ORANO // Annual Activity Report 2024

SUSTAINABILITY STATEMENT

Environmental information

4.2.1.4 A continuous and renewed effort on our carbon footprint Aware of the climate change mitigation issue, the nuclear industry regularly conducts studies of its greenhouse gas emissions over the entire life cycle. Emissions associated with the fuel cycle are the largest carbon impact item. The decarbonization of the cycle’s activities is thus a major challenge in terms of compliance with the Paris Agreement and setting an example.

In addition to being convinced that nuclear power can play an essential role in the energy transition towards low-carbon electricity, Orano has been involved in a program to reduce its own emissions since 2004 in order to contribute to the global issue of carbon neutrality.

The group’s transition plan for climate change mitigation This transition plan is presented annually to the Board of Directors as part of the presentation of the group’s strategy and fi nancial trajectory. Greenhouse gas emissions can be broken down into three scopes, illustrated below.

THE THREE SCOPES OF GREENHOUSE GAS EMISSIONS

Upstream value chain

Company perimeter

Downstream value chain

Upstream scope 3

Scopes 1 & 2

Downstream scope 3

SCOPE 1 Fuel consumption

Purchased goods and services Fuel-and-energy related activities

Waste generated in operations

Processing and use of sold products

End-of-life treatment of sold products

4

(stationary and mobile sources) Fugitives and process emissions Emissions from biomass (soil and forest) use

SCOPE 2 Emissions related to electricity, steam, heat or cooling consumption

Upstream transportation

Investments

Downstream transportation

Capital goods

Business travels Employee commuting

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, heating, 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.
