The Promise of Environmental Justice Screening Tools in Maryland and Beyond

Since President Joe Biden assumed office, environmental justice has been at the front and center of his administration. One key initiative: developing better mapping tools to identify communities that may bear a disproportionate burden of toxic pollution and climate change impacts. Biden’s environmental justice (EJ) plan emphasizes the value of these tools and the need to improve them.

The U.S. Environmental Protection Agency’s (EPA) current tool — known as EJSCREEN — dates to 1994, when President Bill Clinton issued an executive order instructing federal agencies to collect, maintain, and analyze information on environmental and human health risks borne by low-income communities and people of color.

The EPA published EJSCREEN in 2015. It integrates demographic data (such as percent low-income, under the age five, over age 65, etc.) and environmental pollution measures at the block group or census tract level nationwide. The mapped data provide a visual of a community’s estimated pollution burden.

Though widely used by researchers and advocates, EPA EJSCREEN is not without faults.

A geospatial map, of course, is only as good as the data it uses. Unfortunately, the national air quality monitoring network is underfunded and outdated, and the devices have been found to routinely …

When California adopted its first-in-the-nation regulations requiring truck electrification on June 25, the state took a step (or drove a mile) toward reducing pollution in the nation's most vulnerable communities. The new regulation exemplifies a key feature of California's approach: its integration of climate goals, clean air goals, and, at least in this case, environmental justice goals.

According to the press release from the California Air Resources Board (CARB), trucks in California contribute 80 percent of the state's diesel pollution and 70 percent of its smog-causing pollution while constituting less than 7 percent of registered vehicles. The rule's environmental assessment explains that particulate matter from diesel engines is responsible "for approximately 60 percent of the current estimated cancer risk for background ambient air." These risks are highest near freight hubs, including "ports, rail yards and distribution centers." And these areas, in turn, are often in …

Prompting rage by President Trump, California and several carmakers entered into a voluntary agreement on carbon emissions from new cars that blew past the administration's efforts to repeal existing federal requirements. Last week, the Trump administration slapped back at California. Although there's been a lot of editorializing about that response, I've seen very little about the legal dimensions of the administration's actions. I'd like to shed a little bit of light on those.

The administration took two separate actions. First, the Department of Transportation and EPA sent a letter arguing that California's action appeared to violate the federal statutes governing CAFE (fuel efficiency) and emissions standards for new vehicles. Second, the Justice Department opened an antitrust probe of the car companies themselves. How strong are the government's legal positions?

Let's start with the DOT/EPA letter. The Clean Air Act and the …
