Sainsbury's has cut operational emissions 52.8% since 2018 and switched to 100% renewable electricity, backed by SBTi validation. Scope 3 accountability lags: while targets exist, absolute reduction evidence is sparse. A 2019 deforestation link and unresolved supply chain traceability remain material weaknesses.
