The Stated Policies Scenario (STEPS): This scenario offers an overview of the expected trajectory for the energy system, grounded in a thorough analysis of existing policy frameworks.
Announced Pledges Scenario (APS): This scenario presents a path for the energy sector assuming that all national energy and climate commitments, including long-term net-zero emissions targets, are fully achieved and adhered to on schedule.
Net Zero Emissions by 2050 (NZE) Scenario: This scenario outlines a pathway where the global energy sector reaches net zero carbon dioxide (CO₂) emissions by 2050, in alignment with the goal of keeping the long-term global average temperature rise to 1.5 degrees Celsius (°C).

Global electricity COâ‚‚ emissions projections 2023-2050, by scenario
Global carbon dioxide emissions from the electricity and heat sectors amounted to roughly **** billion metric tons (GtCOâ‚‚) in 2023. Under current policy settings, emissions from these sectors are projected to fall by ** percent by 2040, to just below ** GtCOâ‚‚. Under the Net Zero Emissions by 2050 scenario, in constrast, electricity and heat-related emissions would drop to less than *** MtCOâ‚‚ by 2040.
