Global Greenhouse Gas Emissions Data | US EPA

Global Emissions by GasGlobal Emissions by Economic SectorTrends in Global EmissionsEmissions by CountryAt the global scale, the key greenhouse gases emitted by human activities are: 1. Carbon dioxide (CO2): Fossil fuel use is the primary source of CO2. CO2 can also be emitted from direct human-induced impacts on forestry and other land use, such as through deforestation, land clearing for agriculture, and degradation of soils. Likewise, land can also remove CO2from the atmosphere through reforestation, improvement of soils, and other activities. 2. Methane (CH4): Agricultural activities, waste management, energy use, and biomass burning all contribute to CH4emissions. 3. Nitrous oxide (N2O): Agricultural activities, such as fertilizer use, are the primary source of N2O emissions. Fossil fuel combustion also generates N2O. 4. Fluorinated gases (F-gases): Industrial processes, refrigeration, and the use of a variety of consumer products contribute to emissions of F-gases, which include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (Sulfr hexafluoride). Black carbon is a...Get price

Greenhouse Gas Emissions Standards in the United States

The CAFE standards establish mandatory fuel efficiency minimums for vehicles sold in the United States and imposes financial penalties on auto manufacturers unable to meet the regulations.

The decline in total emissions—from 6,983 million metric tons carbon dioxide equivalent (MMTCO2e) in 2008 to 6,576 MMTCO2e in 2009—was the largest since emissions have been tracked over the 1990-2009 time frame. It was largely the result of a 419-MMTCO2e drop in carbon dioxide (CO2) emissions (7.1 percent). There was a small increase of 7 MMTCO2e (0.9 percent) in methane (CH4) emissions, and an increase of 8 MMTCO2e (4.9 percent), based on partial data, in emissions of man-made gases with high global warming potentials (high-GWP gases). (Draft estimates for emissions of HFC and PFC substitutes for ozone-depleting substances in 2009 are included; 2008 data are used for emissions of other high-GWP gases.)
