Making progressPending Review

Monzo publishes full carbon data and has made renewable energy progress, but absolute emissions rose 17% year-on-year while financed emissions—the dominant impact lever for a bank holding £16.6B in deposits—remain unmeasured. A net zero 2030 target lacks SBTi validation and credibility given rising absolute footprint.
