Making progressPending Review

Deloitte has validated near- and long-term net-zero targets through SBTi, with genuine absolute emission reductions across scopes and 93% renewable electricity. Supply chain emissions dominate but lack full value-chain transparency. Nature strategy remains in development; no quantified biodiversity outcomes or internal carbon pricing mechanism disclosed.
