In 2016, the City began a technical modelling exercise to assess how greenhouse gas emissions will change over time in key sectors – buildings, transportation, waste, energy sources, land use – given current federal, provincial and municipal policies and programs.

TransformTO technical modelling was used to measure and identify the potential impact of various combinations of emission reduction strategies and actions, with the goal of identifying the best and most effective strategies to reduce our greenhouse gas emissions.

The strategies and actions that were modelled were identified through two main sources – input provided by the community through an online TransformTO survey done in 2016 and community conversation events, and a formal review of best practices of strategies being implemented in cities around the world.

In 2020, the City undertook another round of technical modelling to assess how greenhouse gas emissions will change over time in key sectors – buildings, transportation, waste, energy sources, land use – given current federal, provincial and municipal policies and programs.

TransformTO Net Zero technical modelling was used to measure and identify the potential impact of various combinations of emission reduction strategies and actions, with the goal of identifying the best and most effective strategies to reduce our greenhouse gas emissions to net zero.

The strategies and actions that were modelled were identified through three main sources – actions included in the existing TransformTO strategy, input provided by the community through ongoing public and stakeholder consultations, and best practices from strategies being implemented in cities around the world.

The TransformTO Net Zero Strategy Technical Report provides an overview of the technical modelling process, assumptions and methods.
