Federal agencies would be most directly affected. They would no longer be able to use the "social cost of greenhouse gases" metric in their analyses for evaluating regulations, projects, and other decisions. This change could alter how they assess the benefits and costs of proposed actions related to energy, infrastructure, and environmental policy.

Industries and businesses, particularly those that emit greenhouse gases (like energy producers, manufacturers, and transportation companies), could also be affected. Regulations impacting these sectors might be developed without considering the broader societal costs of their emissions, potentially leading to different regulatory outcomes. The general public and the environment could be indirectly affected by policies that no longer factor in the estimated monetary damages from greenhouse gas emissions, influencing the strictness of environmental protections and the long-term economic and environmental impacts associated with climate change.
