Good Energy ranks highly on renewable energy sourcing (88% real-time match, 3,000+ independent generators) and has SBTi-validated near-term targets. However, Scope 3 emissions increased in 2024 due to business expansion, fleet emissions spiked 70% in 2023, and biodiversity strategy is absent. A 2023 Ofgem fine for customer overcharging and inadequate systems undercuts credibility.
