Colorado-led coalition challenges EPA power plant emissions rollback

United States Environmental Protection AgencyOctober 1, 2026Colorado Attorney General

Summary

Colorado Attorney General Phil Weiser joined a multistate and local coalition challenging the EPA’s repeal of greenhouse gas limits for many coal- and gas-fired power plants. The coalition seeks to have the repeal struck down and the protections restored, and separately notified the EPA of its intent to sue over regulation of emissions from existing gas plants; no penalty or final court remedy is reported.

Remedy

The coalition asks the court to strike down the EPA’s repeal and restore the pollution limits. It also filed a notice of intent to sue regarding the EPA’s failure to regulate greenhouse gas pollution from existing gas-fired power plants; no remedy has been imposed.

Contract Impact

Although this is an environmental regulatory action rather than a privacy enforcement, in-house teams should review supplier, power-purchase, facilities, and manufacturing agreements for representations that operations comply with applicable emissions limits and environmental permits, along with obligations to monitor and report greenhouse gas emissions. Check change-in-law and regulatory-cooperation clauses for how costs and compliance duties are allocated if emissions standards are restored or changed, and review audit, records-access, and environmental indemnity provisions for adequate coverage of supplier reporting failures or noncompliance.
