Tiffany has credible absolute emission reductions and SBTi-validated net-zero targets, but supply chain opacity remains severe. Mining-linked Scope 3 emissions dominate its footprint with only 13% of suppliers committed to climate targets. Water data is entirely absent, biodiversity risk is unquantified, and third-party verification gaps persist despite consistent annual reporting.
