Toronto School District Energy Efficiency

Toronto, Ontario


Energy Efficiency

Technical details

Starting in 2000, the Toronto District School Board began updating lighting fixtures and the control systems that handle heating, lighting, and ventilation. The replacement units consume less electricity, and the efficiency of the new control systems reduces the amount of fossil fuel used for heating. The board further reduced energy consumption by improving school roofs so they’re much better at insulating. This is Canada’s largest school district, encompassing 583 schools, so the overall energy savings are substantial.

They’re also expensive, so the district has done the project gradually, retrofitting a few dozen buildings each year. To help cover the costs, the district has sold carbon offsets (also known as carbon credits). The offsets represent emissions avoided by reducing the use of fossil fuel for heating and electricity generation. During 2015, the district created 17,600 offsets, representing 17,600 metric tons (19,401 US tons) of carbon dioxide or equivalent greenhouse gases kept out of the atmosphere. Cloverly has purchased 430 of those offsets.

Cloverly buys offsets that meet accepted standards for being real, measurable, verifiable, permanent, and additional. "Additional" means that the carbon savings would not have happened without the offset project and that the project would not have happened unless it got certified to sell carbon offsets. CSA oversees verification of the Toronto District School Board project. You can find verification documents at
