Greener Skies Ahead: How International Airports are Championing Sustainability

The aviation industry, often seen as a significant contributor to global emissions, is increasingly recognising its role in addressing climate change. Across the globe, leading airport companies are investing heavily in innovative sustainability initiatives, transforming their operations to minimise environmental impact and foster a greener future for air travel. This article explores three international case studies that showcase best practices in airport sustainability.

Amsterdam Airport Schiphol: Aiming for Emission-Free Operations

Amsterdam Airport Schiphol (AMS) wants to be emission-free by 2030. They’re focusing on electrifying their ground support equipment (GSE), like baggage tractors and boarding buses, and encouraging partners to do the same. This reduces pollution and noise. Schiphol is also trying out new energy solutions, such as the first fully working hydrogen Ground Power Unit (GPU) and a “super battery” that uses iron and salt water, which is safer than lithium batteries. They’re also moving buildings off the gas grid, using geothermal and thermal energy storage. These actions show Schiphol’s commitment to cutting out fossil fuels from its operations

Copenhagen Airport: Forging a Sustainable Aviation Fuel Future

Copenhagen Airport (CPH) is a leader in developing and using sustainable aviation fuels (SAF). They’re part of a group with Danish companies like Maersk, SAS (Scandinavian Airlines System), and Ørsted, working to build a large facility to produce hydrogen and e-fuel. This project aims to produce over 250,000 tonnes of sustainable fuel yearly by 2030, which could replace a lot of the fossil fuel used at Copenhagen Airport. CPH is also involved in “FuelTrack,” a study with SAS and the German Aerospace Centre (DLR), to connect jet fuel properties to aircraft emissions and local air quality. This research will help create cleaner aviation.

Changi Airport Group: Integrating Sustainability into Infrastructure and Operations

Changi Airport Group (CAG) in Singapore takes a complete approach to sustainability, including environmental concerns in its building designs and daily work. The Jewel Changi Airport, for example, collects rainwater and uses energy-efficient glass. CAG also focuses on waste management, recycling concrete and composting horticultural waste. The airport plans to keep its carbon emissions at 2018 levels until 2030, even with more passengers, and hopes to achieve Net Zero by 2050. CAG has also studied climate resilience to prepare for future climate challenges, such as expanding drainage and installing flood sensors.
These three case studies—Amsterdam Schiphol’s drive for emission-free operations, Copenhagen Airport’s leadership in sustainable aviation fuel development, and Changi Airport Group’s integrated approach to infrastructure and resource management—demonstrate the diverse and impactful ways airport companies are embracing sustainability. Their commitments and innovations offer valuable blueprints for the global aviation industry, paving the way for a more environmentally responsible future of air travel.

Decarbonising Airport Operations

$10 BILLION BY 2030:
The Electrical Ground Support Equipment (EGSE) market, including electric pushback tractors and baggage tugs, is projected to reach over $10 billion by 2030, reflecting the growing adoption of electric fleets.

The Drive for Sustainable Aviation Fuels (SAF)

$45 BILLION:
As of early 2023, airlines had made approximately $45 billion in SAF purchase agreements, a significant increase from pre-COVID levels.
