The Rio+20 summit on promoting jobs, clean energy and a more sustainable use of our planet's resources closed today after three days of talks. During the summit, the role of Earth observation in sustainable development was highlighted.

In 1992, a blueprint to rethink economic growth, advance social equity and ensure environmental protection was adopted at the Earth Summit in Rio de Janeiro, Brazil.

Now, 20 years later, the Rio+20 Summit brought participants from governments, the private sector, non-govermental organisations and other stakeholders once again to Brazil to evaluate the progress being made.
