Referencing data provided by the U.S. Energy Information Administration, 24/7 Wall St. pinpointed some of the states accountable for the most significant increases in greenhouse gas emissions. The ranking is based on the percentage change in total energy-related carbon dioxide emissions between 2020 and 2021, the most recent data available. These emissions originate from sources that include commercial, industrial, transportation, residential, and power generation. Data on carbon emissions per capita is also from the Energy Information Administration.

Why This Matters

Firefighters team battle a wildfire because climate change and global warming is a driver of global wildfire trends.

The U.S. emits about five billion metric tons of carbon dioxide annually (as of 2021). This is more than twice that of all 28 countries of the European Union. Historically, the U.S. has released the most CO2 of any country since 1850. Since carbon dioxide is a long-lived greenhouse gas that stays in the atmosphere for thousands of years, the U.S. must accept responsibility for its major part in global warming. As the detrimental economic effects of global warming cannot be stressed enough, we are writing this article to sensitize you to which states still have a problem, and which states are moving forward in combatting this problem.

These are states where carbon emissions are on the rise:
