Maryland greenhouse gas emissions

MIT Alumni for Climate Solutions
About 93 mega metric tons of CO2e of GHG emissions are produced annually by Maryland. (See Maryland data compared to GHG emissions from other US states and nations.) The largest amounts are produced from electricity use and transportation, with smaller amounts from industrial processes, agriculture, and waste processing (see below). About 12 mega metric tons of of CO2e are offset by forests and agricultural activities in the state. Almost three-quarters of GHGs produced in Maryland is CO2, with smaller amounts of methane, nitrogen oxides, and ozone depleting chlorofluorohydrocarbons.
