Federal climate rollbacks would make offshore wind less competitive against established energy sources

Long-term shifts in the Earth's climate driven by greenhouse gas emissions, and the political response to them in the United States. Covers emissions rules, disaster spending and adaptation, a field where federal policy has reversed direction with each change of administration.

American policy and political argument over climate, conservation, pollution, public lands and the environmental regulation of industry. Much of it is fought through federal rulemaking and the courts rather than legislation, which makes each administration's regulatory posture the decisive variable.

State Attorney General Rob Bonta challenged the Trump administration's September 28, 2026, efforts to roll back climate regulations affecting offshore wind projects and clean-energy funding. Bonta said the dispute over greenhouse-gas regulations could reach the Supreme Court.
