Manipal University has once again been ranked at number two overall and first in suburban category among Indian universities in the Universitas Indonesia's Green Metric Ranking for world universities 2012. The results are computed from information provided by universities online. The information relates to six main categories and their weightings are: Green Statistics (15%), Energy and Climate Change (21%), Waste management (18%), Water usage (10%), Transportation (18%), and Education (18%). In the global rankings, Manipal University was placed at 118 among the 215 universities from 49 countries in the overall, 37th in the suburban and 87th in the comprehensive categories respectively. IIT, Madras was the best among the Indian Universities and was ranked 62nd globally. IIT, Bombay was ranked third best in India and 142nd in the world. University of Connecticut was first in the world rankings in the overall and comprehensive categories and the University of Bath topped in the suburban category. Universities from the US, the UK, Japan, and countries in Europe, Palestinian, Chile, Czechoslovakia, Romania and South Africa, China, Fiji, Finland, Greece, Hong Kong, Mexico, and South Africa took part in the survey. The UI Green Metric Ranking is innovative in that it is the first world-wide college-based commitment to the development of sustainable infrastructure, education and research. The ranking methodology is based on a widely accepted principle that measuring sustainability should involve three things: Environment, Economics and Equity (the 3 Es). The ranking not only helps to raise awareness about these issues, but is also proving to be a catalyst to put in place 'green' campus management policies around the world. It is drawing the attention of university leaders and stake holders to combat global climate change, energy and water conservation, waste recycling, and green transportation.
