Scores of Labour MPs have urged the prospective prime minister Andy Burnham to rule out the “tin-eared” and “deluded” development of the Rosebank oilfield in the North Sea, which new research indicates would produce as much carbon dioxide as the UK does in 10 months.

Estimates seen by the Guardian show that Rosebank, which mainly contains oil, would produce about 250m tonnes of CO₂ over its lifetime. That is the equivalent of about 70% of the UK’s annual emissions.
