The quantities are sufficient enough to affect the quality of atmospheric air.
Total amount of fossil fuel burnt was around 6.2 Gt/Yr.
Another source of pollutant emission from combustion process is the biomass.
Total amount of biomass fuel burnt was around 3 to 5 Gt/Yr.
The combustion conditions for biomass combustion leads to higher emissions. |
