National Grid reports comprehensive emissions data and meets SBTi near-term targets, but FY25 saw absolute emissions rise across all scopes despite historical reductions. US operations remain fossil-fuel dependent; methane leak lawsuits and climate policy obstruction weaken credibility. Water reporting is inadequate for a utility of this scale.
