Since 1999, University Health Network’s (UHN) Energy & Environment department, has steered environmental stewardship at UHN, bringing a sustainability lens to the hospital’s vision of “A Healthier World”.
Embodying the value of stewardship, the team supports UHN’s purpose of “Transforming lives and communities through excellence in care, discovery and learning” by collaborating across the organization to create a culture of sustainability. UHN leads healthcare environmental sustainability locally, nationally, and around the globe. In 2019, UHN was recognized with Global Green & Healthy Hospitals 2020 Health Care Climate Challenge gold awards for Climate Resiliency and Climate Leadership, and Smart Commute’s platinum designation for sustainable transportation.
By embedding a systematic approach to environmental stewardship, UHN receives a triple benefit to environmental, financial, and human health that far outweighs the efforts. This core UHN value powers patient and planet-centred care.

Profiles presented are based on information provided by participants. Participants’ GHG emissions performance published are based on utility data submitted and converted to GHG emissions. The emission factors applied aligns with the period of energy data reported (2019). The emission factors utilized for the conversion are calculated based on a combination of sources: Government of Canada (National Inventory Report & Canada’s Proposed Greenhouse Gas Quantification Requirements), Government of Ontario (Guide: Greenhouse Gas Emissions Reporting), The Atmospheric Fund (A Clearer View on Ontario’s Emissions – Electricity emissions factors and guidelines) and Enbridge Gas Inc. (Chemical Composition of Natural Gas).
