The Blue Angel (Blauer Engel) is a German certification for products and services that have environmentally friendly aspects.

The certificate has been awarded since 1978 by the Jury Umweltzeichen, a group of 13 persons from environment and consumer protection groups, industry, unions, trade, media and churches.

After the introduction of Germany's Blue Angel in 1978 as the first world-wide environment label, other European and non-European countries followed this example and introduced their own national and supra-regional environmental labels. The common goal of these labels is to inform consumers about environmentally friendly products thereby giving global support to product related environmental protection.

In 1994 some countries co-operated in developing the Global Ecolabelling Networks (GEN) - a non profit interest group composed of ecolabel organisations throughout the world.
