Canada's Fair Share of the Global Mitigation Effort

This is a discussion of Canada's fair share of the carbon budgets as defined by the Civil Society Review of INDCs.

The important point to take away from this discussion is that Canada will not be able to contribute our fair share of the global mitigation effort without very substantial international mitigation support.

Canada's fair share of the global mitigation effort if we follow the Climate Equity Share mechanism

The charts below were obtained from the Canadian supplement to this report (pdf)

Below 1.5 degrees C

The following chart illustrates what Canada's fair share would be if Canada were to do our fair share of keeping temperatures from rising above 1.5C. It suggests that Canada's fair share emissions reduction should be as large as all of our domestic emissions around 2027 and approximately 125% of our domestic emissions by 2030.

 Emissions consistent with Canada’s pledged emission reductions

 Mitigation funded by Canada and carried out within its own borders.

 Mitigation funded by Canada and carried out within other countries

Canada's "Fair" Carbon Budgets

This chart compares different methods of sharing Canada's carbon budgets.
