Keeping track of our changing environment : from Rio to Rio+20 (1992-2012)

Abstract

This publication was conceived with the idea of showing how the planet has changed in two decades—just twenty years—since decision-makers met at the United Nations Conference on Environment and Development in Rio de Janeiro. To relay this information in a compelling and succinct manner, environmental and related trends are charted and presented using globally-aggregated (and mainly statistical) data sets collected by international agencies, research bodies and other official entities.
