Anniversary booklet, english version

Flyer 40 Jahre Blauer Engel
In this anniversary booklet, we give you a glimpse behind the scenes:

...How everything began in the 1970s, when spray cans still contained CFC and the Club of Rome made the world aware of the “limits to growth“. What’s more, discover how we are shaping the environmental label to be future-proof and how we have our sights set on the next generation.
