Global Emissions

Global Emissions by Source

• Energy Supply (26 % of 2004 global greenhouse gas emissions) - The burning of coal,natural gas and oil for electricity and heat is the largest single source of  global greenhouse gas emissions)

• Industry  (19% of 2004 global greenhouse gas emissions) - Greenhouse gas emissions from industry primarily invovle fossil fuel s burned on-site at facilities for energy, also includes emissions from chemical, metallurgical and mineral transformation porocesses.

• Land use, change  and Forestry    (17 % of 2004 global greenhouse gas emissions) - Greenhouse gas emissions from this sector primarily include Carbon dioxide emissions from deforestation, land clearing for agriculture and fires or decay of peat soil.

•  Agriculture  (14 % of 2004 global greenhouse gas emissions)-  This comes mostly from the management of agriculture soils ,livestock,rice production, and biogass burning.

• Trasnportation  (13 % of 2004 global greenhouse gas emissions)- This sector primarily invovles fossil fuels burned for road, rail, air and marine transportation. Almost 95% of the world's transportation energy comes from petroleum-based products.

• Commerical and Residential Buildings  (8% of 2004 global greenhouse gas emissions)-  Emissions from this sector arise from on-site energy generation and burning fuels for heat in buildings or cokkoing in homes.

• Waste and Wastewater  (3% of 2004 global greenhouse gas emissions) - The largest source of greenhouse gas emissions in this sector  is  landfill methane (CH4), followed by waste water methane and nitrous oxide (N2O).  Incineration of  some waste products that were made with fossil fuels, such as plastics an synthetic textiles, also results in minor emissions of CO2.
