strategies to address more frequent and intense extreme weather;
• establishing a scientific and technical Task Force “Climate Change Adaptation – Future-Proof Austria” to advise the government;
• enhancing ecological and technical flood protection and safeguarding protective forests;
• promoting nature-based resilience through climate-resilient forests, green spaces, and heat-tolerant urban trees;
• adapting infrastructure and spatial planning to increased flood and storm risks;
• facilitating land provision for natural hazard protection via suitable regulations;
• offering free, user-friendly regional and local climate risk assessments and hazard maps, especially for municipalities; and
• strengthening European co-operation and knowledge exchange in line with rapid implementation of the EU Climate Change Adaptation Strategy.

Climate Change Adaptation Model Regions (Klimawandel-Anpassungsmodellregionen) – KLAR!

Against the background of the increasing impact of climate change on Austrian regions and municipalities (of course, depending on the specific geographical, geological, and socio-economic framework conditions), the Climate and Energy Fund in co-operation with the BMIMI (then Federal Ministry for Climate Action, Environment, Energy, Mobility, Innovation, and Technology (BMK)) initiated the Climate Change Adaptation Model Regions (KLAR!) funding programme in the autumn of 2016.

The aim of the programme is to give regions and municipalities the opportunity to prepare for climate change, to minimise the negative consequences of climate change by means of adaptation measures and to take advantage of the opportunities that arise. Through the KLAR! service platform and the KLAR! events, the Climate and Energy Fund ensures that the KLAR! regions use the available findings and information delivered by science.

The already existing Climate and Energy Fund supports these efforts through a two-stage programme, as set out below.

• Concept and implementation phase:
1. preparation of a regional adaptation concept (one year);
2. review and approval of the concept by an external jury; and
3. after jury approval, implementation of measures as foreseen in the regional adaptation concept (two years).
• Continuation phase – continuation, adaptation, and dissemination of measures, activities, and processes.

Currently, 93 KLAR! model regions from all over Austria are working on adaptation to climate change. As of now, new regions may apply for support in KLAR!. In addition, existing regions may submit for implementation and continuation. The last call for proposals for KLAR! regions ran from Summer 2024 until the end of January 2025. The next call for proposals is expected in Summer 2025.

Climate protection initiative – klimaaktiv

klimaaktiv is the climate protection initiative of the BMIMI (formerly BMK). By developing quality standards, training professionals, transferring “green skills” to key multipliers, offering consulting and information, and leveraging a large partner network, it complements climate funding and regulations.

Its focus areas include construction and renovation, energy saving, renewables, and mobility. Essentially, klimaaktiv is an innovative governance tool that integrates ideas, strengths, and commitment from Austria’s states, municipalities, businesses, and NGOs, reinforcing them at the federal level.

It also promotes new technologies by equipping stakeholders with the knowledge to apply the latest energy efficiency and renewable solutions. The Austrian Energy Agency (see 2.4 Key Policy/Regulatory Authorities) manages klimaaktiv’s programmes and projects.

Climate change adaptation in the context of environmental permits/authorisations

For further information on this topic, refer to 6.2 Directors’ Climate Change Liability.

Austria is part of the European Union and thus takes part in the European Union Emissions Trading Scheme.

On 2 May 2022, the Office for National Emissions Trading (AnEH) was integrated as an independent entity into the Austrian Customs Office. It takes the role of the Designated National Authority (DNA). The AnEH currently consists of three units: the specialist department and two teams. The task of the AnEH and its employees is to implement the National Emissions Trading Act (NEHG) 2022 and its associated regulations (NEHG Implementation Regulation 2022 and NEHG-EU-ETS Exemption Regulation). The focus for the employees is on supporting companies and organisations with inquiries, reviewing applications and declarations, and co-developing the organisational unit AnEH. Furthermore, in Austria, the Office for National Emissions Trading (AnEH) within the Austrian Customs Office is responsible for handling the Carbon Border Adjustment Mechanism (CBAM) and thus serves as the central contact point. It has established the National Emissions Certificates Information System (NEIS). In the future, the AnEH will play a crucial role in monitoring and managing emissions trading and ensuring that the law can unfold effectively and powerfully. It will contribute to Austria fulfilling its obligations in the area of climate protection and reducing greenhouse gas emissions. Overall, the integration of the AnEH into the Austrian Customs Office is an important step towards the effective implementation of environmental and climate protection measures.

Carbon market-related information is publicly available and updated regularly. Both the Environmental Agency Austria (Umweltbundesamt) and the Federal Ministry of Innovation, Mobility and Infrastructure (BMIMI) provide information on carbon markets.

The planned reduction in the free allocation of emission allowances in the context of the introduction of CBAM is expected to result in higher prices for fertilisers, cement, steel, iron, power, and aluminium. This not only results in a direct cost burden for the aforementioned primarily affected goods, but also an indirect additional burden for the associated supply chains and thus other sectors of the economy, such as the automotive industry, the chemical industry, the electrical and electronics industry, and the construction and food industries. A study by the Austrian Institute of Industrial Research (Industriewissenschaftliches Institut – IWI) concluded that an end to free allocation in 2035 would require a total of 12.1 million tonnes of additional allowances for emissions. Assuming an allowance price of EUR90 per tonne for the goods affected under the CBAM, this would result in additional direct costs of EUR1.1 billion. Furthermore, the indirect additional costs would amount to EUR529.4 million in 2035; in total, the direct and indirect additional costs would thus amount to EUR1.62 billion. In the years 2026 to 2035, a total of up to EUR8.9 billion in direct and indirect additional costs could be incurred in the Austrian economy.

The Austrian stakeholders therefore demand that the free allocation of emission allowances must remain in full force until there is proof of the effectiveness of the CBAM as a protection against carbon leakage. CBAM has been implemented into national law by the CBAM-Enforcement Act 2023 (CBAM-Vollzugsgesetz 2023 – CBAM-VG 2023). See 2.2 National Climate Change Legal Regime.

In 2019, the BMIMI (then BMK) and the Federal Ministry of Finance (BMF) launched a stakeholder dialogue process to develop Austria’s green finance agenda. This led to the creation of the Green Finance Alliance (the “GF-Alliance”), which focuses on aligning the financial sector with science-based climate and environmental targets, as another initiative that will pave the way for a sustainable financial system.

The GF-Alliance helps participating financial companies with these tasks and provides support for financial companies that have committed in writing to setting targets and implementing measures for their portfolio. By establishing the GF-Alliance, the BMF has created an alliance of financial companies that want to systematically align their core business with climate targets.

With the professional and technical support of the Environment Agency Austria and international experts, these companies will become visible role models and trailblazers for sustainable business that is compatible with climate protection. The GF-Alliance has also been influenced, among others, by the Task Force on Climate-related Financial Disclosures (TCFD). The final recommendations of the TCFD are one of the guidelines the GF-Alliance members should align their reporting with.

Under Austrian tort law there is no personal liability of directors for the climate change impacts on their companies or of their companies. The Austrian Environmental Liability Act (Bundes-Umwelthaftungsgesetz) only stipulates a liability for damages to the soil and to water but does not allow for a general liability for climate change.

Infrastructure investments or financing arrangements that may have a negative climate change impact are not the target of any regulatory attention. However, the infrastructure project itself must undergo an environmental impact assessment (Umweltverträglichkeitsprüfung). According to the Austrian Environmental Impact Assessment Act 2000 (Umweltverträglichkeitsprüfungsgesetz 2000 – UVP-G 2000) an environmental impact declaration must be submitted to the authorities. This declaration also contains a climate and energy concept, which must describe all measures that are taken to mitigate the climate change impact of the infrastructure project. The environmental impact assessment is a requirement to obtain the permits for the infrastructure project. The assessment may also be requested by interest groups and civil society and thus gets broader attention in Austria.

Since there is no liability of the company or the director for climate change damage under Austrian tort law, there is also no liability for shareholders or a parent company. Moreover, the Austrian Environmental Liability Act does not foresee a direct liability for shareholders or a parent company for any damages to the soil or water. However, under the “polluter pays” principle of the Austrian Environmental Liability Act, the company or the operator of a facility is liable for the damages and must take compensating measures. The costs for the compensating measures are borne by the polluter.

Under current Austrian law only very big corporations (ie, those with over 500 employees), which are of public interest, are required to file a “non-financial” declaration (ESG report) within their annual report. Currently, this only applies to about 120 companies in Austria. However, according to the EU Corporate Sustainability Reporting Directive (CSRD), which entered into force on 5 January 2023, and must be transposed into national law in Austria until 6 June 2024, ESG reporting will become mandatory for large, limited liability companies (GmbH, those with more than 250 employees and EUR40 million in turnover), stock companies, companies listed on the stock market in an EU member state, and capital-market oriented corporations. Starting from 2026, ESG reporting will also be mandatory for SMEs. Until now no draft national implementation legislation has been published or adopted.

However, the EU’s Omnibus Simplification Package, proposed by the European Commission on 26 February 2025 and partially adopted by the European Parliament and Council in April 2025, postpones and simplifies CSRD implementation. Planned simplification measures also apply to CBAM (see 5.2 European Union Carbon Border Adjustment Mechanism (CBAM)).

In the past, only environmental due diligence was part of a transaction. However, over the last decade climate change and ESG in general have become a more important topic in due diligence. The focus shifted from only checking for potential environmental liabilities to checking what measures a company has in place to protect the climate or mitigate its impact on the environment. Although this is a rather new part of the due diligence process in Austria, M&A attorneys are aware of the issue and will include the evaluation of climate change and ESG in their due diligence. The findings are either presented in a separate ESG due diligence report or an independent section of the due diligence report.

As part of an ESG due diligence the following topics are covered:

• the use of renewable energy;
• the sustainability of the used utilities;
• the sustainability of the supply chain (carbon footprint);
• measures to reduce the impact on the climate;
• social responsibility and diversity; and
• governance (such as KYC and ESG-policies).

Depending on the company, the due diligence will lead to representatives and warranties regarding ESG compliance. Sometimes closing conditions may also be introduced. Such conditions could either be negative conditions (eg, to stop massive pollution) or positive ones (eg, investments into renewable energy).

The Austrian Renewable Energy Expansion Act (Erneuerbare Ausbau Gesetz – EAG) provides support schemes for the uptake of renewable energy technologies. The EAG was adopted in 2021 and covers the following technologies:

• photovoltaic plants (PV plants);
• biomass power plants;
• wind energy;
• hydropower; and
• green gas.

The main support scheme is a market premium. The market premium is aimed at compensating the difference between the production costs of electricity from renewable sources and the average market price for electricity. Market premiums are either granted competitively or administratively upon application (wind energy, hydropower, biomass, and biogas). The general requirements for funding vary depending on the technology.

However, it should be noted that, according to the 2025–2029 government programme, an amendment to the EAG is planned with the aim of enhancing funding efficiency and strengthening system accountability. The market premium scheme is expected to be reviewed, including an assessment of the potential introduction of contracts for difference.

Besides the EAG and the market premiums for renewable energy, there are various other subsidies for climate-friendly investments. Most of these subsidies are based on the Environmental Subsidies Act (Umweltfördergesetz) and subsequent ordinances as well as EU secondary law. From e-mobility to heat pumps, and green finance to renovation measures, there are many different subsidies for companies, communities, and even private homes.

In combination with the prohibition of oil heating in 2020 and the envisaged prohibition of gas heating by 2040, the Austrian government introduced subsidies for businesses, house owners, and tenants to switch from oil/gas to distance heating or heat pumps. The subsidies are granted for all new installations of distance heating, heat pumps, or pellet heating and cover up to 50% of the costs of the new installation. Other subsidies cover, for example, the costs for external shades for windows in order to reduce the costs for cooling in Summer and the linked negative influences on climate change. In general, the subsidies are granted upon application and will be paid as long as funding is available. In addition to the above-mentioned federal subsidies, there are plenty of regional or city-wide subsidies for climate-friendly investments in Austria. The Environmental Subsidies Act has been recently amended in June 2025.
