The largest portion of carbon emissions at many Canadian institutions comes from your purchases rather than your boilers or energy. For instance, Université de Montréal's acquisition of goods and services was the single largest component of its Scope 3 emissions profile in 2022–2023, accounting for almost 21,000 tons of CO2 equivalent. Research indicates that 70–90% of the nation's higher education institutions' overall emissions are concealed in Scope 3, with a large portion of these emissions found in food, paper, furniture, lab supplies, and IT equipment.
At The Green Campus Collective (TGCC), we assist mission-driven organizations, institutions, and student groups in transitioning from "climate-positive" catchphrases to actual, quantifiable reductions. And the first step in doing so is to view campus procurement as a fundamental climate lever rather than merely a financial issue.
What are Scope 3 emissions (and why do they matter)?
To put it simply, scope 3 emissions are all the indirect emissions associated with your company that you have no direct control over, such as the waste that ends up in landfills, the factories that build your laptops, the vehicles that distribute your textbooks, and the raw materials suppliers.
For Canadian universities, this category often includes:
- Purchased products and services (uniforms, furniture, lab equipment, office supplies)
- Capital projects and construction (new structures, renovations)
- Business travel, upstream energy use, and commuting for employees and students
According to recent Canadian research, less than half of colleges regularly compute their entire Scope 3 footprint, and many still only report Scope 1 (direct) and Scope 2 (bought energy). Because of this disparity, campuses may appear to be "clean" on paper but actually contribute significantly to emissions that are not reflected in their reports.
Why campus procurement is a climate hotspot
One of the most significant levers in education is procurement. Every time your campus purchases a new software-as-a-service contract, a box of printer paper, or a field trip bus, you are voting with your budget for specific supply chains, along with the waste streams, labour standards, and emissions that go along with them.
Key points for Canadian campuses:
- A study of Canadian‑based universities found that only about half currently calculate total procurement‑related Scope 3 emissions, and many still rely mainly on certifications (like “green” labels) rather than actual emissions data.
- At the University of Calgary, early Scope 3 analysis showed that fuel and energy‑related activities, construction, and purchased goods can easily dwarf on‑site emissions, even where the campus itself runs on low‑carbon electricity.
- Scope 1 and 2 may appear minor due to Canada's relatively clean grid in many areas, but Scope 3 can still be enormous, particularly when campuses import specialized equipment, furnishings, or food from high-carbon locations.
In short: if your campus is serious about climate goals, you can’t keep treating procurement as a black box.
How to start supplier engagement (without being “that university”)
It is not necessary to begin supplier interaction with a 50-page sustainability questionnaire. At TGCC, we assist campuses in starting with high-impact, low-friction measures that are realistic for both you and your vendors.
Here’s a practical starter kit:
-
Map your emissions hotspots
- Use spent data and tools like environmentally extended input‑output analysis (EEIOA) to flag the biggest contributors: IT, cleaning, catering, print‑and‑copy, lab supplies, uniforms, and construction.
- Focus on top‑20% of suppliers by spend, since they usually drive 70–80% of procurement emissions.
-
Frame engagement as partnership, not policing
- As Environment and Climate Change Canada and other guides stress, suppliers respond better when they’re treated as partners with shared goals, not data‑collection targets.
- Offer feedback loops, simple digital tools, and recognition (e.g., a “Green Supplier” badge or priority in rebidding) instead of pure compliance checks.
-
Start small, then scale
- Pilot with one or two high‑impact categories (for example, catering and printing) and build templates that can be reused across contracts.
- Use existing Canadian‑sector work, like York University’s case study on Scope 3 procurement, to avoid reinventing the wheel.
Simple questions to ask vendors (Canada‑context version)
You don’t need to become a carbon auditor overnight. A few sharp questions can quickly reveal whether a supplier is at least thinking about emissions. Here are examples TGCC uses with Canadian campuses:
For IT and electronics vendors:
- What percentage of your products are Energy Star certified or EPEAT‑registered, and how do you track embodied carbon?
- Do you offer take‑back or leasing models for laptops and desktops, and how do you manage end‑of‑life recycling in Canada?
For food and catering services:
- What share of your food is Canadian‑grown or locally sourced? How do you track food‑related emissions (transport, packaging, food waste)?
- How are plant‑forward menus and waste‑reduction initiatives built into your contracts?
For cleaning, print, and office supplies:
- What proportion of your paper and packaging is recycled or FSC‑certified?
- Do you track and report Scope 3 emissions for key products, and can you share a simple carbon‑per‑unit estimate (e.g., CO₂ per ream of paper)?
For construction and furniture suppliers:
- Can you provide environmental product declarations (EPDs) or lifecycle data for major materials (steel, concrete, flooring, furniture)?
- Do you prioritize low‑carbon or recycled materials and on‑site waste reduction on education projects?
Asking these questions shifts the culture from “We’re just buying stuff” to “We’re choosing supply chains.”
A Canadian example: How one campus changed one major contract
A recent Canadian case study on York University shows how even incremental changes in procurement can start to move the needle.
Key moves:
- The university started incorporating sustainable procurement standards into significant contracts, particularly for IT equipment, culinary services, and cleaning.
- Using the same kind of inquiries mentioned above, procurement staff began requesting basic emissions-related statistics and reduction plans from vendors rather than depending solely on "green" labelling.
- The institution developed a repeatable procedure that didn't deplete staff bandwidth by concentrating on high-spend categories and utilizing a standardized vendor questionnaire.
The result? York has not only improved transparency around its Scope 3 footprint but also shifted market signals—showing vendors that Canadian higher‑ed institutions are willing to pay for lower‑carbon options, not just the cheapest bid.
Your next move: Turn procurement into a climate strategy
Campus climate plans frequently end with "buy more LED bulbs" and "turn off the lights." However, eliminating the pickle while disregarding the rest of the burger is akin to dieting if your Scope 3 emissions account for 70–90% of your footprint.
TGCC assists campuses throughout Canada:
- Determine and share the Scope 3 emissions associated with their procurement.
- Create lean supplier engagement templates that comply with Canadian procurement regulations and Privacy-by-Design.
- Create a straightforward, consistent method for rating vendors based on social and environmental performance rather than just pricing.
TGCC can assist you in creating a 12- to 24-month supply-chain strategy that suits your campus, budget, and culture if you're prepared to view procurement as a key climate lever rather than an afterthought.
