Republican efforts to stall President Joe Biden’s climate agenda are slowly beginning to take shape. In March, a coalition of 12 Republican state attorneys general filed a lawsuit challenging Biden’s executive order creating a working group to establish a metric for the “social cost of carbon.” Led by Missouri’s attorney general, Eric Schmitt, the lawsuit charges that the order is an “enormous expansion of federal regulatory power” and that such cost calculations are “inherently speculative, policy-laden, and indeterminate” and should instead be undertaken by Congress.
