E1-3 Actions and Resources in Relation to Climate Change

[E1-3.28] [MDR-A-68a-68e] This section provides an overview of the (key) actions taken in the reporting year, as well as future actions planned to address our climate change-related impacts, risks, and opportunities.

[E1-3.29a, 29b] [E1-4.34f] [E1-4 AR 30a, 30b] Reducing emissions and sustainable energy solutions play a major role in our transformational path toward becoming a net-zero business. To prevent and, wherever applicable, mitigate the impacts and risks identified for E1 Climate Change, OMV has defined the following key actions[MDR-A 69b] Key actions are defined as those requiring CAPEX of EUR ≥5 mn for their implementation. In 2025, the planning horizon was shortened from five years to three, resulting in forward-looking CAPEX that is lower compared to the Sustainability Statement 2024. CAPEX includes additions to property, plant, and equipment and to intangible assets (incl. IFRS 16 right-of-use assets) and expenditures for acquisitions, as well as equity-accounted investments and other interest for pre-defined sustainability CAPEX categories. Decommissioning assets, government grants, borrowing costs, additions to assets disposed (under certain conditions), and other additions that by definition are not considered capital expenditure are not included in CAPEX figures. Within the boundaries of applicable accounting standards, expenditure incurred during project implementation is generally capitalized, thus included in the CAPEX figures. OPEX figures related to key actions are not disclosed due to current limitations in data availability and may be included in future reports as reporting practices evolve. Figures are not validated by external bodies. For E1 Climate Change, the key actions mainly refer to activities in Europe, the majority of them being in Austria, Belgium, Germany, and Romania. Due to the threshold of EUR ≥5 mn per key action, the presented CAPEX figures do not represent the total CAPEX of OMV for actions addressing climate change mitigation., grouped under each identified decarbonization lever in the key actions table. By increasing zero-carbon sales, using more sustainable (renewable and recycled) feedstock, investing in Carbon Capture, Utilization, and Storage (CCU/S), and improving operational efficiency, we address the negative impacts related to GHG emissions from our operations and products sold. These efforts help mitigate the high emissions and significant energy consumption in continuing operations and business activities under the current business model. This makes a positive contribution to reducing GHG emissions through the energy transition, supporting society’s shift from a linear to a circular economy by offering diversified products with a reduced carbon footprint, and gradually moving away from fossil fuels toward achieving a net-zero business by 2050. Innovation is a key element in OMV’s implementation of its Strategy 2030 and critical to the transformation of the value chain from a linear to a circular model. OMV is always looking for innovative solutions to optimize operations, evaluate business opportunities, and develop new business models to make OMV more sustainable as a company.

The key actions listed in the table above build on OMV’s existing expertise as well as on the latest available technologies, which are central to OMV’s implementation of its Strategy 2030 and achieving its GHG emissions reduction targets.

[MDR-A 69b] [E1-3.29c-i] In 2025, the implementation of key actions related to E1 Climate Change required CAPEX of EUR 0.5 bn. For OMV’s total CAPEX and its reconciliation to the investments shown in the cash flow statement, see Directors’ Report: Capital Expenditure (CAPEX) and Financial Statements: Consolidated Statement of Cash Flows. [MDR-A 69b] [E1-3.29c-ii] Of the total 2025 CAPEX for implementing key actions, 68% is EU Taxonomy-aligned. Of the total planned CAPEX for implementing key actions between 2026 and 2028, 78% will likely be EU Taxonomy-aligned and part of the EU Taxonomy CAPEX plan. For details, see EU Taxonomy – CAPEX Plan.

[MDR-A 69a] OMV seeks to align its long-term funding policy with the Company’s sustainability strategy. For this reason, OMV is assessing the opportunities of sustainable financing and sustainability-linked funding, which links the cost of a financing instrument to the achievement of specific strategic sustainability targets. A first step toward sustainable financing was taken in 2021 with a green loan for the ReOil® 2000 chemical recycling plant in Schwechat, Austria. This loan was issued in alignment with the green loan principles and is based on a project-specific green financing framework and a second party opinion. For the implementation of other key actions included in the table above, no sustainable financing instrument is currently outstanding.

[E1-3 AR 21] OMV has a strong cash position (around EUR 4.4 bn reported as of the end of Q3/25). Furthermore, it typically relies on debt capital markets as its main funding source due to their efficiency, liquidity, and the availability of long(er) tenors. It aims for a broad diversification of its investor base and its funding sources and wants to maintain a balanced debt maturity profile. OMV targets efficient financing while at the same time ensuring that its funding measures support its investment-grade credit rating and its long-term leverage ratio target (16% reported at the end of Q3/25). OMV also maintains committed and uncommitted bank lines to cover short-term cash flow fluctuations. Structures that enable OMV to optimize working capital complement the palette of funding tools. Funding of future growth and the transformation process will mainly rely on a mixture of operating cash flows, contributions from further cost optimizations, and disposals. Any additional financing can be raised via the set of tools described above, in line with the cash flow profile of the investment as well as OMV’s financial priorities and long-term targets. Hybrid capital will also remain a solid pillar of our capital structure in the long term.

Progress on Specific Key Actions

Increasing Zero-Carbon Products

Scaling up sales of zero-carbon and renewable energy products while reducing fossil fuel sales is essential to lowering the carbon footprint of our energy supply. OMV’s portfolio in this area includes biofuels, electricity, waste heat, and innovative solutions such as geothermal heat.

In our Energy division, the Low Carbon Business (LCB) team is actively advancing geothermal energy and renewable power solutions. Over recent years, these initiatives have gained significant momentum, with many projects currently in the assessment or early investment phase. We plan to ramp up investment in these areas after 2027.

• A key example of our commitment is our joint venture with Wien Energie called “deeep,” which is focused on developing deep geothermal plants in the greater Vienna area. The first plant, located in Aspern (northeast of Vienna), will have a capacity of 20 MW, supported by heat pumps – enough to supply approximately 20,000 households. The drilling of three wells, each reaching depths of over 3,000 m, has been completed, with testing scheduled to be finished in early 2026. These wells will utilize hot formation water for heat generation, with first heat delivery expected in 2028. This initial geothermal plant will serve as a foundation for further expansion in Vienna. Together, OMV and Wien Energie aim to develop up to seven geothermal plants with a total capacity of up to 200 MW, enabling the production of climate-neutral district heating for up to 200,000 Viennese households.

In our Fuels division, we contribute to developing a sustainable energy system by identifying and maturing innovative solutions, especially for markets that are difficult to electrify with batteries and for customer segments like heavy road transport or air travel. These markets share a need for energy-dense, climate-friendly fuels with minimal downtime. Our portfolio promotes sustainable products like waste-based and advanced biofuels, as well as renewable fuels of non-biological origin, leveraging synergies with OMV’s existing refinery assets and expertise. The implementation of these projects is expected to reduce overall emissions, support the development of innovative and sustainable products and services, and position OMV as an active participant in the energy transition.

• The co-processing plant at the Schwechat refinery successfully started operations in June 2024. It converts up to 160,000 t of liquid biomass into renewable diesel and saves up to 360,000 t of CO₂e per year. The experience gained from operating this plant will help OMV to further optimize renewable production based on liquid biomass and support the decarbonization goals.

• In April 2025, OMV started production of the first green hydrogen at the Schwechat refinery with a new 10 MW PEM electrolyzer, currently the largest such plant in Austria. The facility can produce up to 1,500 t of green hydrogen annually, supporting sustainable fuel production and saving up to 15,000 t of CO₂ per year.

• Following this achievement, in May 2025, OMV approved the Final Investment Decision for an additional 140 MW green hydrogen project in Bruck an der Leitha, Lower Austria. Construction started in September 2025 and production is scheduled to start by the end of 2027, with a production capacity of 23,000 t of green hydrogen and an estimated reduction of approximately 150,000 t of CO₂ emissions each year, as per the business case. The green hydrogen will be transported via an underground pipeline in the Schwechat refinery and will also be utilized to produce sustainable fuels and chemicals, including sustainable aviation fuel (SAF) and renewable diesel (HVO).

• In February 2025, OMV Petrom started construction of its plant for sustainable aviation fuels (SAF) and renewable diesel (HVO), following the Final Investment Decision in June 2024. From 2028, the plant will supply around 250,000 t of sustainable fuels annually.

• OMV is delivering district heating from its Schwechat refinery to Vienna Airport and Wien Energie. A total of 705,845 MWh was delivered in 2025.

In our Retail business, OMV successfully continued its electromobility journey and implemented a full operating system including CPO (Charge Point Operator), eMSP (eMobility Service Provider), and app modules in Austria, Hungary, Romania, and Slovakia. In Romania, OMV Petrom continued to expand the EV business, including charging points operated via Renovatio following the closing of the acquisition. In September, OMV established a JV with a leading EV company in the Czech Republic, PRE, as part of which high-performance chargers at OMV filling stations and other locations will be rolled out together. By the end of 2025, OMV was operating 1,689 (2024: 804) high-performance charging points. For an overview of where these charging stations are located, see Management Review: Fields of Activity.

Carbon Capture and Storage

Together with Aker BP, OMV holds the Poseidon license to store CO₂ in the Norwegian North Sea (OMV Norge 50%). The project has the potential for over 5 mn t of CO₂ to be stored annually. We intend to use the site as storage for CO₂ captured from various industrial plants across northwest Europe, including from Borealis’ European facilities. A 3D seismic survey was successfully carried out in late 2023. A drill-or-drop decision will be made in 2027. In partnership with Vår Energi (operator) and Lime Petroleum AS, we were awarded a second CO₂ storage license in 2024 (OMV Norge 30%). The license, called Iroko, is located in the central Norwegian North Sea and can store around 215 mn t of CO₂, with the injection capacity expected to exceed 7.5 mn t of CO₂ per year. Again, a drill-or-drop decision will be made in 2027. We remain committed to evaluating promising CCS opportunities.

The following actions are related to the decarbonization lever “Improve operational efficiency” (see key actions table):

Energy Efficiency Measures

Effective carbon and energy management helps reduce GHG emissions and associated liabilities, thus lowering environmental costs, boosting financial savings through energy efficiency, and ensuring regulatory compliance. Government authorities require compliance with EU Emissions Trading System (EU ETS) regulations, national implementations of the EU Energy Efficiency Directive, and mandatory energy audits every four years. OMV’s comprehensive approach to managing GHG emissions is embedded within its strategy formulation and implementation. It is based on GHG and energy accounting and reporting, inventory management, audits, assessment plans, and training for employees.

Energy efficiency measures in OMV operations are closely linked with technical improvements directed at reducing energy use while achieving the same operational output. Process optimization and increasing energy efficiency to reduce costs and CO₂ emissions are also a priority at our refineries. In the Schwechat refinery in 2025, a project was implemented to improve the efficiency of a boiler, leading to a reduction of approximately 8,900 t of CO₂ per year. Several measures were executed, including replacing an existing air preheater with a segregated heat exchanger system. The potential for reducing energy use is identified through annual campaigns aimed at improving environmental performance, including through energy consumption. We set targets for refineries to achieve specific energy intensity index ratings, which are monitored yearly. Based on these ratings, we pinpoint areas for energy efficiency improvements and decide on measures to reduce consumption as part of our environmental governance.

Borealis accounts for 25% of OMV’s energy consumption and views energy efficiency as crucial to its climate strategy, aiming for a 10% reduction from 2015 levels by 2030. Joint facilities in Schwechat and Burghausen have initiatives to increase synergies, such as managing common intermediates and residues, resulting in energy and CO₂ savings.

Phasing Out Routine Flaring

[MDR-A-68a-68c] During oil production, associated gas is produced alongside the oil. While much of this gas is utilized, some is flared due to technical or economic constraints, releasing greenhouse gases like CO₂ and methane. Around 0.2% of OMV’s total direct GHG emissions and around 0.7% of OMV Energy’s direct GHG emissions result from routine flaring. In 2017, OMV endorsed the World Bank’s “Zero routine flaring by 2030” initiative. Existing sites where the routine flaring of associated and free gas still occurs are required to develop a phase-out plan to eliminate legacy routine flaring as soon as possible, but no later than 2030. New production sites are developed with the appropriate gas utilization solutions in place and without routine flaring. We report to the World Bank on our progress on this initiative annually. All OMV operations are also required to minimize methane emissions from point sources, as well as fugitive emissions and technically avoidable emissions (such as those from well testing and well workover, among other events). In 2025, we routinely flared 10,159 thousand Sm³ of associated gas. [MDR-A 68e] Since 2017, we have reduced routine flaring amounts by 93%.

Fugitive Emissions Monitoring and Leak Detection and Repair

[MDR-A-68a-68c] OMV systematically monitors and controls fugitive methane emissions and other non-methane volatile organic compounds (NMVOCs) through Leak Detection and Repair (LDAR) programs. Routine audio, visual, and olfactory inspections, along with soap bubble testing and optical gas imaging and other technologies, are used for leak detection. Advanced methods such as infrared cameras and collaborations with third parties using drones, satellite data, and acoustic leak imaging enhance monitoring efforts.

Leaks are repaired based on prioritization and risk assessments. Key initiatives include the pipeline integrity program and modernizing facilities like compressor stations. OMV implements LDAR programs in both upstream (OMV Energy) and downstream (OMV Fuels) sectors to address fugitive emissions. LDAR programs in OMV Energy align with the GHG Management Framework, the OGMP 2.0 Framework of the UN program for the reduction of methane emissions, which OMV joined in April 2024, and with the EU MER (Methane Emissions Regulation), which came into force in August 2024 for the sites that are subject matter. An internal and external LDAR team in OMV Austria and OMV Petrom uses advanced technologies for regular site screenings. In August 2025, OMV submitted its first LDAR reports to the respective appointed competent authorities of the Member States, as along with the annual reports with the source-level quantification of methane emissions using generic emission factors, in order to comply with the EU MER. In addition, OMV submitted its first annual OGMP report and achieved Gold Standard Pathway status for the 2025 reporting year, showcasing the Company’s strong commitment to methane management. In 2025, Upstream (OMV Energy) made further progress with methane emission monitoring and reporting, performing additional source-level methane measurements and quantification in their assets. Based on 2025 data, fugitive methane emissions account for 13% of total OMV Energy methane emissions.

Sourcing Renewable Energy for Operations

[MDR-A 68a-68c] OMV is increasingly turning to renewable sources of electricity to power our operations. One approach is purchasing renewable energy, which subsequently reduces our Scope 2 emissions. There are two ways of supplying our operations with renewable energy:

• One way is through full supply electricity contracts for our sites, which are spot-based and contracted on a one- to three-year basis. Commodity pricing risk is managed using financial risk instruments. OMV has specified that, for our refineries in Schwechat and Burghausen and our AWP sites, 50% of purchased electricity must come from renewable sources. All electricity purchased by OMV’s Austrian filling stations, the head office, and for our Austrian tank farms and pump stations is obtained exclusively from renewable sources.

• The second way is the conclusion of Power Purchase Agreements (PPAs), which secure renewable energy in combination with a certificate to prove origin and correlation. For our electrolyzer projects, PPAs play a major role in securing renewable energy to prove the generation of green hydrogen in accordance with the EU’s Renewable Energy Directive (RED II/III) requirements and delegated acts for Renewable Fuels of Non-Biological Origin (RFNBOs). Besides our electrolyzer projects, PPAs are used to serve a certain share of renewables agreed within our full supply contracts.

• Having signed three sizable PPAs in Austria and Germany with counterparties VERBUND, ImWind, and Statkraft, OMV concluded an additional PPA with Energy to secure 9 GWh/a from a PV plant in Lower Austria, with delivery starting at the end of 2026.

All of these measures have resulted in a renewables share, with 49% of the purchased electricity at the Schwechat refinery and for AWP and 82% at the Burghausen refinery, including tank farms and pumping stations, coming from renewable sources in 2025.

The power demand of OMV will grow considerably in the coming years, strongly driven by the 140 MW electrolyzer project near the Schwechat refinery. OMV therefore plans to increase our renewable electricity sourcing by concluding additional PPAs and making investments in renewable power assets. In September 2025, commercial operations started in the OMV PV Neusiedl asset. On a 80-year-old production site in Neusiedl an der Zaya, a 5.6 MWp PV plant has been built and the production corresponds approximately to the annual consumption of 1,500 households. The project design and execution was very complex due to the difficult terrain and simultaneous operations in the plants. The power will be sold to the refinery by means of an internal PPA. Several similar projects are scheduled to come on stream over the next few years.

The Chemicals segment is the largest consumer of electricity in OMV, purchasing 2,750 GWh in 2025 (2024: 2,731 GWh), which is approximately 77% (2024: 73%) of OMV’s total purchased electricity. The actions taken in previous years to source renewable electricity, such as signing new PPAs, led to 60% of Borealis’ electricity being acquired from renewable sources in 2025 (2024: >50%). This is considerable progress toward Borealis’ target of 100% renewable electricity by 2030.
