Natural gas is the cleanest and most efficient of the fossil fuels. For electricity generation, it has low investment costs and offers flexibility. But it is one of the less exploited fossil fuels, and could yet provide a significant contribution to reducing greenhouse gas emissions.

Over 100 countries hold reserves of natural gas, and it is estimated that the global total of known reserves is 186 trillion cubic metres. The largest reserves are situated in the Russian Federation, Islamic Republic of Iran and Qatar respectively.

Natural gas is a mixture of hydrocarbons, and often contains a small amount of non-hydrocarbons. It can exist either as a gas or in solution with crude oil, where producers can then separate the two in the production process.

All data represented in the graphs and charts on this website represents natural gas data only.
