Sanofi's own emissions are 49% below 2019, but its total of 4.45 MtCO2e was flat in 2025 because its supply-chain emissions rose slightly. Its targets are SBTi-validated, though its supply-chain target is in line only with 2°C. 86% of its electricity is renewable, much of it through unbundled certificates, but renewables are only 43% of all its energy. InfluenceMap finds it belongs to trade groups that oppose climate policy, including the US Chamber of Commerce.
