About gas

Gas plays a vital role in Europe’s energy mix. It is one of the cleanest, safest and most reliable sources of energy. It offers answers to meeting Europe’s ambitious climate targets in a secure and sustainable way. Gas is also the fuel of choice for energy efficiency and comfort; over 200 million European citizens opt for gas to warm their homes, while gas also provides electricity and increasingly is fuelling cars.

Achieving decarbonisation and an affordable energy transition by deploying renewable energy sources is an important solution to reaching the EU’s ambitious 2030 targets. Natural gas can also make a significant contribution to reducing CO2 emissions, including by complementing the expansion of renewable energies.

Gas is mainly composed of methane (CH4) with other constituents in very limited quantities (mainly carbon dioxide [CO2], alkanes, etc.). Natural gas can have many origins – some mineral, some fossil and some biogenic (bacteria).

Gas is one of the cleanest traditional sources of energy: when burnt, it emits up to 50% less CO2 than other fossil fuels and has lower emissions of nitrogen oxide (NOx), sulphur oxide (SOx) and particles.

It can also be renewable, produced from various feedstocks, agricultural residues, municipal waste or sewage, in the forms of biomethane, hydrogen or synthetic gas. Renewable gas can also be produced from excess electricity generated by variable renewable sources (such as solar and wind).
