The United Kingdom is allowing a proposed gas drilling project in the North Sea to move forward, a major reversal in the country’s climate change policy, which previously banned new fossil fuel drilling in the region.

The sign-off on the project, known as Jackdaw, had been expected for months, as new Prime Minister Andy Burnham faced intense pressure from the fossil fuel industry in the U.K. and from the Trump administration to overturn the North Sea drilling ban.
