Greenhouse Gas Emissions Inventory (March 2024)

The climate is changing due to human activities which release greenhouse gases (GHGs) into the atmosphere and cause average temperatures to rise. Many human activities emit carbon dioxide, as well as even more powerful greenhouse gases like methane, nitrous oxide, and others. Each of these gases exist naturally in the environment, but human-built systems for energy, transportation, agriculture, and waste management are responsible for releasing climate-altering quantities of these gases. 

The Twin Cities Greenhouse Gas Emissions Inventory summarizes the sources of emissions by sector and sub-sectors for counties, the Twin Cities region, and (part of) the Minneapolis-Saint Paul-Bloomington, MN-WI metropolitan statistical area. We will build on these data throughout 2024—adding more geographic levels, emissions sources, and years—as part of the Climate Pollution Reduction Grant awarded to the Met Council in 2023 by the Environmental Protection Agency.
