The Tropospheric Ozone Research Act of 2026 (H.R. 10525) directs the Environmental Protection Agency (EPA) to establish a competitive grant program aimed at funding research on tropospheric ozone—ozone found in the Earth's lower atmosphere. The research focuses on understanding how tropospheric ozone affects global and regional temperatures, heat stress, crop yields, forest and ecosystem productivity, and human health. Key provisions include: enhancing monitoring systems, integrating data from various sources, developing improved climate models, and making collected data publicly accessible. The bill authorizes annual funding of $10.5 million for fiscal years 2027 through 2029, with $10 million allocated for grants and $500,000 for program administration. An additional $1 million is authorized for fiscal year 2030 to prepare a comprehensive EPA report summarizing research findings and recommendations.
H.R. 10525 was introduced in the 119th Congress by Deborah Ross (Democrat) and is currently listed as “Introduced”. It is classified under the Environmental Protection policy area, one of 116 bills in that area we track this Congress.
Deborah Ross is the sponsor of 10 bills in our database this Congress, so H.R. 10525 is part of a broader legislative agenda rather than a one-off proposal.
Our conflict-of-interest analysis rates H.R. 10525 2/10 (low risk), higher than 76% of analyzed bills; the average in Environmental Protection is 2.1/10.
Supporters of the bill highlight its potential to advance scientific understanding of air quality issues and its emphasis on protecting public health. They argue that increased research funding could lead to innovative solutions to combat air pollution and contribute to environmental sustainability.
Critics of the bill have raised concerns about the allocation of federal funds, questioning whether the investment in ozone research is the best use of resources compared to other pressing environmental issues. Some commentators have also expressed skepticism about the effectiveness of research initiatives in producing tangible results for air quality improvement.
The analysis of H.R. 10525, the Tropospheric Ozone Research Act of 2026, indicates no direct industry overlaps between the bill's subject matter and the top donor industries of sponsor Deborah Ross. This lack of overlap suggests that the interests of her major donors do not directly influence the legislation regarding tropospheric ozone research. Given that the bill is focused on environmental research, which typically attracts funding from a variety of sources, the absence of conflicting interests is a positive sign for transparency and accountability. Voters should be aware that while financial contributions can sometimes lead to perceived conflicts, in this case, the data shows a clear separation between donor interests and the legislative agenda.
