Barcelona’92 developed an urban regeneration of abandoned areas introducing a variety of environmental measures. At the same time, ecological issues gained global social and political awareness. One month before the 1992 Olympics, the “Earth Summit” in Rio decreed conclusions that were adopted by the IOC in the next years. However, the management of Barcelona’92 also induced the environmental and sustainable principles of the Olympic movement. This book analyses this influence and looks at how the ecological dimension of Barcelona’92 was communicated. The Rio’s influence motivated communication projects like the exhibition ‘Beloved Earth’ during the Games, pedagogical activities at the Youth Camp, the Earth Pledge mural in the Olympic Village and the plantation of a number of trees equivalent to the amount of paper consumed.
