  • Toronto’s emissions rose by 1.3% in 2021. To achieve the City’s net zero targets by 2040, pace of reductions needs to increase significantly.
  • Building emissions are the largest source at 61%. Total number of dwelling units is projected to increase by one third if all currently planned and active construction is completed.
  • Transportation emissions have increased slightly (3.3%) but have not fully rebounded to pre-pandemic levels. Cycling activity continues to increase, reaching its highest levels since data became available in 2018.

Innovation in Toronto

Toronto is the first municipality in the region to update its parking by-laws to remove mandatory parking minimums in multi-family buildings and require 100% of new parking to be EV ready. This innovative approach was informed by a TAF sponsored report from the Clean Air Partnership exploring the best way to prepare for the coming EV revolution for home charging.
