The publication rates a college by its sustainability-related policies, practices and programs. It then adds up the scores to find the ranking. The UI was one of just 22 schools with a perfect score of 99.
It's for investing money into buildings, making sure they use less energy and opening up some LEED platinum ones, like the new Business Instruction Facility and Lincoln Hall.
UI is also working on becoming carbon-neutral by 2050. It means emitting no carbon dioxide from campus. To get CO2 levels down to zero, it will take a lot of education and initiatives. It's something the new Institute for Sustainability, Energy and Environment is ready to take on. It was just created in December.
UI has been in the Princeton Review Guide to Green Colleges for the past five years. Only colleges with a score of 83 or above make it.
