Bayer is a multinational pharmaceutical, agrochemical, and chemical company headquartered in Leverkusen, Germany.
Bayer reports comprehensive climate data with 21.9% Scope 1&2 reductions and SBTi-validated targets, but faces systematic controversies: 170,000+ Roundup lawsuits, $11B settlements, an OECD deforestation complaint, and glyphosate biodiversity damage. Emissions trajectory is inconsistent, Scope 3 gaps remain, and reliance on offsets undermines net-zero credibility.
Bayer scores 31/100 (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 Bayer joint 564th of 812 companies scored, and 6th of 10 in Chemicals.
