The Global Coalition for Green Schools, part of the USGBC's Center for Green Schools, awarded Dunbarton High School in Ontario, Canada, the 2015 Greenest School on Earth award.

The Global Coalition for Green Schools, an initiative of the Center for Green Schools at USGBC, announced the 2015 Greenest School on Earth. The recipient school is Dunbarton High School of Pickering, Ontario, Canada.

The Greenest School on Earth is an annual competition, highlighting a K-12 school that exemplifies how sustainability can be integrally woven into the infrastructure, culture and curriculum of a school. The Center defines a green school as one that achieves zero environmental impact (including energy, water, waste and carbon), a positive impact on occupant health and performance, and 100 percent environmentally literate graduates. These traits are encompassed in three pillars – environmental impact, human health and ecoliteracy. The Greenest School on Earth designation includes a $1,000 award to be used by the selected school for a sustainability initiative.

"The Greenest School on Earth recognition goes to the school that is defining what it means to live, breathe and teach whole-school sustainability," said Rachel Gutter, director of the Center for Green Schools. "Dunbarton High School is an excellent example of a school that engages its students at every turn, placing them in the driver's seat and empowering them to improve their environment, inside and out. We are pleased to recognize Dunbarton's efforts to improve their community, enhance the biodiversity of the region and elevate young minds to a higher order of thinking about sustainable practices."
