Entity-specific metrics

[MDR-M.77b] The measurement of all metrics below, unless otherwise specified, is not validated by an external body other than the assurance provider.

[E1-5 AR 34] [MDR-M.77a] The total energy consumption represents the total energy used in our own operations, based on site-specific data from direct measurements, calculations, or estimations where necessary. Limitations include potential inaccuracies in estimations when direct data is unavailable. [E1-5.37a, 37b, 37c] [E1-5 AR 34] The energy consumption is reported separately for non-renewable, nuclear, and renewable sources. The share of each source is calculated as a percentage of total energy consumption, using the same boundaries as Scope 1 and 2 GHG emissions. [MDR-M.77b] Some data included in this metric undergoes verification by an external body when the fuel consumption is directly correlated with GHG emissions under a regulated emissions trading system.

[E1-5 AR 34] [MDR-M.77a] The total energy consumption from fossil fuel sources represents the aggregated energy consumed from fossil fuels, based on site-specific direct measurements, calculations, and, where needed, estimations. Limitations include potential inaccuracies in estimations when direct data is unavailable. [E1-5.38a, 38b, 38c, 38d] [E1-5 AR 34] The total is reported separately for coal and coal products, crude oil and petroleum products (diesel, heating oil, and residue/waste oil, as well as other liquid fuels), natural gas (natural gas, residual gas, and other gaseous fuels), and other fossil fuel sources (FCC coke and other solid fuels). [MDR-M.77b] Some data included in this metric undergoes verification by an external body when the fuel consumption is directly correlated with GHG emissions under a regulated emissions trading system.

[E1-5.38e] [E1-5 AR 34] [MDR-M.77a] The total consumption of purchased energy represents the aggregated consumption of purchased electricity, heat, steam, and cooling, based on site-specific measurements and provider invoices. [E1-5.37b, 37c] [E1-5 AR 34] The source – fossil, renewable, or nuclear – is determined using either a market-based approach (supplier-specific mix) or, if unavailable, a location-based approach (general local energy mix). Limitations include possible inaccuracies in provider data, measurement errors, reporting delays, and the need to use prior-period energy mix data if supplier information is not available. [Entity-specific] The consumption is reported separately for each energy source and type.

[E1-5.37c] [E1-5 AR 34] [MDR-M.77a] Self-generated non-fuel renewable energy for own consumption: the aggregated self-generated non-fuel renewable energy for own consumption refers to the generation of electricity using solar photovoltaic (PV) technology for our own consumption in operated assets. This is derived from site-specific measurements recorded at the solar PV station. A potential limitation of such measurements is the accuracy and reliability of the meter equipment.

[E1-5.37c] [E1-5 AR 34] [MDR-M.77a] Total fuel consumption from renewable sources, including biomass: the aggregated fuel consumption from renewable sources is derived from site-specific information, utilizing a combination of direct measurements, calculations, and estimations. When direct measurements or calculations are not feasible, estimations are used to determine the fuel consumption. Potential limitations of the methodology include the accuracy and reliability of estimations when direct measurements and calculations are not feasible.

[E1-5.39] [MDR-M.77a] Total energy production (to market) represents the total volume of energy products sold to third-party customers, based on invoiced amounts and documented transactions; intracompany sales are excluded. Results are reported separately for renewable sources (e.g., biofuels such as sustainable aviation fuel) and non-renewable sources (e.g., fossil fuels, electricity from natural gas).

The 2024 figure has been restated following the March 2025 reclassification of the Borealis Group, excluding Borouge investments, as “held for sale” and “discontinued operations.” The 2025 figure excludes Borealis.

2

Entity-specific metric. Calculated as total energy consumption divided by revenues, excluding the Borealis Group, due to its reclassification (excluding Borouge investments) as “held for sale” and “discontinued operations.”

3

The corresponding ESRS metric, “Total energy consumption per unit of sales revenue” (2025: 0.002 MWh/EUR), is calculated as total energy consumption including Borealis divided by sales revenues excluding Borealis. This approach is applied due to diverging scope definitions relating to the reclassification of Borealis as “held for sale” and “discontinued operations” for IFRS revenue recognition (see Note 4) and environmental performance metrics. The 2024 comparable metric has also been restated (0.002 MWh/EUR).

[E1-5.40] [E1-5.41] [E1-5 AR 36a-36e] [E1-5 AR 37] [E1-5 AR 38] [MDR-M.77a-77d] Total energy consumption per unit of sales revenue from activities in high and low climate impact sectors: the energy intensity per unit of sales revenue refers to the total energy consumption in both high and low climate impact sectors over the total sales revenues in EUR. A breakdown of the energy consumption from activities in the high climate impact sectors and low climate impact sectors is not available. The sales revenues are disclosed in the financial statement. Aside from the assurance provider, the measurement of these metrics is not validated by an external body. This metric also refers to the other metrics reported under [E1-5.37a-37c] [E1-5.38a-38e] [E1-5.39 AR 34].

[E1-5.42] [E1-5 AR 33] OMV’s main NACE codes are C.19.2. Manufacture of refined petroleum products, B.6.2. Extraction of natural gas, B.6.1. Extraction of crude petroleum, and C.20.16 Manufacture of plastics in primary forms. All disclosed energy consumption numbers reflect consumption in both high and low climate impact sectors.

Certified Energy Management Systems

[Voluntary] [MDR-M.77c] 57% of sites are ISO 50001 certified (2024: 59%).

[Voluntary] [MDR-M.77a, 77b] Percentage of sites ISO 50001 certified: this figure refers to sites that are ISO 50001 certified over the total number of operational sites multiplied by 100. Aside from the assurance provider, this metric is not validated by an external body.
