Toronto's Emissions-based Targets
Toronto's emissions reduction targets are documented in the TransformTO plan (pdf):
- 30 % by 2020
- 80 % by 2050
As of 2017, our remaining emissions-based shares are 99 MtCO2e for a likely chance of remaining below 1.5oC and 463 MtCO2e for below 2oC.
The following charts compares the TransformTO targets with the limits needed to keep below Toronto's emissions-based carbon budgets for < 1.5 or 2oC.
The legends are described below. Click on the charts to see them full size.
The emissions-based emission reduction limits for remaining below 1.5 or 2oC are in this table (below 1990 annual emissions of 27 MtCO2e)
The blue line represents TransformTO's limits and the diamonds represent annual emissions:
20 MtCO2e (6% below 1990 by 2012)
19 MtCO2e (30% below 1990 by 2020)
5 MtCO2e (80% below 1990 by 2050)
The green line represents Toronto's population-based limits for keeping global temperatures from increasing by more than 1.5oC which is the global temperature increase that Canada pledged to pursue in the Paris Agreement ("pursuing efforts to limit the temperature increase to 1.5 °C above pre-industrial levels")
The yellow line represents the limits for keeping global temperatures remaining below 2oC. This is the maximum global temperature increase that Canada pledged in the Paris Agreement ("holding the increase in the global average temperature to well below 2 °C above pre-industrial levels")
The red line represents the limits for preventing temperatures from rising above 3oC. This global temperature increase would lead to climate chaos, and we pledged to do our share to prevent this.
