ENVIRONMENT REPORT 2018

UKCS Carbon Dioxide Emissions Hydrocarbon production increased by almost 13 per cent between 2014–17, and over the same period CO 2 emissions saw a 12.5 per cent increase. 2017 saw increasing CO 2 emissions on the UKCS with a rise from 13.1 million tonnes to 14.2 million tonnes. Offshore installations are not connected to the national grid for power supply. Power is generated offshore to run pumps, equipment used in production processes, for electricity used for cooking, lighting and heat, as well as for compression equipment so that oil and gas can be transported onshore. CO 2 is also emitted during flaring and venting offshore, which are necessary for maintenance, well testing and, crucially, for the safety of offshore workers. Seventy-one per cent of CO 2 emissions (10.1 million tonnes) in 2017 were generated from fuel consumed by combustion equipment to provide electrical power and drive compressors for oil and gas export.
