WASHINGTON, D.C.—U.S. greenhouse gas (GHG) emissions increased 2% in 2013 compared to the previous year, according to the latest data contained in the recently released Greenhouse Gas Inventory by the U.S. Environmental Protection Agency (EPA). EPA attributed the increase to the growing economy, declining coal prices and a cold winter. Emissions grew in 2013 across nearly all sectors, including electricity generation, vehicle miles traveled and industrial production, according to the EPA. Power plants accounted for 31% of all GHG emissions, with transportation accounting for 27% and industry and manufacturing contributing 21%. However, in total, U.S. greenhouse gas emissions have dropped 9% over the last 10 years.
