Panasonic has strong target-setting (SBTi-verified net-zero) and operational emissions reporting, but faces a massive Scope 3 problem: 125Mt CO2e dwarfs its 1.5Mt direct footprint, reduction pace is slow (2% annually), and renewable energy penetration remains stuck at 32.5%. Mixed trade association lobbying—particularly via Keidanren vice chairmanship—undermines climate credibility.
