Mazda's footprint was 62,978,000 tCO2e in the year to March 2025, up on the previous year, and most of it comes from the fuel and electricity its cars use. Renewables were about 1% of its energy, and its Hiroshima and Hofu plants still run coal-fired power units. Its targets are self-set, with no SBTi target, and in September 2025 it cut its 2031 domestic target from a 69% to a 46%-or-more reduction. It has cut group water intake in Japan by 37% against its 2013 base, and CDP put it on its 2025 water A List. InfluenceMap finds it asked the US EPA to weaken proposed vehicle greenhouse gas standards.

40% of them were published by Mazda Motor itself; the rest come from independent sources.
12 of 20 sources are independent of the company.
“Total Scope 1, Scope 2, and Scope 3 greenhouse gas emissions of 62,978,000 t-CO2e”
“Scope 2 is calculated using market-based”
“Mazda has received the third-party verification to improve the reliability of the data disclosed our Environmental data and Social data.”
“In 2021, we began collecting data on Scope 1 and Scope 2 CO₂ emissions by Tier 1 suppliers”
“In FY March 2012, the Company conducted an assessment of its impacts on biodiversity”
“The next challenge is phasing out coal-fired power plant and shift to renewable energy”
“Mazda has set a target to reduce the total volume of water intake across the entire group in Japan by 38% in fiscal year 2030”
“Mazda's score of CDP 2024 was B in the Climate”
“Mazda has not published an industry association review.”
“The three lowest-scoring automakers by climate policy engagement are all Japanese (Toyota, Suzuki and Mazda)”

“he says the trees would offset less than 0.1 per cent of emissions from the manufacture and use of a Mazda CX-5”
“To actually offset the CX-5's fuel emissions, you'd need roughly 41,000 native trees — not five.”
“To meet fleet emission targets in the EU and avoid fines, Japanese carmaker Mazda is forming a CO₂ pool with its Chinese joint venture Changan Mazda.”
