A coalition of conservative and free-market groups is lobbying lawmakers to amend a major defense policy bill that would ensure climate change is no longer part of the Pentagon’s planning and operations going forward.

“These climate programs and policies have nothing to do with the mission of the United States’ Armed Services,” said a letter sent to House members by the coalition on Wednesday. “In fact, many of these programs and policies are likely to undermine military readiness by diverting scarce resources to such things as helping state and local governments to ‘go green,’ meeting targets for reducing carbon dioxide emissions, meeting a variety of green energy quotas, meeting fleet requirements for low and zero emissions vehicles, and incorporating climate resilience and preparedness as principal aims of land and water management.”
