Mazda reports emissions across scopes but with methodology shifts obscuring real progress. Scope 3 doubled while the company downgraded its 2031 target and lobbied against emissions standards globally. No SBTi validation, active greenwashing via tree-planting claims, and EV ambition (30% by 2030) falls far short of climate requirements.
