Imagine airports of the future where the roar of engines and smell of diesel are replaced by the quiet hum of electric equipment and cleaner air. This isn't just a utopian vision—it's an essential transformation the aviation industry must undergo to achieve its "Fly Net Zero" commitment of net-zero carbon emissions by 2050. The key to this transformation lies hidden in airport ground operations.
Beyond Slogans: The Ground Battle for "Fly Net Zero"
The "Fly Net Zero" initiative represents airlines' pledge to achieve net-zero CO2 emissions by 2050. Ground operations play a crucial role in reducing aviation emissions, with several measures proving effective in supporting this ambitious goal.
Phasing Out "Fuel Guzzlers": The Rise of Electric GSE
Airport ground support equipment (GSE)—including tow tractors, baggage conveyors, and power units—has traditionally been diesel-powered. The industry is now transitioning to electric GSE and biofuels as effective ways to reduce emissions, improve air quality, and enhance working conditions for ground staff.
The International Air Transport Association (IATA) has launched a program to help ground service providers transition to cleaner GSE power more systematically. European studies show that under average EU electricity emission levels, electric GSE reduces CO2 emissions by 48% compared to traditional fossil fuel-powered equipment. Globally, full electrification of GSE could reduce annual emissions by 1.8 million tons of CO2 at 2019 traffic levels.
Electric equipment also reduces noise levels by 5.5 to 8 decibels (A), contributing to better working conditions on the tarmac.
Alternative Paths: Exploring Sustainable Fuels
In regions where electricity supply is unstable or insufficient, complete transition to electric GSE fleets isn't practical. The industry is exploring alternative fuels like HVO100 (hydrogenated vegetable oil) and hydrogen that can reduce lifecycle CO2 emissions.
While fossil fuels remain aviation's primary energy source, sustainable alternatives are being developed as part of the 2050 "Fly Net Zero" initiative. These lower-carbon intensity fuels or their derivatives could also power GSE.
Shared Resources: The Benefits of GSE Pooling
The concept of GSE pooling—where equipment is centrally managed and shared rather than owned by individual ground handlers—optimizes fleet utilization at the airport level. This approach eliminates redundant equipment purchases and helps provide specialized vehicles that are needed infrequently.
Pooling also creates economies of scale in fleet maintenance, reduces spare parts inventory, and simplifies training. Centralized GSE management allows airports to more effectively drive the transition to sustainable energy sources and may facilitate the introduction of autonomous GSE operations.
Green Taxiing: The Future of Ground Movement
Traditional aircraft taxiing requires engine operation, which is inefficient and generates significant noise and emissions. Sustainable taxiing technologies use specialized onboard or ground solutions to move aircraft without starting engines, reducing fuel consumption, emissions, and noise pollution.
This approach also addresses safety challenges associated with running aircraft engines near gates, reducing risks to personnel and foreign object debris (FOD) ingestion.
Environmental Management: Foundation for Sustainability
Ground operations significantly impact the environment through greenhouse gas emissions, noise pollution, waste generation, and water consumption. Implementing an Environmental Management System (EMS) helps ground handlers achieve sustainability goals, track key performance indicators, and meet compliance obligations.
Certified EMS offers multiple advantages, including adopting systematic approaches to sustainability challenges and demonstrating commitment through independent audits.
Waste Not: The Art of Responsible Management
Sustainable operations extend beyond emissions reduction to include comprehensive waste management. Responsible practices cover spill prevention, waste sorting, and recycling materials like GSE maintenance residues and electric vehicle batteries.
People First: The Future of Ground Staff
Ground operations remain labor-intensive, requiring innovative approaches to attract and retain talent in a competitive job market. The industry must transform to offer rewarding careers with development paths that surpass what comparable jobs provide elsewhere.
Safety Above All: The Non-Negotiable Priority
Employee safety, human factors, and standardized training must remain central to operations. Preventing injuries and fatalities requires examining training methods, operational processes, equipment ergonomics, and workplace conditions.
The Talent Challenge: Attracting and Retaining Staff
Ground service providers face severe skill shortages and recruitment challenges. Organizations must comprehensively review their employment and retention strategies, addressing modern priorities like work flexibility, compensation packages, meaningful work, and wellbeing support.
Training Transformation: Developing Future Professionals
Innovative training methods using technology and competency-based approaches are essential to develop skilled aviation professionals. Digital learning options, virtual reality simulations, and training passports that allow skill recognition across organizations can enhance workforce mobility and utilization.
Employee Wellbeing: Core to Sustainability
Research shows that investments in social sustainability positively impact organizational profitability and environmental sustainability. Improved employee satisfaction, productivity, retention, and work-life balance contribute to overall success.
Smart Airports: The AI-Powered Future
Turnaround operations—the most complex and dynamic ground activities—benefit from AI-driven technologies that simultaneously communicate information to all relevant parties. AI can identify objects and vehicles while precisely capturing service timing and delivery.
Implementing industry-standard timestamp systems could reduce global ground handling delays by up to 5%.
Connected Airports: Asset Tracking and Resource Optimization
Modern connectivity enables integration of various operational aspects for greater efficiency. The challenge lies in synthesizing disparate data from cameras, equipment telemetry, and personnel devices into coherent operational insights that drive performance improvements.
Data-Driven Operations: Dynamic Aircraft Data Exchange
IATA has published digital standards that accelerate departure control system (DCS) configuration and approval while enabling real-time updates to applications like electronic flight bags (EFB). These standards reduce potential human errors and improve efficiency in weight and balance data management.
Smart Loading: Digital Load Coordination
Modernizing communication between load planning and control through digital solutions is key to improving loading processes. Modern digital load coordination solutions have helped reduce loading errors by 80% and decrease operational delays.
Autonomous Future: The Rise of Self-Operating Vehicles
Ground handlers are addressing long-term technician shortages by automating routine tasks like vehicle operation. Autonomous GSE improves efficiency in predefined tasks while freeing resources for more critical activities.
IATA has published global guidelines for airport autonomous GSE, establishing minimum capabilities and addressing unique ramp operation challenges.
Robotic Revolution: The Automation Wave
Ground operations present excellent opportunities for robotics applications—from bulk baggage loading to unit load device (ULD) preparation. Properly implemented robotics can streamline tasks, improve working conditions, and potentially enhance employee retention.
Prevention First: Proactive Damage Mitigation
The concept of "enhanced GSE" is well-established in the industry. IATA's 2022 Ground Damage Report details savings and benefits from deploying enhanced GSE while ranking equipment most likely to cause ground damage.
While enhanced GSE benefits are clear, implementation may be slow due to equipment durability and costs. Recognition programs for organizations adopting enhanced GSE could incentivize broader adoption.
Conclusion: Green Ground Operations Within Reach
From electric GSE to waste management, talent development to AI integration, the path to greener airport ground operations requires industry-wide collaboration and innovation. Only through such comprehensive efforts can the aviation sector truly achieve its "Fly Net Zero" ambition for cleaner skies and better journeys.
