GREENHOUSE GAS EMISSIONS SCOPE (ACCORDING TO THE GHG PROTOCOL) Scope 1: direct emissions resulting from the combustion of fossil fuels (gas, oil, coal), direct refrigerant gas emissions, direct CO 2 emissions not resulting from combustion. Scope 2: indirect emissions related to the consumption of electricity, heat, or steam required for the activity. The GHG protocol requires the calculation of the type of scope 2: that calculated on the basis of the emission factors of the average energy mix of the network (“location-based”) or that calculated taking into account the Company’s contractual energy supply choices (“market-based”). Scope 3: other emissions not resulting from the items described above.

The reference year, 2019, was chosen when the fi rst greenhouse gas emissions reduction target was set for 2020. It is not fully representative of the group’s activities because the Tricastin and Malvési sites were operating below their nominal capacity due to the renewal of production plants. This objective will reduce the group’s scope 1 and scope 2 emissions by -55% in 2030 vs. 2015 and -74% compared to 2024. In order to assess the compliance of its trajectory with the Paris Agreements, the group compares its objectives: ● to the “Fit for 55” ambitions, i.e. 55% in GHG emissions by 2030 vs. 1990, and the French national low-carbon strategy (SNBC v2 of 2020), which expects -40% in 2030 vs. 1990 and -28% in 2030 vs. 2015; and ● to the annual reduction rate (2.5%/year) used by the Science Based Target initiative (SBTI). The group’s objective is equivalent to “Well below 2°C”.

A transition plan launched in 2004 and still ongoing Orano began a program to reduce its greenhouse gas emissions in 2004. This enabled a -66% reduction in scope 1 and scope 2 market-based emissions between 2004 and 2019, in particular through new, more energy-ef fi cient facilities, a reduction in heavy fuel oil consumption and elimination of SF 6 emissions. As part of the renewal of its Commitment 2030 roadmap renewed at the end of 2024, the group is extending its commitment to maintain the 25% reduction in its scopes 1 and 2 market-based emissions in 2030 vs. 2019 in a context of increased activity. This objective is based on an industrial vision that is updated annually, on the analysis of decarbonization levers and locked-in emissions. The group took into account the expectations of its stakeholders in their development.
