Lloyds Banking Group scores 3 points higher than NatWest Group on SINK.
Lloyds Banking Group is more sustainable according to SINK's scores, scoring 43/100 vs NatWest Group's 40/100, a difference of 3 points.
Lloyds Banking Group scores 43/100 on SINK (Below expectations). Lloyds reports material financed emissions (18.6 MtCO2e) and owns a 36% reduction since 2018, but relies heavily on estimated data, supply-chain emissions are rising, and an ASA ban for misleading climate advertising exposes credibility gaps. Operational footprint is low for banking, renewable energy secured, but nature exposure through agriculture is unmapped.
NatWest Group scores 40/100 on SINK (Below expectations). NatWest has cut operational emissions 66% since 2019 and achieved 100% renewable electricity, but undermined these gains by voluntarily withdrawing SBTi validation in 2025 and weakening oil & gas lending policy in February 2026. Fossil fuel financing rose 31% year-on-year; financed emissions remain the dominant unresolved impact.
Both companies are rated on the same 10-question SINK rubric: Scope 1/2/3 carbon footprint, energy source, nature and biodiversity, resource use, water, emissions trajectory, science-based targets, transparency, and controversies. Scores are 0–100, based on public data, and fully reproducible.
