Mark, I have to say that this is a wonderful question you pose. Very bluntly, you will not regulate yourself into sustainable development. Sustainable development is more than just regulation. We have these legal impact assessments in place, but it would be more important, I think, to create a notion in society that with sustainability there's something in it for the ordinary person. That comes with the huge understanding that we have of the impact on food of sustainability and of jobs created by sustainability.
That is why I think creating wealth is a prerequisite, as is keeping it within the planetary boundaries. It all comes down to what wealth is and what “wealthy” means to you. The German green economy is prospering and is an increasing economic part of Germany. That is where people have put their trust.
You mentioned Greece. I just came back from Athens where, together with the National Bank of Greece, I introduced the Greek sustainability code. It is for companies in Greece, and it's about creating trust and prosperity. That's the way forward.
