Tomorrow, Canadians will celebrate Earth Day, the largest environmental event in the world. This year, Earth Day draws attention to its Green Cities campaign, hoping cities will transition to using sustainable, green technologies.

In honour of Earth Day, here are six facts about Canada that you may not know:

• Each year, 6 million Canadians participate in Earth Day.
• Each Canadian emits 14.7 metric tonnes of carbon dioxide on average every year.
• Canada’s average winter temperature in 2013 was 1.6 C above baseline temperature.
• From 1948 to 2013, temperatures in Northern British Columbia and the Yukon increased by 5.4 C.
• Albertans are 25 per cent less likely than others to say that increased flooding is definitely the result of climate change.
• Six in 10 Canadians believe that climate change is real and caused by human activity.
