Refinery CO 2 Emissions
Mt Refinery CO 2 Emissions
As a result of decreased demand in 2020, refinery CO 2 emissions saw a 15.4% year- on-year decrease. The most significant part of this decrease came from process unit emissions (each of which play a role in the overall process of converting crude oil into finished petroleum products) which decreased by 24.2% in 2020. Due to this large decrease in process unit emissions, the overall increase in such emissions from 2000 has fallen from 26.4% between 2000 and 2019 to just 0.4% from 2000 to 2020. Large combustion plant (LCP) emissions, which decreased by 8.6% in 2020 have decreased by 33.8% since 2000. Overall transport sector emissions decreased by 19.2% in 2020, resulting in an overall decrease of 25.4% since 2000 to 97.7 MtCO 2 . The vast majority of transport sector emissions continue to come from the road transport segment, although the largest year-on-year decrease in emissions, of 60.1% was seen in the aviation segment due to prolonged travel restrictions. Road, rail, and shipping CO 2 emissions decreased by 19.1%, 22.2%, and 12.8%, respectively, in 2020.
