the toronto climate week challenge!
Move from inspiration to action! The Toronto Climate Week Challenge launches October 1, focusing on one of the biggest ways that we as individuals can have an immediate and lasting impact… choosing what we eat. Challenge participants will commit to cooking one of a list of delicious, climate-smart meals that has an intentionally lower carbon footprint. They’ll also be healthy and affordable! You’ll be rewarded with incredible deals from some sustainable food brands, and by a real-time tracker of how much CO2e you reduced through the challenge.
