Sustainability Strategy and ESG Model

To achieve Net Zero Scope 1, 2 and 3 by 2040, Plenitude has defined a decarbonization strategy that includes increasing power production from renewable sources by increasing the installed capacity of plants, selling power certified by guarantees of origin^[1] and solutions aimed at reducing energy consumption, developing services dedicated to electric mobility and, finally, offsetting remaining CO₂ emissions through carbon offsets.

[1] As fed into the grid and produced by plants 100% fuelled by renewable sources (in compliance with existing laws on the topic).

[2] Substantially in line with the 2024 value, net of the accounting treatment of the renewable assets in France (756 MW) classified as assets held for sale.

[3] Emission Intensity Indicator expressed in g CO2eq./kWh. The calculation is made by comparing Scope 1, 2 and 3 emissions with the power generated added to the power purchased for sale. For Scope 3, only emissions from marketed electricity (cat. 3 according to the GHG Protocol) were included.

[4] Figure derived from the sum of Scope 1, Scope 2 (Location Based method), and post-offset Scope 3 of 2025. Post offset Scope 3 emissions are calculated by subtracting carbon credits (3.2 Mt CO2eq., see note 5) from total Scope 3 emissions. For more information on the trend in emissions compared to last year, see section “2.2 Direct and indirect emissions” of Plenitude Sustainability and Impact Report 2025.

[5] Given by the sum:

• 0.14 Mt CO2eq. representing the difference between the estimated and actual carbon credits associated with offset gas supplies for Q4 2024, cancelled in October 2025.
• 3.06 Mt CO2eq. representing the estimated purchase of carbon credits that will be finalised during 2026 associated with the 2025 offsetting gas supplies. Of this amount, 1.93 Mt CO2eq. related to the gas consumption billed to Plenitude’s customers from January 2025 to September 2025 was offset in February 2026. The remaining portion, related to gas consumption billed from October to December 2025 and estimated at 1.13 Mt CO2eq., will be offset by October 2026.

[6] Avoided emissions are emissions that would have been released if a particular action or intervention had not taken place; some emissions can be avoided by using a more efficient and/or less emissive product or service (e.g. using renewable energy sources instead of fossil fuels) resulting in fewer third-party emissions. For more information see section “2. Climate and Emissions” of Plenitude Sustainability and Impact Report 2025.

Plenitude manages its activities with respect for all stakeholders and operates with the aim of using natural resources responsibly, pursuing a business model focused on greater sustainability and integrating ESG aspects throughout the value chain.
