Compared to other major energy sources, natural gas has a lower impact on the environment. Considered as the cleanest fossil fuel, it contributes to a sustainable energy market. By replacing other fossil fuels by natural gas, polluting emissions into the atmosphere and the impact on the climate can be reduced. During its combustion, natural gas produces 25% less CO2 than oil does. Furthermore, it produces very little nitrogen oxide (NOx) and hardly any sulfur dioxide (SO2).

In terms of impact on human, natural gas is less harmful as it spreads 300 times less dust and fine particles which are dangerous to health.


Natural gas is not toxic and is odourless. For safety reasons and to be able to detect a leak, an odoran is added.

Biogas, produced from green waste, domestic waste and wastewater sludge and injected into the distribution network lowers even further the polluting load. Natural gas contains a sizeable proportion of renewable gas, CO2 neutral, which is produced from the fermentation of various wastes.


Transported via underground gas pipelines, natural gas is discrete. It does not hinder travel conditions (road or rail transport is not used) and does not deface the landscape. Furthermore, it does not cause environmental or noise nuisances and air quality is preserved.

Natural gas for vehicles (CNG) - cost-effective and environmentally-friendly alternative 


By using natural gas for vehicles, the detrimental consequences of our need for mobility can be reduced to a minimum. It has a strong environmental potential and is a cost-effective alternative.
