Subaru's footprint was 35,900 thousand tCO2e in the year to March 2026, mostly from the fuel its cars burn. It has fallen for two years but is still above the year to March 2022, and the figures are not externally assured. Renewables supplied 25.7% of its electricity. Its targets are self-set, with no SBTi commitment, and its goal for battery-electric cars to make up half of global sales has been pushed beyond 2030. Its plants send almost no waste to landfill, but its water use is rising. InfluenceMap finds it lobbied to weaken US fuel economy standards and to delay the UK ZEV mandate.
