On April 1, the Institute of Public and Environmental Affairs and the Natural Resources Defense Council’s Beijing office released their joint report, Pollution Information Transparency Index (PITI) 2012. The study praised China’s work on publishing data on air pollution but urged the country to improve its disclosure system on air, soil, and water pollution. The report also advocated for the issuing of information online and in real-time. Representatives from the two organizations also suggested China mirror disclosure systems set up by the U.S. and by the European Union.
