GHG emissions projections in the U.S. 2030, by subsector and scenario
U.S. greenhouse gas emissions from light-duty vehicles (LDVs) are projected to range between 687 and 754 MtCO₂e in 2030, under the joint action scenario. U.S. emissions from LDVs, which include passenger cars and light-duty trucks, totaled 1.05 GtCO₂e in 2021. Under the joint action scenario, the three largest contributors to U.S. GHG emissions in 2030 would be tailpipe emissions from LDVs, fossil fuel use in buildings, and fossil-fired power plants.
