National Sweater Day

Join us February 3, 2022 and wear a sweater in support of climate action


National Sweater Day

*In light of the rapidly evolving coronavirus outbreak, please practice social distancing and follow government guidelines for gatherings and activities. The health and safety of educators and students are our top priorities.*

Since 2010, more than a million Canadians have shown their support for limiting global temperature rise to 1.5 degrees Celsius by turning down their thermostats by the same amount (or more) and wearing their favourite sweaters to stay warm.

National Sweater Day is an opportunity to raise awareness about climate change and energy conservation, and show how together – classroom by classroom, school by school – we can be a part of the solution. Make an impact beyond National Sweater Day by asking students to reflect on their personal carbon footprint and make personal commitments in their own lives to help keep climate change in check. Collectively, we can have a powerful impact.
