BILLINGS, Mont. (AP) — U.S. government regulators for the first time will analyze greenhouse gas emissions from federal oil and gas lease sales on a national scale as the Biden administration steps up efforts to address climate change. The announcement Friday came as officials released a report saying fossil fuel extraction from federal lands produced more than 1 billion tons of greenhouse gases last year. That’s about one-fifth of all energy related emissions. President Joe Biden campaigned on promises to end new drilling on public lands to help address climate change. But his attempt to suspend new lease sales was blocked by a federal judge in Louisiana.
