Britain's oil and gas rigs most polluting in North Sea, says report

Release of CO₂ from UKCS rigs was much greater than Norwegian and Danish regions

Britain's oil and gas rigs are the most polluting in the North Sea oil basin, according to industry data, with enough unwanted gas burned off every year to heat a million homes.

Oil rigs in the UK continental shelf (UKCS) released 13.1m tonnes of carbon dioxide emissions into the atmosphere last year, according to data from Rystad Energy, significantly more than those from the Norwegian and Danish regions of the North Sea, which produced 10.4m tonnes and 1.4m tonnes of CO₂ respectively in the same year.
