Evolution of the antipollution applicable standards in heavy trucks and NGV positioning
This graph presents European emission standards (Euro standards) of nitrogen oxides and particles for heavy trucks, as well as measured emissions for NGV’s vehicles (WHTC cycle).
Euro standards fix the maximal limits about rejections of pollutants (nitrogen oxides, carbon monoxide, hydrocarbons and particles) for vehicles). They are stricter and stricter, seeking to limit the atmospheric pollution due to truck transport.
NGV environmental efficiency is far better than traditional fuels’ one. This efficiency can be seen through nitrogen oxides emissions or micro particles emissions. Both these pollutants are strongly concentrated within urban areas.
