Twelve AGs Filed Amicus Brief Supporting Use of Social Cost of Carbon Metric

New York Attorney General Letitia James led 12 states in filing an amicus brief on whether federal agencies can consider the metric known as the social cost of greenhouse gas emissions in rulemakings. In February 2022, a federal court in Louisiana ordered the administration not to consider it. In their amicus brief, the states argued that the lower court’s order was based on a misunderstanding about how the metric is used. The coalition urged the court to reverse and vacate the injunction. The Fifth Circuit has stayed the injunction and recently, the Supreme Court denied a request to lift that stay, which means that the administration is currently authorized to consider it.
