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.

Power sector COâ‚‚ emission projections in the U.S. 2023-2050, by scenario
Electricity and heat sector emissions in the United states totaled *** billion metric tons of carbon dioxide (GtCOâ‚‚) in 2023. In a stated policies scenario, emissions from this sector are projected to decrease by ** percent from 2023 levels by 2030, before falling to *** MtCOâ‚‚ by mid-century. In an announced pledges scenario, electricity and heat sector emissions would drop below zero by 2050, with technologies such as carbon removal resuting in negative emissions.
