This document captures the findings from the breakout group sessions from the Dan Leckie Forum 2015 “Transformation Toronto 2050 – Mapping the Pathway to an 80% Reduction.” The group sessions asked about community stakeholders, knowledge sharing, community mobilization and participation, and long-range carbon emission modelling exercises. They also considered the impact of low-carbon scenarios on factors such as public health mobility, prosperity, and social justice. The results paved the way for the TransformTO initiative.
