Biden's new climate orders to include pause on federal oil and gas leasing: sourcesFILE PHOTO: Pump jacks operate in front of a drilling rig in an oil field in Midland, Texas U.S. August 22, 2018. Tribal lands, which host significant reserves of oil and gas, were not included in the Interior Department order, and will not be included in Biden’s executive order either, according to the sources. Biden’s other climate-related executive orders on Wednesday will include beefing up the use of climate science in policy decisions and setting up an international summit on climate change for April, according to a memo seen by Reuters last week. Advocates for the pause say the federal leasing system is in need of reforms to address its impact on climate change and ensure that taxpayers get fair returns. Of the 26 million acres of federal lands under lease, about half are currently producing oil and gas, according to Bureau of Land Management data from fiscal year 2019.
