ANN ARBOR, Mich. — The University of Michigan is reviewing its sustainability goals that were created in 2011, which included five operations-focused sustainability objectives: to reduce greenhouse gas emissions, university transportation emissions and waste tonnage, to purchase sustainable food and to protect the Huron River, reported The Michigan Daily.

A letter co-signed by leaders of 50 student organizations who expressed their continued interest in the 2011 sustainability goals, which many of them helped to create, helped spur the university’s decision.

Despite the 2011 goal to reduce carbon gas emissions by 25%, university data published by the Office of Campus Sustainability show that emissions decreased in 2012, but then increased in 2013. Transportation emissions have seen decreases, but waste production has actually increased since the adoption of the goals. For the full story, click here.
