Methodology
To identify the states where carbon emissions are rising fastest, 24/7 Wall St. reviewed data from the U.S. Energy Information Administration, a division of the Department of Energy. States are ranked on percent change in energy-related carbon dioxide emissions from 2020 to 2021.
We also reviewed five-year changes – 2017 to 2021 – in carbon emissions by state, though this longer term trend was not considered in the ranking.
Data on carbon emissions per capita is also from the Energy Information Administration.
