Howden Joinery has built credible net-zero foundations: SBTi-validated targets, 100% renewable electricity at manufacturing sites, and zero-to-landfill operations. But critical gaps remain. Water consumption is completely unreported despite operating two large factories. Scope 3 emissions lack third-party verification and multi-year absolute reduction proof. Nature impact stops at timber certification with no biodiversity targets.
