Offshore oil and gas production will contribute to emission to air of CO2, NOx, non-methan volatile organic compounds (NMVOC), methane, and SO2. Emission to air from petroleum production occurs from energy production, flaring of gas from well testing and from venting (release of unburned gas from pipes and valves in the processes during normal operations or safety reasons). Flaring of associated gas during oil production is not permitted.
The impact of this emission is discussed in chapter Current and expected state of the ecosystem - Human activities /impact - Pollution.
