Getting to net zero requires major changes in the large-scale systems we use to meet societal needs, including the way we produce and distribute energy, move people and goods, produce and consume food, and build and live within our cities. This report is intended as a decision-support tool and reference document for those tasked with figuring out how to do this. It provides an assessment of different pathways to net zero for eight critical sectors and systems in Canada. The Transition Accelerator will be adding to this work over time, and will update the report periodically.
