Honda's footprint was 232.38 Mt CO2e in the year to March 2026 and has risen for two years, driven by emissions from the fuel its vehicles use, while emissions from its own operations fell. It used 1,950 GWh of renewable electricity, and more than 80% of its electricity in North America is renewable. Its Scope 1 and 2 target is absolute but not SBTi-validated, and in 2026 it halved its product CO2 intensity targets. KPMG gives limited assurance on its greenhouse gas, energy, water and waste data. InfluenceMap finds it opposed vehicle emissions standards in the US, UK, EU and Canada.
