IEA – Net Zero Roadmap, 2023

The International Energy Agency (IEA) has released an updated version of its Net Zero Emissions by 2050 (NZE) Scenario, which outlines a pathway for the energy sector to achieve net zero CO2 emissions by 2050 and contribute to the 1.5 °C global warming goal. The report highlights that the case for transforming the global energy system in line with the 1.5 °C goal has become stronger, with increasingly severe impacts of climate change. While global carbon dioxide emissions from the energy sector reached a record high in 2022, the IEA projects that demand for coal, oil, and natural gas will peak this decade even without new climate policies. Positive developments include the growth of solar PV installations and electric car sales, as well as measures announced by governments to promote clean energy technologies. The report emphasizes the need to ramp up renewables, improve energy efficiency, cut methane emissions, and increase electrification to drive fossil fuel demand down. Tripling global installed renewables capacity and doubling the annual rate of energy intensity improvement are key actions to achieve emissions reductions by 2030. The report also underscores the importance of accelerating electrification and cutting methane emissions. Finally, the IEA highlights the need for continued innovation, infrastructure expansion, and the adoption of carbon capture, hydrogen, and sustainable bioenergy technologies to achieve net zero emissions.
