BMW scores 3 points higher than Mercedes-Benz on SINK.
BMW is more sustainable according to SINK's scores, scoring 32/100 vs Mercedes-Benz's 29/100, a difference of 3 points.
BMW scores 32/100 on SINK (Below expectations). BMW's reported footprint fell 5.5% to 128.4 MtCO2e in 2025, 70% of it the fuel and electricity its cars use on the road. It targets an absolute cut of 40 Mt by 2030 against 2019, but it lobbies to weaken EU car CO2 standards and the 2035 phase-out of new combustion cars, and InfluenceMap grades it D+. Only 49% of its energy is renewable, and it sets no biodiversity targets.
Mercedes-Benz scores 29/100 on SINK (Significant gaps). Mercedes-Benz's footprint was 119.4 million tCO2e in 2025, down from 134.2 million in 2024, but the company says the fall came mainly from lower sales, and its average EU new-car CO2 rose from 103 to 106 g/km. Renewables were 46.6% of its energy use; its purchased electricity is largely green, but its plants still burn natural gas. It has SBTi-validated near-term targets from 2019 but no SBTi net-zero target, and it has offset plant emissions since 2022. In 2025 it agreed to pay $149.6m to US states over diesel defeat devices, and InfluenceMap finds it pressed to weaken EU car CO2 standards.
Both companies are rated on the same 10-question SINK rubric: Scope 1/2/3 carbon footprint, energy source, nature and biodiversity, resource use, water, emissions trajectory, science-based targets, transparency, and controversies. Scores are 0–100, based on public data, and fully reproducible.
