If Toronto follows City Council's TransformTO, we will not reach zero GHG emissions until after 2050. Our fair share of the limit on cumulative emissions to keep global temperatures from rising above 2 degrees requires us to reach net-zero emissions before 2040. However, in the Paris Agreement, Canada pledged to aim to keep global temperature increases well below 2 degrees C and to aim to keep them below 1.5 degrees C. To achieve this Toronto's goal should be to reach net-zero (carbon neutral) by 2025.
