Dear Mr. Regan,

As religious organizations from diverse faith traditions, we are united in our commitment to working towards a world in which God’s sacred earth, our communities, and all individuals can flourish. At the most basic level, this requires clean air to sustain us.

Currently, more than four in ten Americans live in places where the air they breathe is harmful to their health.1 An estimated 100,000 deaths each year in the United States can be attributed to human-caused emissions of soot pollution, also known as particulate matter or PM 2.5.2 A dangerous and deadly pollution, soot has devastating public health impacts that can lead to premature death, shorter life expectancy, greater rates of diabetes and lung disease, adverse health effects on children,3 premature births, increased stillbirths and low birth weight in newborns.4 These impacts are felt disproportionately by low-income communities and communities of color, largely due to historic redlining and ongoing environmental injustices.5

The Environmental Protection Agency’s (EPA) proposed soot standard is an important step forward in regulating PM 2.5 pollution. To correct environmental injustices and protect the health of God’s earth and all communities, the EPA should set the annual pollution standard at the most stringent level under consideration, to 8 micrograms per cubic meter,6 which according to one study would save an estimated 19,600 lives from PM-attributable deaths.7 The EPA
should also tighten the daily standard to 25 micrograms per cubic meter to protect those who are most vulnerable.

The EPA has an opportunity to save thousands of American lives now and for generations to come. As people of faith who recognize and uplift the inherent dignity of all individuals and the simple right to breathe without risk of harm, we urge the EPA to issue stricter standards and help correct environmental injustices, promote public health, and protect God’s Creation.
