The Bureau of Ocean Energy Management (BOEM) announced that they are canceling the Record of Decision for the Gulf of Mexico Outer Continental Shelf Oil and Gas Lease Sale 257. This decision is in response to Executive Order 14008, which pauses new oil and gas leasing on public lands and offshore waters until a comprehensive review is completed. The lease sale was initially planned to occur on March 17, 2021, but is now halted. BOEM may consider the lease sale again after the review and could issue a new decision in the future.
Simple Explanation
The government decided not to go ahead with a plan to let companies look for oil in the Gulf of Mexico right now, because they're checking how it might affect the environment.
