Egdon Resources has submitted an appeal against the refusal of planning permission for oil production at Bscathorpe in Lincolnshire.
The county council voted by 7 to 4 in November 2021 to refuse permission for long-term production and a sidetrack oil well.
The decision was against the recommendation of planning officers but followed 200 local objections to the scheme and a petition with more than 1,800 signatures.
Opponents included the local MP and justice minister, Victoria Atkins, as well as Lincolnshire Climate Commission, the countryside charity CPRE, Lincolnshire Wildlife Trust and five parish councils closest to the site.
Egdon has estimated the Biscathorpe site could generate almost four million barrels of oil.
A report by Friends of the Earth and the New Economics Foundation concluded that Biscathorpe oil would generate 1.7 million tonnes of carbon dioxide equivalent. Opponents have said the carbon emissions in one year would be nearly ten times the council’s entire carbon saving target for 2023.
