20 years ago, the Rio Summit met to define ways to foster sustainable development and raised lots of hopes all over the world. 20 years on, the strong historical message delivered by the young Severn Suzuki has not been fully heard and much remains to be done to preserve our natural capital.In June this year, the Rio+20 Summit will be the opportunity to set the sustainable development agenda for the next 20 years. One of the key themes of the summit will be how to define the 'green economy'. Will land protection be duly taken into consideration? Will the need for ocean governance be finally addressed? Will concrete measures and targets be adopted? How will environmental governance be framed? Will the EU play a key role in achieving a successful outcome? The questions are numerous and civil society is pushing for strong commitments.
