Judges won’t block Biden’s ‘social cost of carbon’ policy

WASHINGTON (AP) — The Supreme Court on Thursday allowed the Biden administration to use a higher estimate, disputed by Republican-led states, to calculate the harm to people and the environment from greenhouse gas emissions. Greenhouse.

The judges made no comment as they declined to reinstate an order from a Louisiana federal judge that had prevented the administration from focusing more on potential harm from greenhouse gas emissions during the creation of rules for polluting industries.

The approach uses the “social cost of carbon” to calculate future climate damage to justify tighter restrictions on fossil fuels, transport and other industries.


The federal appeals court in New Orleans stayed the order, and Louisiana led nine states to ask the High Court to intervene.

The judges’ refusal to do so allows the administration to use an interim standard of damages of $51 per ton of carbon dioxide emitted while it works to update and possibly increase the cost. per ton. The $51 figure was used by the Obama administration before the Trump administration reduced it to $7.

By itself, the estimate does not impose new requirements, but it could be used to justify stricter rules. States would be free to challenge any new regulations.
