Analyzing energy-related carbon dioxide emissions in the U.S. based on various growth assumptions, fuel sources, and economic scenarios from the Annual Energy Outlook 2021. The data includes historical trends, projections, sector-wise breakdown, and the impact of oil and gas supply assumptions on carbon emissions. Explore how macroeconomic factors and oil prices influence emissions levels over the coming decades.
