Arrived in Sao Paulo on Sunday morning and then was immersed in several days of meetings with the Instituto Ethos Advisory Board. One of the things we discussed with Ethos founder Oded Grajew was the possibility of organising a parallel conference in 2012 to mark the twentieth anniversary of the 1992 UN Earth Summit in 1992. Later we all cascaded into the annual Ethos conference. I did a couple of sessions, chairing one with Pavan Sukhdev of Deutsche Bank and UNEP, Otto Scharmer, of MIT, who focuses on what he calls ‘Theory U’, and Vania Somavilla, who is Director of Environment and Sustainability at the mining company Vale. Will try and track down and post some photographs – I took very few this week. Alejandro (Litovsky) and I also did a session to launch our new report, The Biosphere Economy.
