A new study has concluded that sustainable aviation fuel (SAF — jet fuel made from wastes, residues or synthetic sources rather than crude oil) holds substantial economic potential for Canada, adding weight to calls for a domestic production and policy framework.

The study, reported by International Airport Review, frames SAF not only as a decarbonisation tool but as an industrial opportunity: feedstock supply, refining capacity and export potential all sit inside Canada's existing agriculture, forestry and energy sectors. That framing matters for airlines, because SAF availability — not aircraft technology — is now the binding constraint on most carrier net-zero commitments.

Why a study about fuel economics matters to airlines

What does this change for Canadian aviation? In the near term, nothing on its own. A study is not a mandate, a refinery or a purchase agreement. Its function is political and commercial: it gives regulators, provinces and potential producers an evidence base to justify investment in a sector where demand is guaranteed by targets but supply is not.

Canada's carriers, like their counterparts in the United States and Europe, face mandates and voluntary commitments that scale up over the coming decade. Fuel is the largest single line in an airline cost structure after labour, typically around a quarter of operating costs. Any domestic SAF supply chain that scales would shift part of that exposure from imported fuel to domestic production — with the price premium, and the jobs, staying in Canada.

The mechanism the study rests on

SAF economics turn on three variables: feedstock cost and availability, capital cost of conversion plants, and the policy credits that close the price gap with conventional jet fuel. Canada is unusually well positioned on the first — agricultural residues, forestry by-products and waste streams are abundant and, unlike in more densely populated markets, largely untapped.

The study's economic-potential case therefore rests on a simple mechanism: convert low-value domestic residues into high-value drop-in fuel (fuel certified to blend directly with conventional jet fuel, requiring no engine or infrastructure changes), and capture the margin that foreign producers currently take.

What is proven versus what is promised

A note of discipline is warranted. Studies of economic potential describe what a sector could deliver under favourable policy and investment conditions; they are not delivery records. Canada today produces SAF at minimal volumes, and no large-scale commercial plant of the type envisioned is operating. The gap between the study's potential and actual litres delivered will be closed — or not — by capital commitments, feedstock logistics and federal policy instruments such as mandates or credits, none of which the headline alone resolves.

For network planners and fleet strategists, the practical signal is medium-term: watch for plant final investment decisions and federal SAF policy, not announcements. Those two indicators, more than further studies, will determine whether Canada becomes a producer or remains a buyer.
