GEN: Structure

Internationally coordinated, locally established

Members operate independently and take various forms, including government or quasi-governmental bodies, private organisations, trusts, institutes and councils. They are ecolabelling practitioners that subscribe to the GEN mission and core values which include promotion of products with reduced environmental impact. Members are subject to regular peer reviews. At the end of 2015 there were 27 members and 4 associate members spread across some 57 countries and territories.

GEN activities are managed by a Board of Directors, and day-to-day operations are administered by a General Affairs Office and Secretariat, both reporting to the Board.

The Board meets at least twice a year.
