Environmental issues play a central role in urban planning. However, in emerging megacities, infrastructure growth often takes precedence over the environment. This is just one of the key findings of a survey of 522 decision makers from 25 global metropolises. The research project, which is unique worldwide, was conducted by the two research institutes GlobeScan and MRC McLean Hazel and supported by Siemens. Experts presented the results of the research in a press conference at the World Economic Forum in Davos for the first time. Solving transportation issues has the highest priority in the cities surveyed, and air pollution is seen as the main environmental issue. Survey respondents believe that the private sector should play a major role in city infrastructures like energy, water, transportation and health care: more than 70 percent of them believe that public private partnerships are a promising approach.
