Methane and Volatile Organic Compounds Emissions
Last year, 41,200 tonnes of CH
4
were emitted, a 30 per cent net reduction since 2000. In 2015, 37,200 tonnes of
VOCs were emitted from offshore installations, a net reduction of over 53 per cent since 2000. Values for CH
4
and
VOCs in 2015 are consistent with those emitted since 2012.

CH
4
or natural gas is a potent GHG and so Oil & Gas UK has carried out further analysis to identify the offshore
sources of CH
4
emissions, as well as VOCs.
Figure 11 shows that the largest sources of VOC emissions in 2015 were gas flaring and venting (66 per cent) and
oil loading (28 per cent), while the majority of CH
4
emissions were generated from venting.
