From 2009 to 2013 he was a Member of the Bundestag, the German federal parliament in Berlin, and served as the Greens’ speaker on climate policy.

Besides of his professional and political work he enjoys his family (with two kids and one grandchild), served on the Board of Greenpeace Germany, and served on the Executive Committee of the German League for Nature, Animal and Environment Protection (Deutscher Naturschutzring, DNR), a network of 87 environmental organisations in Germany.

Preserving our Earth in a condition that’s hospitable for future generations of humans and all other creatures has always been my mission.

Legal environmental action has proven to be the sharpest weapon in the quest for a sustainable future and I hope that we can support Germany, the largest country of the EU, to become a leader in environmental and climate protection again.
