CO2 Emissions | World

Carbon dioxide emissions account for the largest share of greenhouse gases which are associated with climate change and global warming. Data for carbon dioxide emissions include gases from the burning of fossil fuels and cement manufacture, but excludes emissions from land use such as deforestation. Oil releases about 50 percent more carbon dioxide than natural gas, and coal releases about twice as much. Carbon dioxide emissions are often calculated and reported as elemental carbon. The unit of measurement is kt (kiloton).
