EWG

The Environmental Working Group (EWG) is an American nonprofit organization focused on environmental and public health issues. Founded in 1993 and based in Washington, D.C., EWG conducts research, advocacy, and public education to help consumers reduce exposure to potentially harmful chemicals and to push for stronger environmental protections.

The group maintains consumer guides such as the Skin Deep cosmetics database, the Shopper’s Guide to Pesticides in Produce, and the Tap Water Database. It publishes reports and indexes on chemical hazards, and it tracks regulatory developments at the federal and state levels. EWG’s work includes policy analysis, lobbying, and collaboration with other health and environmental groups.

EWG’s research is widely cited by media, lawmakers, and advocacy organizations. It aims to translate scientific data into practical guidance for households and policymakers.

The organization has faced criticism from some scientists and policymakers who argue that its hazard-based assessments may overstate risks or fail to account for actual exposure. EWG defends its methods, arguing that hazard information helps consumers make informed decisions and that their issues are addressed by chemical safety reform.

EWG is a nonprofit organization guided by a board of directors and staffed by researchers, scientists, and communications specialists. It relies on donations from individuals and philanthropic foundations.
