Pillar 2: Reducing Our Environmental Impact
Pictured Above: Employees touring the greenhouse on campus during orientation.
McMaster University is committed to designing and operating its campus and facilities sustainably and is mindful of the affects its actions have on the environment.
In 2005, McMaster became the first university in Ontario to develop and implement a Sustainable Building Policy. This policy states that every new building on campus will have a minimum of Leadership in Energy and Environmental Design (LEED®) Silver Certification in accordance with the Canada Green Building Council. Reducing water and energy consumption, emissions and waste are just a few ways McMaster can continue to achieve a more sustainable built environment.

Rainwater harvesting is the collection and storage of rain, rather than allowing it to run off. Rooftops are the most viable location for collection to avoid water contamination. Currently, McMaster has a number of rainwater collectors spread across campus. McMaster’s Facility Services Energy Management Plan outlines a proposed project to install new pipelines and pumps to
extract rainwater to be used for irrigation. The project is currently being researched and is estimated to save 648 cubic metres of water annually.

Water System Retrofit in the Life Sciences Building Fish Tank Room
The Life Sciences Building has a fish research room which currently utilizes a significant amount of potable water, approximately 40,000 m3, through fish tanks and drains it to the sewage system, at an annual cost of $140,000 at current water rates. In order to decrease McMaster’s water consumption, a project is in its final stages which involves implementing best practices from fish research labs at the University of Guelph and Environment Canada. The project includes a filtration and circulation system which will reduce water consumption of the fish tanks by approximately 80%, equivalent to 16 Olympic-size swimming pools of water. The project is McMaster’s most significant initiative to reduce water consumption and is expected to be completed in July 2021.

McMaster understands the need for climate action and the important role it can play in addressing climate change through all its sustainability efforts.
Climate change was identified by the McMaster community as a priority area through the President’s Strategy Planning consultations and in the 2020 Shape the Future survey. A key opportunity to address this challenge is through McMaster’s energy and emissions reductions initiatives across campus.

By 2030, McMaster will reduce greenhouse gas emissions on campus by 75%.
This is a reduction of 30,300 tonnes of carbon dioxide equivalent (CO2e) annually,
or the amount of greenhouse gases emitted every year by 9,283 gas-powered cars.
Responsible Investment at McMaster
McMaster is a signatory to the UN Principles for Responsible Investment (PRI).
McMaster University’s invested asset pools each use a responsible investment strategy. Responsible investing integrates environmental, social, and governance (ESG) considerations into investment manager hiring and product monitoring processes. Environmental considerations involve assessing how a company within an invested product have an operational impact on physical natural resources and wildlife and how those impacts are stewarded. Social considerations incorporate how human capital is involved in or impacted by the company’s operations. Finally, governance involves the evaluation of a company’s corporate behaviours, including its complete, relevant, accurate and transparent disclosures to enable effective ESG assessments.Responsible Investment at McMaster: Read More
McMaster’s dedication to reducing its environmental footprint includes the way in which waste is managed.
McMaster aims to develop and promote initiatives which focus on reuse and recycling, composting and reducing single-use plastic. Numerous programs have been implemented on campus, including increasing the number of recycling and composting bins, switching to compostable products in campus eateries, eliminating single-use plastic bags at the Campus Store, and the IT and electronic waste reuse, recycle and disposal initiatives.
For more details on McMaster’s waste management see the
2019 Solid Non-Hazardous Waste Audit.

In 2019: McMaster diverted approximately 52% of materials from landfill,
an 18% increase from the baseline waste diversion rate in 2012.
25% of materials on campus were recycled or reused
26.9% of materials on campus were composted
McMaster Campus Store Eliminates Single-Use Plastic Bags
Previously the Campus Store was selling over 20,000 plastic bags annually. In order to reduce the amount of waste generated at McMaster, the Campus Store collaborated with the Office of Sustainability and developed a plan to remove plastic bags altogether. As of August 2019, there are only donated or reusable bags available at the cash register. The Campus Store plans to work closely with SUSTAIN students and the university to make the store more sustainable going forward. This includes, reusing packing materials when shipping online orders, encouraging buying and selling of used books to reduce emissions from shipping and production and highlighting sustainable products for sale in the Campus Store.
Spotlight: Students pitch signs that make the green choice clear on campus
Students aiming to make environmentally sustainable choices at campus disposal bins sometimes miss the mark, unintentionally placing recyclables in the trash and non-biodegradable products into organic waste bins.
As part of an Advocating for Sustainability course at McMaster University, a group of four students decided to conduct research to learn if signage at the bins impacted disposal behaviour and decided to take a closer look by surveying students on McMaster’s waste sorting.

McMaster recognizes the need for responsible consumption, which includes a reduction in single-use plastics. To meet this challenge, over 200 water fountains and filling stations are available across campus. This allows people to refill reusable water bottles to reduce the use of disposable plastic bottles. Each fountain is equipped with a sensor showing the number of plastic water bottles diverted from landfill.
Takeout containers and packaging contribute to be a large percentage of McMaster’s waste as they travel from restaurant to landfill. In 2019, Hospitality Services implemented compostable cutlery and take-out packaging across campus. The update will replace single-use plastics, annually saving 1.3 million pieces of take-out plastic cutlery and 120,000 plastic straws from landfill. In addition, 194,000 compostable coffee cups were added. Diners can dispose of compostable products in organic food waste bins across campus.
From Trash to Treasure
Created by a team of students enrolled in SUSTAIN 3S03, the aim of the Trash to Treasure project was to reduce IT waste and donate refurbished electronics within the local community. In 2020 the student-run project was the recipient of the Climate Change and Health – Innovation Award through McMaster’s Academic Sustainability Programs Office
Trash to Treasure is now piloting a furniture reuse project where surplus university-owned furniture can be reused directly between McMaster departments and student groups. Before disposing of the furniture, students, staff and faculty are encouraged to post it to the Trash to Treasure Furniture Reuse Group on Facebook. Facility Services is responsible for the pickup and transfer of (university-owned) items posted on the group at no cost.
- 1000 kilograms of IT waste diverted through collection, refurbishment and community donation
- More than 100 computers collected from across campus
- 70 computers sanitized, refurbished and donated to local children in need in collaboration with local non-profit organization greenBYTE
