On Thursday, February 17, 2011, WWF is calling on all Canadians to turn down their thermostats 3° and wear a fun, wacky sweater to symbolize their commitment to the environment.
You can participate at home, in your community or in your workplace. WWF-Canada has even created participation toolkits to guide the development of your own National Sweater Day party
