The document announces a side event taking place during the Rio+20 conference to discuss approaches for reliably measuring progress towards sustainable development and a green economy beyond traditional GDP indicators. The event will feature presentations from experts at organizations such as the European Environment Agency, Global Footprint Network, and OECD on indicator-based assessments of environmental state, the ecological footprint, and reflecting human well-being. A panel discussion will be moderated by the director of the Charles University Environment Center on making best use of "Beyond GDP" indicators in policy decisions.
