Why Airports Need Benchmarking?
Ask an airport CEO how their operation performs, and you’ll get a confident answer: passenger volumes are up, emissions targets are on track, the sustainability report looks good. Ask how that compares to the airport down the runway, or the one three provinces over, and the confidence usually thins out. Most airports can tell you a great deal about themselves. Far fewer can tell you where they stand next to their competitors.
That gap is becoming harder to justify. Airports today face the same pressures that reshaped oil and gas a generation ago: mounting regulatory disclosure requirements, investors not only asking for, but requiring disclosure about emissions and governance, and a public that increasingly aware of and fatigued by greenwashing and green hushing.
The Oil and Gas Precedent
Operational benchmarking wasn’t always standard practice in oil and gas. Twenty years ago, most operators reported their own numbers, on their own terms, and left it at that. That changed as investors began demanding comparable, third-party-validated data on cost per barrel, safety incidents, emissions intensity, and environmental risk. Today, an operator that can’t say where it ranks against peers on carbon intensity is at a disadvantage in capital markets. The absence of a benchmark reads as a warning sign to investors, talent, consumers, and activist groups.
Airports are arriving at a similar inflection point. Emissions disclosure requirements are tightening, particularly in Canada. Investors and government funders want hard numbers to see quantitative comparative analysis to evaluate risk. Sustainability claims with no peer context are also more vulnerable to Bill C-59 exposure: Canada’s strict greenwashing ban, with extremely high penalties for violators.
The Objection to Consider
The most common pushback revolves around airports being too different to compare fairly, a justifiable question worth exploring. A regional airport moving a few hundred thousand passengers a year has little in common with a hub processing tens of millions. Climate, geography, terminal age, and traffic mix all vary enormously. Ranking them side by side on raw numbers is misleading. Hence, a formula for quantifying such aspects as quantitative KPIs, comparative analysis, qualititative governance, and internal policy impact, is needed.
That objection is correct about raw numbers and wrong about benchmarking itself. Credible benchmarking normalizes absolute figures, rather than simply normalizing them. GHG emissions per passenger, water use per performance unit, waste generated relative to cargo volume: these are the metrics that let a small regional airport and a major hub be compared on equal footing, without one being penalized simply for being bigger. The “we’re too different” argument is an argument for better methodology, not an argument against benchmarking at all. Oil and gas operators made the same case in the early days of ESG reporting, and the industry solved it with normalized, activity-adjusted metrics rather than by opting out of comparison altogether.
What Benchmarking Gives Airport Leadership
For a CEO or executive team, a rigorous, independent benchmark delivers several things that internal metrics alone cannot.
It tells Airports where they stand. An internal year-over-year improvement can look good on paper while still trailing every comparable airport in the country. Without a peer set, there’s no way to know which is true.
It sharpens competitive position. Airports compete for airline routes, cargo contracts, and government infrastructure funding. Increasingly, ESG and operational performance are part of that pitch, and a credible external ranking carries more weight than a self-authored sustainability report.
It turns ESG goals into tangible targets. “Improve our environmental performance” is not a KPI. “Reduce GHG emissions per passenger by X to close the gap with the top quartile of Canadian airports” is. Benchmarking gives operations teams a specific, external reference point to work against, rather than a target the airport invented for itself.
It gives employees a baseline. Staff working toward an internally generated number often can’t tell if that number represents genuine progress or a low bar. A peer benchmark has the power to guesswork with a defensible standard.
It strengthens the story told to investors and the public. Touting sustainability performance is mainly marketing. However, proving it against a documented, independent standard is what builds trust with investors, regulators, and communities. This provides protection against Bill C-59, and it’s a stronger marketing position than any internally written report can be.
The Standard Is Coming Either Way
Oil and gas operators adopted benchmarking because the market stopped accepting unverified claims, and the operators who resisted longest paid for it in access to capital and reputation. Airports are heading toward the same reckoning, just a few years behind.
The airports that get ahead of comparative benchmarking will be the ones that can prove, against a documented and independent standard, exactly where they stand compared to their peers. The ones set apart will be the ones who can use this information to execute meaningful programs to improve their standing and metrics, ground their marketing around that execution in fact and in accordance with Bill C-59, and use Benchmarking as a tool for a competitive advantage.
