In a significant moment for U.S. climate policy, the Senate voted down a resolution aimed at nullifying the Environmental Protection Agency’s emissions rule for Indiana, marking another chapter in the ongoing debate over federal regulation of air pollution. The resolution, known as S.J. Res. 60, was introduced by Senator Sheldon Whitehouse (D-RI) in September 2025, seeking to block a Trump-era rule adjustment to the Revised Cross-State Air Pollution Rule (CSAPR) Update. Despite strong support from Democrats, the motion failed along largely party lines, with a vote of 47–51.
Understanding the EPA Rule in Question
The resolution targeted an interim final rule from the EPA, published in May 2025, that revised the CSAPR Update for Indiana. This rule was designed to adjust emissions allowances for the state’s coal-fired power plants and was part of broader efforts to manage cross-state air pollution, particularly nitrogen oxides (NOx), which contribute to ground-level ozone and smog.
Key changes included:
- Increasing the NOx emissions cap during the summer “ozone season” for coal-fired plants in Indiana.
- Revising emission allowances after previously announced coal plant retirements were delayed or canceled, which altered the anticipated emissions landscape.
Critics argued the adjustments could allow higher levels of pollution during a season when air quality is already under pressure, raising concerns about public health and environmental impact. Supporters of the rule cited flexibility for energy producers as necessary for maintaining reliability and avoiding unintended economic disruption.

The Congressional Review Act and S.J. Res. 60
Senator Whitehouse leveraged the Congressional Review Act (CRA) to introduce S.J. Res. 60. The CRA allows Congress to overrule certain federal agency regulations through a joint resolution, providing a mechanism to quickly nullify rules deemed harmful or overreaching.
In this instance, Democrats aimed to use the CRA to counter what they viewed as a rollback of environmental protections, arguing that the EPA’s interim final rule undermined progress on air quality standards and climate mitigation.
The Senate vote was framed as a “motion to proceed to consideration”, a procedural step necessary before debating the resolution itself. When the motion failed, the resolution was effectively killed, preventing any further discussion or potential vote on the merits of the rule.
Republicans successfully blocked the measure, emphasizing regulatory certainty for energy producers and highlighting concerns about using the CRA to undo long-standing administrative actions. The outcome reflects the broader partisan divide over environmental policy, regulatory oversight, and federal authority in shaping climate action.
Why This Vote Matters
The defeat of S.J. Res. 60 underscores several important dynamics in U.S. climate and environmental policy:
- Partisan Divide on Climate Regulation: The largely party-line vote highlights how Democrats and Republicans continue to clash over the balance between environmental protections and economic considerations in energy regulation.
- Impact on Air Quality and Public Health: Adjustments to emissions caps and allowances can directly affect air quality, particularly in industrial regions. Nitrogen oxides contribute to ozone formation, which can exacerbate respiratory issues and other public health concerns.
- Congressional Review Act as a Policy Tool: While the CRA can be a powerful mechanism for Congress to intervene in federal regulations, this vote illustrates its limitations when partisan support is insufficient.
- Long-Term Climate Implications: Regulatory changes like the CSAPR Update revisions influence not just immediate emissions but also long-term state and regional climate goals. Delays in coal plant retirements or increased emissions caps may affect broader efforts to reduce greenhouse gases and mitigate climate change.
For those tracking federal climate regulations and their implications, the S.J. Res. 60 outcome serves as a critical reminder of the ongoing interplay between Congress, federal agencies, and environmental policy.
Looking Ahead
The Senate’s rejection of S.J. Res. 60 does not mark the end of environmental debates in Washington. Energy policy, coal plant operations, and air pollution controls remain contentious issues, particularly as the United States grapples with meeting ambitious climate targets.
Environmental advocates continue to call for stricter oversight and stronger enforcement of emissions rules to protect communities and ecosystems from air pollution. Meanwhile, states like Indiana must navigate the balance between energy production, regulatory compliance, and public health considerations.
As these discussions evolve, staying informed about federal and state climate policy is more important than ever. For ongoing coverage of air quality regulations, emissions policies, and climate action initiatives, visit Sustainable Action Now’s climate section.
This vote is emblematic of the complex intersection of politics, regulation, and climate action in the U.S.—a dynamic where procedural decisions can have lasting impacts on environmental health and the fight against climate change.
