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.

Paramount Skydance Corporation

Colorado Attorney General Phil Weiser joined a coalition of 12 attorneys general in settling a lawsuit against Paramount Skydance Corporation over its merger with Warner Bros. Discovery, which the states alleged would harm competition by lowering film output and raising prices. The settlement includes a five-year commitment to increase film output, a $1.5 billion investment in domestic production, a $47.5 million worker fund, and an independent monitor. This is an antitrust/competition enforcement action, not a privacy enforcement action, despite the extraction schema's privacy focus.

CO

Credit Acceptance Corporation

$694.0M

Colorado and 40 other states entered into a settlement with Credit Acceptance Corporation (CAC), one of the nation's largest subprime auto lenders, resolving allegations that CAC originated car loans it knew or should have known consumers could not afford and that it failed to reasonably prevent dealers in its network from deceptively 'packing' Vehicle Service Contract and GAP add-on products into CAC-financed purchases. The settlement provides $694 million in cash and debt relief to consumers plus an additional $15 million to the attorneys general, and imposes injunctive reforms including loan 'off ramps,' enhanced pre-purchase and pre-loan disclosures, dealer monitoring, and a seven-year price cap at 109% of retail book value. Note: this is a consumer-lending enforcement action, not a data privacy matter; the 'dark_patterns' category is the closest available fit for the deceptive add-on sales allegations.

Sares Regis Group

$30K

Colorado Attorney General Phil Weiser announced a settlement with Sares Regis Group, a Denver-metro property management company, after an investigation found it told prospective tenants that rental subsidies and housing vouchers were not accepted at its properties, in violation of the Colorado Anti-Discrimination Act and the Colorado Consumer Protection Act. Under the settlement, the company must adopt written source-of-income policies, train leasing employees, submit a compliance report to the AG's office, and refrain from misrepresenting its voucher acceptance, and it pays $30,000 to the Housing Rights Initiative. Note: this is a fair-housing enforcement action, not a privacy matter, so no privacy violation taxonomy categories apply.
