The most recent estimate of Canada's greenhouse gas emissions in 2010 is 809 million tonnes  - expressed as their carbon dioxide equivalent. This is based on "business as usual" or "do nothing to curtail them".

Transportation, electricity, industry and buildings are major sources of carbon dioxide.

Oil and gas production contributes both carbon dioxide and methane.

Agriculture contributes mostly methane and nitrous oxide.

Our rotting landfills contribute methane equivalent to 27 million tonnes of carbon dioxide.
