The Tropospheric Ozone Research Act of 2026 aims to create a research program focused on understanding and addressing the impacts of tropospheric ozone on climate and the environment. The main objective is to gather scientific data that can help mitigate the negative effects of this pollutant, which is known to contribute to global warming and harm public health and ecosystems. The key provisions of the Act include the establishment of a competitive grant program managed by the Environmental Protection Agency (EPA).
