Map showing global emissions from fossil fuel (oil, gas and coal) exploitation in 2016. Emissions are shown from yellow (0.1 milligrams per year per metre squared) through orange, red (1 mg/year/m2) and purple to blue (10 mg/year/m2). Emissions include those from the extraction, transport and storage of the fossil fuels, but not their burning. The largest source of emissions in the USA is natural gas, while it is oil in Russia and coal in China. Lines on the map correspond to gas and oil pipelines. Methane is a powerful greenhouse gas and nations have pledged to cut their emissions by 2030. Data from the UN Framework Convention on Climate Change (UNFCCC).
