What is a greenhouse gas?
A greenhouse gas (GHG) is any gaseous compound that is capable of absorbing and emitting infrared radiation, thereby allowing less heat to escape back to space, and 'trapping' it in the lower atmosphere. The major greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and ozone (O3).

CO2 Emissions by Sector
CO2 emissions from burning fossil fuel for the following uses:
- Power Industry - Electricity production comes mostly from burning fossil fuels, mostly coal and natural gas. Greenhouse gas emissions from industry primarily come from burning fossil fuels for energy.
- Industrial Combustion - from manufacturing.
- Waste - solid waste disposed on land, solid waste composted and hazardous solid waste processing/storage, waste water handling, waste incineration.
- Fuel Exploitation - fuel extraction, transformation and refineries activities, including venting and flaring.
- Industrial Processes non-metallic minerals, non-ferrous metals, solvents and other product use, chemicals, etc
- Transportation - from burning fossil fuel for cars, trucks, ships, trains, and planes.
- Agriculture - agriculture livestock (enteric fermentation, manure management), agriculture soils (fertilisers, lime application, rice cultivation, direct soil emissions, indirect N2O emissions from agriculture), field burning of agricultural residues.
- Buildings - Commercial and residential. Greenhouse gas emissions from businesses and homes arise primarily from fossil fuels burned for heat, the use of certain products that contain greenhouse gases, and the handling of waste.
Excluded are: short-cycle biomass burning (such as agricultural waste burning), large-scale biomass burning (such as forest fires) and carbon emissions/removals of land-use, land-use change and forestry.
