Climate action in Canada is accompanied by a host of benefits to communities, including investment, jobs and improved health outcomes. The potential for climate action to advance health is enormous, and has been realized in high profile environmental victories like Ontario’s coal phase out. A transition to net-zero emissions presents an avenue for supporting healthier communities through investments in low-carbon infrastructure. Helping communities identify some of these potential changes in health outcomes, and how to assess these benefits, is critical to ensuring benefits can be identified and advanced through the investment case for low-carbon infrastructure. To address these challenges, these two reports identify some of the health co-benefits, and avoided adverse health outcomes, associated with low-carbon infrastructure investments, and overviews the process for conducting an evaluation of the health benefits associated with reducing air pollution in Canada. The aim of these two reports are to help climate and energy policy decision-makes identify and understand how their investments can drive improvements in health, and how they can evaluate the potential of these changes.
