Red states' attempt to stop the Biden accounting metric was rejected by the Supreme Court.
The Supreme Court has dismissed a bid by red states to prevent the Biden administration from using a key climate accounting criterion in its decision-making.
The high court refused the states' request to revisit a judgement that allowed the Biden administration to utilise the climate impacts measurement in a new order issued on Thursday.
The tool in question is a set of values known as "social costs" of greenhouse gases that let the government evaluate the climate costs or benefits of its activities.
For example, the values may be used to help the government quantify the benefits of a rule that prohibits the release of climate-warming carbon dioxide into the atmosphere
as well as the additional harm that could be caused by authorising a project that emits a lot of it.
The Obama, Trump, and Biden administrations all employed societal cost values for greenhouse gases like carbon dioxide
