Switzerland leads the world in addressing pollution control and natural resource management challenges, according to the 2012 Environmental Performance Index (EPI) produced by researchers at Yale and Columbia Universities in collaboration with the World Economic Forum.
Latvia, Norway, Luxembourg, and Costa Rica round out the top five positions in the 2012 EPI, which ranks 132 countries based on 22 indicators across ten major policy categories including air and water pollution, climate change, biodiversity, and forest management.
Occupying the bottom five positions in the EPI rankings are South Africa, Kazakhstan, Uzbekistan, Turkmenistan, and Iraq – all countries grappling with deteriorating environmental circumstances in the context of significant economic development pressure and other challenges.
Minister of Water and Environmental Affairs, Edna Molewa, said, in response, ‘the issues of weighting and aggregation are mostly subjective and do not take into account unique national circumstances.’
