Since January 2026, EPA has spurned decades of agency practice and an enormous scientific record by declining to incorporate in its regulatory analyses any estimates of the impact of particulate matter and ozone on human health. We have launched a new calculator that uses EPA-produced data on health effects and the monetized damages of these effects to help fill this void. During this webinar, we will offer a tutorial and example uses cases for the calculator, discuss the ramifications of EPA's decision to omit particulate matter and ozone estimates from its analyses, and respond to audience questions.
