Canada's share of the carbon budget

The limit on the amount of CO2 that the atmosphere can safely contain is known as the carbon budget. There are different limits depending upon the maximum global temperature increase that is acceptable and the likelihood of this happening. In addition, the limit is determined by Canada's share of the global carbon budget.

A comparison of the possible targets

This table compares our current targets with what they need to be if we want to remain under our population share of the carbon budgets for contributing to our pledge to keep temperature increases below 2 degrees.

Current targets
Necessary reductions for keeping temperature increases below 2 degrees
2020   49%
2025   100%
2030 30%  
2050 80%
