How can sustainability assert itself as a benchmark for businesses, consumers and society? What needs to happen to change the lifestyles of millions of people sustainably? What makes sustainability truly irresistible?

In the book GreenSmartSexy, which I’ve published in autumn 2009 together with Martin Kleene, we offer more than 50 ideas for businesses, institutions and all those who want to change our society sustainably.

In order to make our book a compelling product, we commissioned the award-winning graphic designer Mirko Borsche to design the entire book. The climate-neutral production of the book was enabled by Jürgen Schmidt, founder of memo AG.

The book is available on Amazon for 12,95 € or here, at our publishing house.

And for those who are in a hurry, here’s a PDF ready for download.
