Mizuno's footprint was 426,713 tCO2e in its 2025 financial year (to March 2026), mostly in its supply chain, down from 448,358 t the year before, though Scope 3 had risen the year before that. It publishes no renewable electricity share and is not in RE100; part of its Scope 2 cut in Japan comes from certificates. The SBTi validated its targets in 2024: an absolute 50.4% cut in Scope 1 and 2 by 2030 from 2018, and a 58.1% cut in Scope 3 per unit of value added, an intensity target. External assurance covers only two Scope 3 categories. Industrial waste at its factories rose 20.3%.
