Carbon dioxide (CO2) emissions from the use of fossil fuels are the primary cause of climate change. The U.S. Carbon Monitor is part of an international initiative providing for the first time regularly updated, science-based estimates of daily CO2 emissions of individual U.S. states. Comparing year-to-year data reveals the effects of the COVID pandemic and patterns of sectoral emissions during the recovery.
