How airports are growing without blowing their climate goals

illuminem summarises for you the essential news of the day, reviewed by our editorial team. Read the full piece on Skift or enjoy below:

🗞️ Driving the news: Airports pursuing both passenger growth and net zero are increasingly betting on building less
• Vancouver International, Amsterdam Schiphol and Heathrow use digital twins, virtual models tracking how passengers, luggage, aircraft and assets move, to find capacity within existing infrastructure
• Schiphol saved €82,000 and 375 tonnes of CO2 annually in a single terminal through this approach
• YVR targets net-zero emissions from its own operations by 2030, covering buildings, fleets, generators, refrigerants and electricity

🔭 The context: Where expansion is unavoidable, operators including Spain's Aena, San Diego International and YVR are designing in efficiency, renewables, electrification and modularity from the outset
• San Diego's Terminal 1 cut embodied carbon by 30% and saved $58 million by reducing steel use, according to reports
• Airport Carbon Accreditation now covers 661 airports, but only 30 have reached the top Level 5

🌍 Why it matters for the planet: Scope 3, dominated by flight emissions, remains the sector's largest and hardest footprint, with aviation responsible for roughly 2.5% of global carbon emissions and a greater warming effect once non-CO2 impacts are counted
• Avoided construction is a genuine gain, embodied carbon in concrete and steel is permanent once poured, but an airport that meets its own net-zero target while enabling more flights has reduced the emissions it reports, not the emissions its growth produces

⏭️ What's next: Collaboration across airlines and suppliers is emerging as the central theme, with Finland's Finavia operating a network model that financially subsidises smaller airports, and operators positioning themselves as facilitators of others' decarbonisation

💬 One quote: "In many cases, the most sustainable building is the one you don't have to build" — Wendy Avis, environment director, Vancouver International Airport.

📈 One stat: Only 30 of 661 accredited airports have reached the top tier of Airport Carbon Accreditation.
