Earth Hour is a world-wide celebration where millions of people turn off their lights for one hour to tackle the dual challenges facing the planet – climate change and loss of nature. During Earth Hour, TDSB schools and offices are asked to go as electricity-free as possible for ONE HOUR on March 25th at 2pm. Wherever possible, our schools and offices will turn off interior lighting, and any non-essential electronics and power bars.

This year energy reduction will be tracked at each TDSB school, with the top 25 Elementary and Secondary schools getting a shout out. Let’s make this year our biggest energy reduction ever! To help maximize your energy reduction, explore the TDSB EcoSchools Earth Hour resources.

Earth Hour presents a great opportunity to raise awareness about environmental issues and run campaigns focused on energy conservation and climate change. For more information about climate action at the TDSB, check out the Environment, Energy and Climate Action website.
