The October 2018 IPCC Special Report (SR15) increased the Global Carbon Budget for a 66% 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 per-capita sharing. (We are working on updating this.)

Emissions sharing

The global carbon budget could be shared as a country's share of global emissions (also referred to as Inertia).

Canada's share of global emissions is approximately 1.7%. The chart represents these limits and the cumulative emissions if Canada were to attempt to stay within those limits compared to the cumulative emissions if Canada follows the Pan-Canadian targets of 30% of the 2005 levels (747 MtCO2e) by 2030 and 80% by 2050.
