When it comes to going green, some universities are taking on the world.
In its annual report, UI GreenMetric, a worldwide university ranking system, listed 215 of the world's most sustainable and eco-friendly campuses of 2012. Schools were ranked on areas of setting and infrastructure, energy and climate change, waste, water, transportation and education.
Although most of the top spots belonged to universities in the United States and United Kingdom, there were also schools from Ireland, Sweden and Malaysia. Top schools had extensive programs in reducing their carbon footprint, campus-wide initiatives to eat (and grow) organic food and campaigns geared toward decreasing dependence on electricity.
