BYD's absolute emissions have surged 50% year-on-year despite intensity targets. Supply chain emissions largely undisclosed; Scope 3 use-of-products missing entirely. Operational transparency improving but unverified; greenwashing ruling and documented pollution allegations undermine credibility.
BYD Company scores 25/100 (Significant gaps) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified July 2026.
That places BYD Company joint 728th of 847 companies scored, and 21st of 24 in Automotive.
