"The Supreme Court will not take up a lawsuit led by the state of Missouri that sought to block the Biden administration’s “social cost of carbon” measure.

The court denied a writ of certiorari Tuesday in the case, Missouri v. Biden, without further explanation. In the case, 11 Republican-led states, guided by Missouri Attorney General Andrew Bailey (R), challenged the formula used by the administration to determine the financial costs associated with greenhouse gases, which are considered the primary cause of climate change.

After the Trump administration significantly slashed the cost measure to around $1 per metric ton, the Biden administration increased it to around $51 — using the Obama administration’s measure adjusted for inflation."
