A Transformative Climate Action Framework: Putting People at the Center of Our Nation’s Clean Energy Transition

The document details five modeling scenarios for US decarbonization, comparing a business-as-usual reference case against pathways aiming for net zero emissions by 2050. It provides quantitative data on emissions, energy supply, and technology deployment, specifically highlighting the roles of electrification, renewable energy, and carbon capture.

• The modeling explores five distinct scenarios: a 'Reference' business-as-usual case based on the EIA's Annual Energy Outlook 2019, and four deep decarbonization scenarios ('Zero CO2 2050', 'Low Energy Demand', '50% Biomass Supply', and 'Renewable Build Limits'). All decarbonization scenarios assume US heat-trapping emissions are reduced by more than 50% below 2005 levels by 2030 and reach net zero by 2050.
• By 2050, the 'Zero CO2 2050' scenario projects a significant shift in electric generation, with solar PV and onshore wind providing 4,042 TWh and 3,122 TWh respectively, while coal generation drops to 0 TWh.
