On October 2, 2019 Council voted unanimously to declare a climate emergency and accelerate efforts to mitigate and adapt to climate change.

TransformTO is Toronto’s ambitious climate action strategy. Unanimously approved by City Council in July 2017, TransformTO lays out a set of long-term, low-carbon goals and strategies to reduce local greenhouse gas emissions and improve our health, grow our economy, and improve social equity.

On October 2, 2019 City Council voted unanimously to declare a climate emergency and accelerate efforts to mitigate and adapt to climate change, adopting a stronger emissions reduction target of net zero by 2050 or sooner. In the summer and fall of 2019, residents of Toronto, including the TransformTO Reference Panel, were invited to provide input into the next TransformTO Implementation plan. Due to the COVID-19 pandemic, the development of both the plan and public consultation report were delayed. The 2019 consultation report is now available.

Feedback from the 2019 TransformTO public consultation was reviewed in the preparation of the Toronto Office of Recovery & Rebuild Report and will also inform the design of the TransformTO Net Zero strategy currently under development.

Toronto’s greenhouse gas (GHG) emissions reduction targets, based on 1990 levels:

  • 30 per cent by 2020
  • 65 per cent by 2030
  • Net zero by 2050, or sooner

Achieving these targets will require transformational changes in how we live, work, build and commute.
