Texas and California have consistently been the two biggest transportation-related carbon polluters in the U.S. In 2022, they emitted 219 and 183 million metric tons of carbon dioxide (MtCO₂), respectively. Combined, these two states – the most populous in the U.S. – account for almost a quarter of U.S. transportation CO₂ emissions.

Changes in U.S. state transportation emissions

As of 2022, 30 U.S. states had observed overall transportation-related emission reductions when compared to 2005 levels. The state with the largest emissions reductions during this period was New Jersey, at 37 percent. In contrast, Texas’ transportation emissions grew by more than 13 percent over this timespan.

Transportation’s share of emissions

In 2022, transportation accounted for at least 50 percent of total energy-related CO₂ emissions in nine U.S. states. In California, this figure stood at 56. Meanwhile, transportation accounted for 33 percent of energy-related CO₂ emissions in Texas, despite it being the biggest transportation-related polluter in the U.S.
