The University of Toronto has been ranked the most sustainable university in the world for the second consecutive year.
The 2025 edition of the QS World University Rankings: Sustainability, released this week (Dec 9) by London-based Quacquarelli Symonds, placed U of T first overall out of more than 1,700 institutions across 95 countries.
The closely watched ranking evaluates post-secondary institutions for their environmental impact, social impact and governance.
"On behalf of the University of Toronto, I am thrilled that our university is once again ranked first in the world in the QS Sustainability Rankings," said U of T President Meric Gertler. "The U of T community is profoundly committed to the advancement of sustainability as one of the most urgent challenges of our time.
"This year's ranking confirms our resolve to help lead the way to a sustainable future."
First launched in 2022, the ranking assesses universities based on QS World University Rankings data, including reputation surveys and research output related to the 17 UN Sustainable Development Goals. It also looks at institutional policies, operational data, alumni impact and national data from the Organisation for Economic Co-operation and Development (OECD) and World Bank.
To determine environmental impact, the ranking evaluates environmental education, research and sustainability. For social impact, it examines employability and outcomes, equality, health and well-being, impact of education and knowledge exchange. And for governance, the ranking looks at indicators such as student representation and transparent financial reporting.
U of T performed particularly well in the social impact category this year, moving up three spots to first globally. It also ranked fifth in the world for environmental impact and tied for 23rd in governance.
U of T's performance led a robust showing by Canadian universities. The University of British Columbia shared fifth spot with University College London, making Canada the only country to have two universities in the top five. Two other Canadian universities placed in the top 50: McGill University (15th) and Western University (30th).
The QS sustainability ranking comes as U of T forges ahead with a host of climate-focused initiatives on its own campuses including: Project Leap, a $138-million infrastructure project that will cut emissions on the St. George campus in half by 2027; Project SHIFT, a U of T Mississauga initiative to speed up the transition from natural gas to electricity; and a combination of new climate-responsible constructions and energy retrofits to older buildings at U of T Scarborough.
Spurred by these and other efforts, the university's three campuses last year made a landmark commitment to reduce more greenhouse gases than they emit in the coming years. And U of T continues to make progress on its pledge to divest from fossil fuel investments in its endowment fund.
At the same time, U of T is working to enhance Canada's green energy sector through projects like the Grid Modernization Centre, a state-of-the-art facility led by Climate Positive Energy, an institutional strategic initiative, that will serve as a hub for testing, development and commercialization.
U of T is also playing a leadership role in sustainability by engaging with regional, national and international partners. For example, the university acted as a founding member of the City of Toronto's Green Will Initiative, collaborated with the Urban Climate Action Project to help implement the city's TransformTO climate action strategy and contributed to the Toronto Region Board of Trade's Banking on Green playbook, which helps Ontario organizations fund green retrofit projects.
Globally, U of T has convened networks aimed at mobilizing multi-sector partnerships, including the U7+ Alliance of World Universities, the University Climate Change Coalition (UC3) and the International Sustainable Campus Network (ISCN). U of T's sustainability leaders have also been asked to share knowledge and experiences with other universities in Canada, the U.S., Mexico, Germany and other countries.
Most important, U of T is actively creating a new generation of sustainability leaders. Supported by the President's Advisory Committee on the Environment, Climate Change, and Sustainability (CECCS), which recently created a new student leadership subcommittee, more than 2,000 undergraduate courses in 2024-25 now have a sustainability orientation.
Students also have the option of exploring sustainability from various lenses through the Sustainability Pathways program, or to contribute to projects on- and off-campus via the Campus as a Living Lab and Community-Engaged Learning programs.
Overall, U of T continues to be the highest-ranked Canadian university and one of the top-ranked public universities in the five most closely watched international rankings: Times Higher Education's World University Rankings, QS World University Rankings, ShanghaiRanking Consultancy's Academic Ranking of World Universities, U.S. News & World Report's Best Global Universities and National Taiwan University World University Rankings.
