TSB Bank scores 41/100 (Below expectations) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified May 2026.
That places TSB Bank joint 334th of 809 companies scored, and joint 13th of 46 in Financial Services / Banking.
TSB shows basic operational carbon management but critical gaps in financed emissions disclosure and supply chain accountability. The bank claims SBTi alignment but hasn't validated targets in four years. Biodiversity and nature risk are entirely absent from strategy. A £36B lending book with no quantified Scope 3 reporting is indefensible.

TSB Bank is a UK retail and digital banking group founded in 2013, headquartered in Edinburgh. It serves personal and business customers with deposits, mortgages, and lending products. As a mid-sized challenger bank without investment banking operations, its direct environmental footprint is lower than universal banks, but its £36B mortgage portfolio carries significant financed emissions exposure.
