Triodos leads on financed emissions disclosure (100% PCAF coverage since 2019) and rejected net-zero greenwashing by leaving the NZBA. Its 28% reduction in financed emissions (2020–2024) and upgraded 42% target by 2030 are absolute, not offset-based. Weaknesses: biodiversity baselines only set in 2024, water and waste programmes lack detail, and board compensation remains unlinked to sustainability KPIs.
Triodos Bank scores 65/100 (Leading practice) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified May 2026.
