The green light to develop one of the largest untapped oil and gas fields in british waters. Rosebank lies in the north sea, about 80 miles west of shetland. Experts say it contains about 350 Million Barrels of oil. Production could start in 2026, with extraction continuing until at least 2030.

There would also be natural gas, with about 44 million cubic feet produced per day during the projects lifetime. The Energy Secretary Clare Coutinho says. The news has not gone down well with climate campaigners. Heres tessa khan, executive director of uplift, a group that has been working to stop Rosebank Being opened up for oil and gas production.
