To streamline emissions data, the U.S. Environmental Protection Agency’s (EPA) Risk-Screening Environmental Indicators (RSEI) is a modelling tool that helps policy makers, researchers, and communities explore data on releases of toxic substances from…

Estimating and monetizing public health benefits from reductions in emissions can be a complicated process requiring expertise in air quality modeling, health impact valuation and the monetization of health benefits. Because of this, researchers,…

Structures such as buildings and roads, absorb and re-emit much more of the sun’s heat than do natural landscapes such as forests and bodies of water. Urban areas with highly concentrated structures become “islands” of higher temperatures compared to…

The Environmental Protection Agency (EPA) has been collecting greenhouse gas emissions data through the Greenhouse Gas Reporting Program (GHGRP) from approximately 8,000 emitters—including power plants, oil and gas producers, and manufacturers—since 2010…

More than 140 unregulated chemicals contaminate public water supplies in 42 states. The risk to consumers is unclear because researchers haven’t figured out the threshold for when they cause harm. To weigh regulatory options, the Environmental Protection…
