As the global aviation industry accelerates efforts to reduce carbon emissions, much of the focus has centred on aircraft technology, sustainable aviation fuel (SAF), and long-term propulsion innovation. While these remain critical, Malaysia Airports believes that meaningful progress must also come from areas within immediate operational control, particularly on the ground.
“At the heart of our approach to building low-carbon, resilient airports of the future is a clear principle: decarbonisation must be practical, scalable, and actionable today,” Malaysia Airports Bhd Managing Director Datuk Mohd Izani Ghani said.
Ground Service Equipment, from baggage tractors to belt loaders and ground power units, remains a significant and often under-addressed source of airport emissions. As passenger traffic and aircraft movements continue to grow, emissions from these operations increase in tandem.
“Unlike aircraft innovation, which depends on long development cycles, reducing emissions from ground operations can be implemented through existing technologies. This presents a critical opportunity for airport operators to take decisive action now,” he added.
A Practical Starting Point for Immediate Effect
KLIA has introduced B20 palm biodiesel for ground service equipment as part of a targeted pilot initiative.
This effort reflects its broader strategy to embed sustainability within day-to-day airport operations, without requiring significant infrastructure overhaul or disruption. By prioritising solutions that integrate seamlessly into existing systems, Malaysia Airports can accelerate implementation while maintaining operational reliability.
The initiative is supported by key ecosystem partners, including Petronas and the Malaysian Palm Oil Board, demonstrating the importance of industry alignment in advancing sustainable aviation practices.
Delivering Measurable Environmental and Operational Value
Since its implementation in February 2025, the transition from B7 to B20 has delivered a 13% reduction in carbon emissions per litre, based on established emission factors.
KLIA’s current utilisation of approximately 42,000 litres of biodiesel has demonstrated that transitioning from B7 to B20 can deliver a 13% reduction in carbon emissions per litre, based on established emission factors. Applied at scale, such reductions can contribute meaningfully to an airport’s overall carbon footprint.
Beyond emissions reduction, B20 biodiesel also enhances equipment performance through improved lubricity and a higher cetane number, contributing to more efficient combustion and reduced engine wear. These benefits are particularly relevant in high-frequency airport environments, where operational reliability is critical.
This dual outcome on environmental impact alongside operational performance, is essential in ensuring that sustainability initiatives are both viable and sustainable over the long-term.
Scaling Through Industry Collaboration
Decarbonising airport operations is not the responsibility of a single stakeholder. It requires alignment across airlines, fuel providers, regulators, and ground handlers.
KLIA’s ground handling partners such as Menzies Aviation, Ground Team RED and Pos Aviation have participated in the pilot, reflecting growing confidence in it as a practical alternative fuel.
“Malaysia Airports sees its role in this ecosystem as an enabler, bringing together stakeholders to test, validate, and scale solutions that can be replicated across the network and beyond,” he added.
A Model Built on Local, Scalable Solutions
In Malaysia, palm-based biodiesel provides a readily available, cost-effective alternative to conventional diesel, aligned with national priorities under the National Energy Transition Roadmap. By leveraging domestic resources, the transition can be accelerated without introducing significant cost pressures or supply constraints.
While each market will have its own pathways, the underlying principle remains consistent: solutions must be practical, scalable, and contextually relevant to drive real impact.
From Ambition to Action
The aviation industry has set clear long-term climate targets. The immediate priority is translating these ambitions into tangible action.
Ground operations present one of the most immediate opportunities to achieve measurable emissions reductions. By focusing on areas within direct operational control, airport operators can accelerate progress while laying the foundation for broader transformation.
This approach is central to Malaysia Airports’ commitment to building low-carbon, resilient airports of the future, where sustainability is embedded not only in long-term strategy, but also in everyday operations.
“Decarbonisation does not begin in the skies. It begins with the decisions made on the ground and the willingness to act on them today,” he added.
