The Full Form of EWG is Environmental Working Group.

The Environmental Working Group (EWG) is an American activist group that specializes in research and advocacy in the areas of agricultural subsidies, toxic chemicals, drinking water pollutants, and corporate accountability. EWG is a nonprofit organization (501(c)(3)).

Founded in 1993 by Ken Cook and Richard Wiles, EWG is headquartered in Washington, D.C. in the United States. A sister lobbying organization, the EWG Action Fund (a 501(c)(4) organization) was founded in 2002.

The accuracy of EWG reports and statements have been criticized, as has its funding by the organic food industry. Its warnings have been labeled “alarmist”, “scaremongering” and “misleading”. Despite the questionable status of its work, EWG has been influential.
