Greenhouse gas emissions from industry (EPA state inventory) in Maryland, 1990 to 2022
Greenhouse gas emissions from industry (EPA state inventory), 2022, million tonnes of CO2 equivalent. Maryland is outlined. Same source and period for every area shown. Source: U.S. Environmental Protection Agency. Boundaries: U.S. Census Bureau cartographic boundary files.
Greenhouse gas emissions of a US state allocated to the industry economic sector.
More on how it is measured
Fuel burned in factories, industrial processes such as cement, steel and chemicals, and oil, gas and coal production, including methane leaks.
In million metric tons of CO2 equivalent: carbon dioxide, methane, nitrous oxide and fluorinated gases weighted by their 100-year global warming potentials (IPCC AR5), from the EPA inventory of US emissions by state, which allocates the national inventory to the states with the same methods for every state.
Emissions are counted where they occur, so electricity is counted in the state that generates it, not the state that uses it.
The six economic sectors add up to state_ghg_emissions. EPA says these estimates are not official state data: a state's own inventory can differ because it uses other methods, data or scopes. Each annual edition recalculates the whole series back to 1990.
