UGA - Umweltgutachterausschuss / German EMAS Advisory Board

The German EMAS Advisory Board (UGA) supports the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety in implementing EMAS in Germany and promoting the dissemination of EMAS. Its tasks, members and responsibilities are regulated in the Environmental Audit Act. Several working groups support the plenary meeting (2-3 per year). They prepare topics and projects in specific meetings for the final decision of the plenary meeting.

VNU is represented with its environmental verifyer as of the first nomination period in 1995. Additional VNU members represent industry or environmental associations. Representatives and their alternates are nominated in the IX. period for 3 years (2020-2022).
