In the dynamic landscape of airport sustainability, real-world examples serve as beacons for actionable strategies. The Project Advisory Group brings a specialised focus on integrating comprehensive strategies, delivery mechanisms, and digital advancements to address airport emissions effectively, highlighting the success stories that can inspire and guide future efforts. 

Each scope of emissions offers different challenges and opportunities for mitigation, as illustrated by these real-world examples: 

• Scope 1 Emissions: Direct emissions from sources that are owned or controlled by the airport. At John F. Kennedy International Airport, the implementation of electric ground service equipment has significantly reduced on-site emissions, setting a precedent for other airports. 
• Scope 2 Emissions: Indirect emissions from the generation of purchased energy consumed by the airport. The use of renewable energy at airports like Amsterdam Schiphol, which has installed solar panels on its terminal roofs, demonstrates a commitment to reducing indirect emissions associated with energy use. 
• Scope 3 Emissions: All other indirect emissions that occur within an airport’s value chain and are the most significant yet most challenging to address, but innovative solutions are emerging. Los Angeles International Airport has initiated programs to reduce emissions from passenger and staff travel by improving public transportation access and incentivising carpooling.

Immediate Actions for Scope 1 and 2 Emissions 

To reduce Scope 1 and 2 emissions, immediate actions include enhancing energy efficiency, modernising vehicle fleets, and transitioning to renewable energy sources. These efforts directly impact an airport’s operational footprint and are critical steps towards immediate sustainability goals. 

San Francisco International Airport has transformed its operations by adopting a comprehensive energy management system that has led to a reduction in energy consumption, contributing to a decrease in Scope 2 emissions. London Heathrow Airport has introduced a series of measures to manage Scope 1 emissions, such as using biofuel for ground vehicles and incentivising airlines to operate cleaner aircraft. 

The Strategic Imperative of Scope 3 Emissions 

While Scope 1 and 2 are within an airport’s control, Scope 3 emissions require a broader approach due to their indirect nature. They include emissions from airline operations, passenger travel to and from the airport, and the entire supply chain. 

Scope 3 emissions present a more complex challenge, yet there are several success stories: 

• Singapore Changi Airport has engaged with airlines and service providers to reduce emissions from the supply chain, such as by optimising flight routes and reducing auxiliary power usage. 
• Copenhagen Airport has implemented a ‘Green Taxiing’ system, allowing aircraft to taxi without engines running, significantly reducing emissions associated with ground movement. 

Strategic Collaboration: 

Stakeholder Incentives: Implementing incentives for stakeholders to adopt sustainable practices, such as using Sustainable Aviation Fuels, can significantly reduce emissions. Zurich Airport offers reduced landing fees for airlines that use aircraft with lower emissions, directly impacting Scope 3 emissions by encouraging airlines to update their fleets. 

Promoting Sustainable Practices: Encouraging behavioural changes in commuting and travel can have a substantial impact on an airport’s overall carbon footprint. 

Digital Transformation: 

Digital technologies are critical in measuring, managing, and reducing emissions, particularly for Scope 3. They offer the precision and agility needed to implement effective sustainability strategies. Utilising digital tools to track and manage emissions, enabling airports to identify and act on reduction opportunities. Helsinki Airport has employed a comprehensive digital system to monitor and manage airport emissions, including Scope 3, resulting in more informed decisions and targeted actions. 

Developing digital solutions to enhance stakeholder engagement and foster a community focused on sustainability. Airports like Dubai International are using digital twin technology to simulate operations and identify areas for emissions reduction. Tokyo Haneda Airport utilises AI-driven systems to optimise energy usage and reduce emissions, paving the way for other airports to follow.
