Net-Zero Airport Definition

A Net-Zero Airport is an airport that achieves a balance between the greenhouse gases emitted and those removed from the atmosphere, resulting in no net carbon emissions. Most targets align with achieving net-zero by 2050.

Strategies to Achieve Net-Zero:

Electrification of Ground Support Equipment.
Adoption of Green Taxiing and Autonomous Airside Operations.
Renewable energy integration (solar, wind, geothermal).
Energy-efficient terminal design and operations.

Importance:

Net-zero strategies improve community relations, meet environmental regulations, and strengthen airport brand positioning in sustainability-conscious markets.

CAST Application

CAST supports the journey to a Net-Zero Airport by simulating operational improvements that reduce emissions across all airside processes. From stand allocation to pushback procedures and vehicle routing, CAST can quantify the contribution of each measure to the airport’s net-zero targets, helping decision-makers prioritize the most effective steps.

With this glossary we would like to give short, basic explanations and definitions for important and frequently used terms in the fields of Analysis, Runway and Terminal Capacity Assessment and Airport Simulation/Allocation. These are based on our experience of practical application in the industry. We would be happy to provide you with more detailed definitions and further explanations. Please feel free to contact us.
