"The rating was based on the UI Green Metric Ranking of World Universities initiated in July 2012 by UI," the university`s deputy rector for academic and student Affairs, Muhammad Anis, said at the UI hall in Jakarta`s southern outskirts of Depok on Tuesday.
Meanwhile, University of Connecticut in the US is rated as the world`s greenest campus, followed by University of Nottingham in the UK, and University College Cork National University of Ireland.
Besides UI, Anis said the other university in Indonesia that belongs to top 30 most green campuses is the Bogor Institute of Agriculture (IPB), in 27th position.
"The UI Green Metric Ranking of World Universities 2012 was taken part by 215 universities from 49 countries, including China, the UK and the US," he said.
"The number of universities taking part in last year`s event was larger than that in the first event held in 2011, with 178 universities," added Anis.
The online "green" ranking for world universities was spearheaded by UI in 2011 and officially accepted as a member of International Ranking Expert Group (IREG) Observatory in the 6th IREG Conference held in Taipei, Taiwan, in April 2012.
The 2012 event was the second year of this ranking system which allows universities in both developed and developing countries to compare their efforts in developing environmentally friendly campuses.(*)
