In 2020, CEH began an exciting collaboration with the national CityHealth initiative to develop a set of environmentally preferable purchasing (EPP) policy recommendations—for furnishings, foodware, and cleaning products—that cities can adopt to protect the health of millions of city workers and residents. These products—which often contain a host of harmful chemicals that contribute to indoor air contamination—can pose serious health threats to the average American, who spends 90 percent of their time indoors. One significant way local governments can improve human and environmental health is through the products they buy. Cities have tremendous purchasing power, and when multiple cities specify safer products, their combined demand sends a powerful signal to the market. The transition to safer products also reduces the amount of toxic chemicals that can contaminate our environment throughout the product lifecycle: from manufacturing, to use, and eventually, to disposal. The ongoing partnership, which now covers 75 of the largest U.S. cities, will support more local governments in creating healthier environments for workers and residents. This is especially important for people in low-income communities and communities of color who are burdened by higher levels of exposure to hazardous chemicals. Together we hope that CEH and CityHealth’s work with cities on the new EPP policy recommendations, will create important benefits for both human health and the environment for decades to come.
