The October 2018 Intergovernmental Panel on Climate Change (IPCC) Special Report increased the Global Carbon Budget for a likely (66%) probability of keeping global temperature increases below the dangerous 1.5 degrees. As a result, we have modified and simplified our charts. The revised carbon budget is 420,000 Mt CO2. Many calculations and charts are still based on the 2014 IPCC report and are biased towards population sharing. (We are working on updating this.)

Canadian Provinces' Share of the Carbon Budget

In 2016, Canada's share of the global carbon budget can be calculated based on various sharing strategies.

 

We have created charts of the years that Canadian provinces have left until they have used up their share of the global carbon budget. These charts are based on 2016 data and assume that we continue emitting at the same rate. Reducing the rate will increase the time remaining.

 

We removed the Newfoundland and Labrador (NL), Prince Edward Island, Yukon and Manitoba from the chart above because due to their fraction of global emissions being so low (see the data below) they had over 60 years remaining.

 

The numbers in this table are based on 2016 data (population and emissions).
