(Reuters) - Upcoming federal oil and gas lease sales will be delayed as the Interior Department figures out how to weigh the climate impact of those sales without using a key tool for measuring those risks, according to a court filing issued on Saturday evening.
The length of the delay was not specified, but it stems from a Feb. 11 decision by a Louisiana federal district court judge that blocked the Biden administration from using the "social cost of carbon" - an interim estimate of $50 per ton of greenhouse gases emitted - to factor the risks of climate change into federal decision-making for permitting, investment and regulatory issues.

That decision has complicated the Interior Department's efforts to comply with a separate court decision by a D.C. federal district court judge in January which invalidated the results of an oil and gas lease sale in the Gulf of Mexico because the department failed to properly account for the auction's climate change impact.
“Certain activities associated with its [Interior's] fossil fuel leasing and permitting programs are impacted by the February 11, 2022, injunction in Louisiana v. Biden," the Department of Justice filing said.
