The latest step in a woman’s legal fight over a Surrey oil drilling permit has concluded.

Sarah Finch’s lawyers told the Supreme Court that planning authorities should have considered the climate impacts of burning the oil, not just extracting it.

Surrey County Council said it followed planning law.

The case could spell the end of new UK fossil fuels projects when judges reach a decision in the coming months.

The climate impacts at the heart of the case are ‘downstream emissions’ – the greenhouse gas emissions released when the oil will be burned. Ms Finch says these are estimated to be 10 million tonnes over 20 years.
