IEA updates Net Zero Roadmap, urging tripling of renewables by 2030

In September 2023, the International Energy Agency, led by Executive Director Fatih Birol, published an updated Net Zero Roadmap concluding that the path to limiting warming to 1.5C requires tripling global renewable-power capacity by 2030 and that no new long-lead fossil-fuel supply projects are needed.

In September 2023, the International Energy Agency, led by Executive Director Fatih Birol, published an updated Net Zero Roadmap concluding that the path to limiting warming to 1.5C requires tripling global renewable-power capacity by 2030 and that no new long-lead fossil-fuel supply projects are needed. The analysis became a key reference for the COP28 agreement to triple renewables. Birol has used the IEA's authority to argue that clean-energy growth, not fossil expansion, is the central trend of the global energy system.
