I met Jonathon 20 years ago this year. At about this time. At an incredible building in Austria where the Sound of Music was filmed. Jonathon has lead on sustainability from the beginning. From when the first roots of the "green" movement began to poke through. This shows extraordinary foresight and bravery. He has both. This bravery was supremely evident when he went on anachronistic buffoon Jeremy Clarkson's TV chat show and not only held his own but destroyed Clarkson's arguments. A joy to watch.

We talk about many things including what it feels like now that the world has caught-up with his thinking.

This conversation covers the first part of his career and as we were in danger of a) Having too much of a good time and b) Going on too long; we have arranged to do a second part.

There are some lovely gems in here and Jonathon's warmth radiates through.
