According to our associate director, "In 2008, NSI [Northern Sydney Institute] reduced its electricity use by 5% on 2007 levels . That’s a saving of 927 tonnes of greenhouse gas emissions. We also purchase 6% of our electricity from renewable energy sources, saving an additional 1,012 tonnes of greenhouse gas emissions. We want to improve on this in 2009."
