GreenLaw will be posting reports, observations and reflections from our Pace Law contingent in Rio de Janeiro, Brazil for the Rio+20 conference – the 20th anniversary meeting of the 1992 Earth Summit, now called the Conference on Sustainable Development. In addition to Professors Nick Robinson and Ann Powers, a number of alumni and current students are in Rio in a variety of roles – experts, negotiators, and other participants. Stay tuned on GreenLaw for reports from the preparatory committee (PrepComm) meetings and side events.
