The UMass Amherst campus is known for its sustainability. In 2010 the UMass Climate Action Plan (CAP) was approved, which documented the campus' plan to reach carbon neutrality by 2050. In 2011 UMass Amherst became one of the four colleges to receive a gold star from the Association for the Advancement of Sustainability in Higher Education. In 2013 UMass Amherst made it onto the Princeton review's Green Honor Roll and in 2014 received its second National Climate Leadership Award. Furthermore, this is one of the only public universities to use the fresh fruits and vegetables in the dining commons from its very own permaculture gardens.
