Starling Bank reports low operational emissions but excludes financed emissions—the material climate impact for any bank. Its SBTi commitment was removed after failure to validate targets. Absolute emissions rose in 2023–2024 despite intensity improvements. Nature risk, water impact, and fossil fuel lending policy remain absent.
