Below expectationsPending Review

Santander reports strong operational emissions reductions and 100% renewable electricity in core markets, but this masks a systemic failure on financed emissions. The bank weakened its fossil fuel policy, ranks among top 25 banks financing fossil fuel expansion, and distributed 'green' bonds tied to deforestation and labour abuses. Operational performance cannot offset portfolio harm.
