Unlikely to pass
The bill currently lacks Republican support and focuses on climate research, which often faces political hurdles in a divided Congress.
Key Points
The bill requires the EPA to start a new grant program to study ground-level ozone. This is a type of gas that forms near the Earth's surface and can affect the climate and human health.
Researchers will look at how this ozone affects global temperatures and causes heat stress in specific areas. They will also study how it leads to crop losses for farmers and harms the health of forests.
The program will provide money to colleges and national labs to build better tools for tracking air quality. This includes setting up more monitoring stations in rural and farming communities that are often ignored.
The EPA will use the research to create a major report within four years. This report will suggest new ways to reduce the chemicals that create ozone and estimate the costs and benefits of those actions.
Congress would provide over 10 million dollars each year from 2027 to 2029 to pay for these studies. A final 1 million dollars would be used in 2030 to finish the official report and share the findings with the public.
