Air Liquide reports comprehensive Scope 1 and 2 emissions data with 11% absolute reduction since 2020, but total footprint fell only 2.7% as upstream Scope 3 emissions surged 67%. No quantified mid-term Scope 3 target exists. The company sits at 40% low-carbon electricity, chairs climate committees at industry groups actively opposing climate policy, and excludes hostile trade associations from disclosure.
Air Liquide scores 35/100 (Below expectations) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified May 2026.
That places Air Liquide joint 482nd of 847 companies scored, and 4th of 10 in Chemicals.
