World Energy Outlook 2021.

Author(s) : IEA

Type of monograph: Report


In the run-up to a crucial COP26 meeting in Glasgow, this World Energy Outlook-2021 (WEO-2021) provides a detailed picture of how far countries have come in their clean energy transitions, and how far they still have to go. In a momentous period for the future of energy and emissions, this World Energy Outlook uses several long-term scenarios to illustrate the choices that face the world’s decision makers. The main scenarios in this Outlook are:
1) Net Zero Emissions by 2050 Scenario (NZE), which sets out a narrow but achievable pathway for the global energy sector to achieve net zero CO2 emissions by 2050.
2) Announced Pledges Scenario (APS), which assumes that all climate commitments made by governments around the world, including Nationally Determined Contributions (NDCs) and longer term net zero targets, will be met in full and on time.
3) Stated Policies Scenario (STEPS), which reflects current policy settings based on a sector-by-sector assessment of the specific policies that are in place, as well as those that have been announced by governments around the world.
