Summary

EPA grant program for tropospheric ozone research funds competitive studies on how tropospheric ozone and its precursors affect climate, crops, ecosystems, and health. The program requires public data sharing and international collaboration.

Show full summary
  • Colleges, National Laboratories, and qualified nonprofits can compete for grants to study ozone's climate and environmental effects. The program sets aside up to $10.0 million per year for grants in 2027–2029.
  • Farmers and forest managers gain targeted research on crop losses and declines in forest and ecosystem productivity from elevated ozone to inform mitigation and adaptation.
  • The public and policymakers get open monitoring data and an EPA findings and recommendations report to Congress within 4 years to guide precursor-specific mitigation and monitoring improvements.

*Authorizes $32.5 million for 2027–2030, including about $30.0 million for grants and $1.5 million for program oversight across 2027–2029 plus $1.0 million for 2030 reporting, which would increase federal spending.*

Grants for ground-level ozone research

If enacted, the EPA would set up a competitive grant program to study tropospheric (ground-level) ozone and its chemical precursors. The program would be authorized $10.5 million for each of fiscal years 2027–2029 and $1.0 million for fiscal year 2030; of each $10.5 million for 2027–2029, $10.0 million would fund grants and $0.5 million would fund program oversight. Colleges, National Laboratories, and nonprofit research groups with air quality or climate expertise could receive grants. Monitoring data funded under the program would be made public, grantees would post annual public reports, and EPA would deliver a public report to Congress within four years. EPA would start the program within 90 days after money is appropriated and must select grant recipients within 180 days after the program is established.
