Summary

Highlight any text to annotate
This bill requires the Environmental Protection Agency to establish a competitive grant program to fund research on tropospheric ozone, which is ground-level ozone that affects climate and air quality. Universities, national laboratories, and nonprofit research organizations can apply for grants to study how tropospheric ozone impacts global and regional temperatures, crop yields, forests, and ecosystems, as well as to improve monitoring systems and climate models that account for ozone's effects. The EPA must establish the program within 90 days of receiving funding and select grant recipients within 180 days, with results reported publicly annually and a comprehensive EPA report due within four years. The bill authorizes $10.5 million annually for fiscal years 2027 through 2029 for grants and program oversight, plus $1 million in 2030 for the final report.
