Lyon Saint-Exupéry Airport: France’s First Major Hub to Hit Net-Zero Emissions—But Why Does It Still Lag Behind Marseille in Passenger Traffic?
Lyon Saint-Exupéry Airport, France’s fifth-busiest airport by passenger volume, has achieved a historic milestone: it became the first major French airport—handling over 10 million travelers annually—to reach net-zero carbon emissions as of May 2025. Yet despite this environmental leadership, the airport remains firmly in fifth place nationally, trailing Marseille, Nice, and the two Parisian hubs. How did Lyon become a sustainability pioneer while still playing catch-up in passenger numbers? And what does this mean for France’s aviation future?
The answers lie in a combination of aggressive decarbonization efforts, a post-pandemic recovery still in progress, and the persistent dominance of low-cost carriers—a model that has reshaped Lyon’s role in France’s aviation landscape. With 10.46 million passengers in 2024 (verified), Lyon has clawed back 4.7% growth year-over-year but remains 10.9% below its 2019 pre-COVID peak of 11.9 million. Meanwhile, Marseille’s 2024 traffic of 11.2 million (Union des Aéroports Français data) has allowed it to overtake Lyon in rankings—a shift that reflects broader regional dynamics.

Net-Zero First: How Lyon Saint-Exupéry Slashed Emissions by 94%
Lyon’s net-zero achievement is not just symbolic—it’s the result of a decade-long environmental action plan overseen by VINCI Airports, the operator since 2016. Between 2013 and 2024, the airport reduced its direct CO₂ emissions (Scopes 1 and 2) by 94%, a feat recognized with the international ACA 5 certification—the highest standard for airport sustainability. The milestone was reached one year ahead of schedule, with residual emissions offset through local reforestation projects in the Beaujolais region, certified under the Low Carbon Label.
The decarbonization strategy targeted four key areas:
- Electricity: 100% solar-powered self-consumption, LED lighting upgrades, and green electricity guarantees (origin-certified renewable sources).
- Heating: Full transition to biogas (with origin guarantees) and heat recovery from co-generation (biogas-powered electricity production).
- Fuels: Fleet electrification and optimization of ground-service vehicles.
- Air Conditioning: Replacement of outdated equipment and leak-prevention protocols for refrigerant fluids.
VINCI Airports’ CEO, Jean-Charles Decaux, emphasized in a February 2025 statement that the achievement was “not just about reducing our own footprint, but setting a new standard for Scope 3 emissions—helping airlines, handlers, and tenants decarbonize their operations.” The airport now commits to maintaining emissions below 500 tonnes of CO₂ equivalent annually, a threshold far stricter than France’s national aviation targets.
“Lyon Saint-Exupéry is proving that sustainability and growth can go hand in hand. Our 2024 traffic growth of 4.7% shows demand is there—we just need to ensure our infrastructure keeps pace.”
Why Is Lyon Still Fifth? The Low-Cost Paradox
While Lyon leads in sustainability, its passenger traffic remains constrained by two structural factors: its reliance on low-cost carriers (LCCs) and geographic competition.
In 2024, 52% of Lyon’s traffic was low-cost (verified), a share that has grown steadily since VINCI’s acquisition. This model drives affordability but limits Lyon’s appeal for premium travelers compared to Paris or Nice. Meanwhile, Marseille’s proximity to major Mediterranean routes and its role as a gateway to North Africa and the Middle East have helped it surpass Lyon in rankings.
Key Traffic Comparisons (2024):
| Rank | Airport | Passengers (2024) | % vs. 2019 Peak | Low-Cost Share |
|---|---|---|---|---|
| 1 | Paris Charles de Gaulle | 76.2 million | 92% | 38% |
| 2 | Paris Orly | 47.8 million | 95% | 45% |
| 3 | Nice Côte d’Azur | 13.1 million | 98% | 22% |
| 4 | Marseille Provence | 11.2 million | 102% | 30% |
| 5 | Lyon Saint-Exupéry | 10.46 million | 88% | 52% |

What’s Next for Lyon? Summer 2025 and Beyond
Lyon’s operators are betting on two levers to accelerate recovery: expanded long-haul routes and sustainability as a competitive edge. The airport now offers 120+ direct destinations (verified), including new connections to Dubai, Istanbul, and Bangkok in 2025. Yet the challenge remains: Marseille’s 2024 traffic growth of 6.1% (Marseille Airport data) outpaced Lyon’s, partly due to its stronger leisure-travel positioning.
Looking ahead, Lyon’s net-zero status could become a marketing differentiator. VINCI Airports has already partnered with Air France-KLM and EasyJet to co-fund a hydrogen-powered ground vehicle pilot program, set to launch in 2026. If successful, the initiative could attract environmentally conscious travelers willing to pay a premium.
Next Checkpoint: Lyon Saint-Exupéry’s 2025 summer traffic report (expected September 2025) will reveal whether the airport can close the gap with Marseille. VINCI Airports’ next sustainability report (due February 2026) will also detail progress on Scope 3 emissions reductions.
Key Takeaways
- Lyon is France’s first major airport to hit net-zero emissions, reducing direct CO₂ by 94% since 2013.
- 52% of its traffic is low-cost, a higher share than Paris or Nice, limiting premium-traveler appeal.
- Marseille overtook Lyon in 2024 due to stronger leisure and Mediterranean route networks.
- Sustainability could become Lyon’s growth driver, with hydrogen ground vehicles and carbon-neutral certifications in development.
- Recovery from COVID-19 is uneven: Lyon is at 88% of 2019 levels, while Marseille has already surpassed its pre-pandemic peak.
As France’s aviation sector navigates post-pandemic recovery, Lyon Saint-Exupéry’s dual challenge—regaining traffic share while maintaining environmental leadership—will define its future. For now, the airport’s operators are betting that sustainability will be the differentiator that attracts travelers beyond just price-sensitive flyers.
