The Oil and Gas Association published analysis in May 2020, comparing the carbon intensity of United Kingdom Continental Shelf gas with imported liquified natural gas and pipelined gas:

This analysis shows that gas extracted from the United Kingdom Continental Shelf has an average emission intensity of 22 kgCO2e/boe; whereas imported liquified natural gas has a significantly higher average intensity of 59 kgCO2e/boe. The process of liquefaction, combined with the emissions produced by the transportation and regasification of the liquified natural gas once in the United Kingdom, is responsible for the higher emissions intensity.
