In 1994, the Institute for Ecological Economy Research (IÖW) and the business network ‘future’ carried out the world’s first ranking of corporate environmental reports. It evaluates the content and communicative quality of the sustainability and environmental reports of Germany’s 150 largest corporations. The criteria, which served as the basis for the evaluation, have been continuously developed as the project has been repeated (which occurred in the years 1996, 1998, 2000 and 2005). In 2007, IÖW and ‘future’ carried out the sixth Ranking of the environmental, CSR, and sustainability reports of Germany’s largest corporations.
