Natural gas
Impacts de l’énergie sur l’environnement

The use of natural gas is growing rapidly. Its advantage is that it produces less CO₂ than coal or oil during combustion (figure 7), since it is essentially made up of methane CH₄ . Hydrogen atoms lead to water during combustion. Although water vapor is a powerful greenhouse gas (it contributes more than half of the natural greenhouse effect), the human contribution to the concentration of water vapor in the atmosphere is negligible and does not contribute to increasing the anthropogenic greenhouse effect.

Methane, on the other hand, is a very powerful...
