Legrand has cut its own emissions 56% since 2022, but its total footprint rose 22% to 10.6 MtCO2e as emissions from its products in use climbed with data-centre sales. It has SBTi-validated net-zero targets. An independent ACT assessment rated it 'not transitioning in a credible and robust way' and found it unclear about its climate-policy positions.
