How Airports Are Growing Without Blowing Their Climate Goals

Airports worldwide are pursuing the paradox of hitting net-zero targets while accommodating passenger growth, and many believe the answer lies in building less. Vancouver International (YVR), Amsterdam Schiphol, and Heathrow are using digital twins and analytics to squeeze more capacity from existing assets, avoiding emissions and costs of new construction. Where expansion is unavoidable, operators like Aena, San Diego International, and YVR design in efficiency, renewables, and modularity from the start. However, Scope 3 emissions, dominated by flights, remain the biggest challenge, with aviation accounting for roughly 2.5% of global carbon emissions.
