3.1 Pollutant emissions

Pollutant emissions must comply with local or national regulations, which may evolve in line with technological advances, imposing the "Best Available Technology" or BAT.

The pollutants subject to regulation are carbon monoxide CO, nitrogen oxides grouped under the name NO _x , sulfur oxides SO ₂ . Not directly regulated, but always monitored by manufacturers, are also taken into account the black carbon dust that makes the smoke plume visible and the unburned hydrocarbons (HC) that often accompany high CO emissions. The greenhouse effect, which explains global warming, leads to the limitation of carbon dioxide emissions through emissions permits...
