Making progressPending Review

Good Energy leads on renewable electricity sourcing (88% real-time match, 3,000+ independent generators) and holds SBTi-validated targets. However, business expansion has offset operational efficiency gains—fleet emissions surged 70% in 2023, Scope 3 rose in 2024. Weak on biodiversity, circular economy, and water disclosure. A 2023 Ofgem fine for overcharging and inadequate systems marks a material governance failure.
