Monzo reports comprehensive carbon data but absolute emissions rose 17% year-on-year, undermining its net zero 2030 claim. Financed emissions—critical for banks—are entirely absent. The company lacks third-party verification, SBTi validation, and a formal sustainability report despite holding £16.6B in deposits.
