​Pennsylvania Greenhouse Gas (GHG) Inventory

Chart of PA Greenhouse Gas EmissionsDEP is required by the Pennsylvania Climate Change Act to compile an annual inventory of GHGs emitted in Pennsylvania. The inventory must establish GHG emission trends and contributions of major sectors, including, but not limited to the transportation, electricity generation, industrial, commercial, mineral and natural resources, production of alternative fuel, agricultural and domestic sectors.

In 2015, (the most recent data available for the 2018 Inventory) Pennsylvania was responsible for 287 million metric tons of carbon dioxide equivalent (MMTCO2e) being emitted into the atmosphere. Production and consumption of energy accounted for 88 percent of these emissions. Pennsylvania’s forestry and land use sector sequestered over 30 MMTCO2e in 2015.
