M&S has cut operational emissions 32% but total footprint is rising as Scope 3 grows 37% in recent years, outpacing revenue gains. Supply chain measurement relies heavily on modelling rather than primary data. Post-2025 deforestation targets remain unset, and net-zero validation was delisted by SBTi in 2024.
