EPA eases ozone rules for Salt Lake
The Trump EPA is proposing to extend the same foreign-pollution logic it used for Phoenix to the Salt Lake City area, saying ozone standards would have been met without emissions transported from outside the United States. Lee Zeldin said pollution from Mexico and Asia should not trigger stricter nonattainment penalties, which could spare the region tougher vehicle, factory and power-plant rules. Environmental groups and air-quality experts argue the Clean Air Act does not let distant overseas pollution replace local emissions cuts.
Why it matters
It could weaken ozone enforcement in major Western metros and set a new precedent for how imported pollution is treated under the Clean Air Act.

The New York Times coverageState insurers order climate-loss data sweep
State insurance regulators, through the NAIC, are requiring insurers to turn over internal claims and loss records for wildfires, storms and other perils by ZIP code as part of the most detailed review yet of the property-insurance market. Florida Insurance Commissioner Michael Yaworsky is leading the effort, which covers more states and more policy types than a 2024 data call and is expected to capture about 98% of the market in most states. Regulators plan a public report in 2027, while some states have opted out and advocates are pressing for raw-data transparency.
Why it matters
The data could show how climate risk is reshaping insurance prices and availability, and it may influence future regulation and resilience policy.

E&E News by POLITICO coverageChina tightens fossil-fuel climate oversight
China issued guiding opinions on 22 April urging local governments to "strictly control fossil-fuel consumption," then followed with new provincial evaluation criteria that include clean-energy consumption and limits on coal and oil use. Carbon Brief says the measures came from the top of the political system and reinforce accountability around climate targets. The briefing also noted that China's clean-energy grid capacity topped 2,400 GW by March even as first-quarter solar additions slowed to 41 GW and officials warned an El Niño pattern is likely around May.
Why it matters
It signals stronger political pressure on provinces to curb fossil-fuel use even as weather and power-system stress could complicate the transition.

India solar output rose 24%
Q4 FY26 generation reached 48.9 billion units, but about 27 GW of solar was curtailed, showing grid bottlenecks even as peak demand hit a record 256 GW.
WORTH NOTING
Chinese solar exports jumped 99% in March
Carbon Brief said the surge reached 68 GW and was driven by the April 1 export-rebate cutoff, lower silver costs and strong overseas demand tied in part to Middle East conflict.

Colombia fossil-fuel summit centered on financing
The 56-country meeting ended without binding commitments but created follow-on work on financing and labor transitions, with the next conference planned for Tuvalu.
Still unclear
OPEN QUESTION
Will courts accept the EPA's imported-smog rationale?
The answer will determine whether the new ozone-relief approach can survive legal challenge and spread beyond Phoenix and Salt Lake City.
OPEN QUESTION
Will regulators publish the raw insurance ZIP-code data?
Public access would decide how useful the new NAIC review becomes for consumers, researchers and policymakers.
