Sustainability
Sustainability Is Reshaping Airports Worldwide
Sustainability in aviation is no longer an abstract aspiration, it’s a strategic priority and existential challenge for the airport industry. As airports grow to serve rising passenger demand, environmental impacts intensify across multiple dimensions: energy and carbon emissions, resource consumption, noise and air quality, water and waste management, and local community effects. These pressures are compounded by mounting regulatory expectations, social scrutiny, and economic constraints.
Airports are pivotal nodes in the global air transport system. While aircraft emissions dominate the climate footprint of air travel, emissions from airport operations, ground transport access, and energy consumption are significant and visible. Industry frameworks now distinguish between direct emissions from airport operations (Scope 1), indirect emissions from energy usage (Scope 2), and emissions created by others at the airport (Scope 3).
What Are the Main Sustainability Challenges for Airports?
Sustainability at airports is easier to commit to than to operationalise. The challenges below describe where the difficult work actually sits, across emissions, energy, resources and resilience, and what helps to address it.
Climate-Resilient Infrastructure and Long-Term Investment Planning
Airports operate infrastructure with long life cycles, high capital intensity and complex approval processes. As climate risks intensify and regulatory frameworks evolve, infrastructure planning must account for resilience, adaptability and long-term carbon performance. This underlines the importance of integrating climate risk assessments, sustainable construction standards and future-proof investment strategies into master planning and procurement processes.
Decarbonizing Airport Operations
Airports are under pressure to achieve net-zero emissions while continuing to expand infrastructure and services. Regulatory bodies and industry alliances — including European airports — have set ambitious targets for carbon neutrality, with some operators planning to make terminals carbon neutral within the next few years.
Sustainable Aviation Fuel (SAF) Scaling
SAF — a crucial lever for reducing life-cycle carbon emissions — represents one of the most promising yet challenging pathways to decarbonization for the entire aviation ecosystem. Its adoption is held back by production capacity, cost premiums, supply chain maturity, and regulatory uncertainty. Airports can play a strategic role as distribution hubs and stakeholders in SAF value chains, but clear frameworks and incentives are still evolving.
Resource Efficiency and Renewable Energy
Energy usage represents one of the largest operational emissions sources at airports.
Transitioning to renewable energy sources like solar and wind, improving energy management systems, and optimizing heating, cooling and lighting are immediate opportunities for both carbon reduction and cost savings.
Waste and Water Management
Beyond energy, airports face increasing expectations to rethink waste management — from
reducing single-use plastics and expanding recycling programs to redefining food service models and minimizing water footprint. Innovative initiatives around food donation, composting, and waste-to-resource partnerships illustrate what’s possible when airports integrate sustainability into everyday operations.
Community and Regulatory Pressures
Environmental advocacy groups and local stakeholders are mobilizing stronger oversight of airport development plans, particularly when growth trajectories conflict with broader climate commitments. This underlines the importance of transparent engagement, integrated planning, and aligned governance between airports, regulators, communities and national targets.
How Do GATE Members Address Sustainability at Airports?
In practice, sustainability at airports advances through specific projects more than through targets. The projects on this page show how GATE member companies have addressed the challenges above at airports in Europe and other regions.
Zero Emissions at the Gate: Dynell's Hydrogen GPU Takes Off at Schiphol
Every aircraft requires ground power while at the gate – traditionally a source of significant emissions. Dynell's DHM 090 Hydrogen Ground Power Unit changes this equation. Developed with partners Zepp.solutions and KES, the unit converts hydrogen into electricity through an electrochemical process, with water as its only byproduct. Currently undergoing real-world testing at Amsterdam Airport Schiphol as part of the EU's TULIPS program, the DHM 090 delivers reliable 400 Hz and 28 VDC power for 7–9 aircraft turnarounds per day before refueling – proving that hydrogen is a viable path to zero-emission airport ground power.

Smart Energy, Net-Zero Airports: Schneider Electric's Climate-Neutral Airport Solutions
Airports worldwide face mounting pressure to cut emissions while keeping operations running 24/7. Schneider Electric helps airport operators meet this challenge through advanced digital energy management systems and microgrid technologies that make airport infrastructure smarter, safer, and significantly more sustainable. At Vancouver International Airport (YVR), Schneider Electric's integrated approach enables real-time energy monitoring, renewable integration, and resilient power supply – laying the groundwork for net-zero airport operations and demonstrating how major hubs can decarbonize without compromising reliability.

Hydrogen on the Apron: Hamburg Airport Tests Zero-Emission Baggage Tug
At Hamburg Airport, a conventional gas-powered baggage tractor has been retrofitted with a hydrogen hybrid drive system by HTM (Hydro Technology Motors) – and is now operating under real apron conditions. Rather than replacing vehicles outright, this approach demonstrates a scalable retrofit path for existing airport fleets. The multi-month real-world test, conducted as part of Hamburg Airport's Net Zero 2035 strategy and the EU-funded BSR HyAirport programme, explores how hydrogen propulsion could decarbonize ground vehicle fleets across airports in Europe – one converted tractor at a time.
