„I am a realist“

In a couple of days the high level meetings at the Rio+20 conference, the United Nations Conference on Sustainable Development, are going to start. What can be expected from these debates? What could be the outcome of Rio+20? We asked Barbara Unmüßig, head of the German Heinrich Böll Foundation. She took part in the first „Earth Summit“ in Rio de Janeiro in 1992 and has been following the international debates closely ever since. According to her it’s best to „be a realist“ – and not to expect too much.
