Introduction
Environmental sustainability has become a central focus in aviation, and that extends to ground handling operations. Airports and ground service providers are implementing eco-friendly practices to reduce emissions, conserve resources, and mitigate the environmental impact of servicing aircraft.
This article examines how ground handling is going green – from electrifying support vehicles to reducing waste – and looks at the initiatives driving sustainable transformation on the ramp. By adopting cleaner technologies and practices, ground handlers are contributing to aviation’s broader goal of carbon neutrality while also improving local air quality and working conditions.
The Push for Greener Ground Operations
Aviation’s climate goals (such as the industry pledge to reach net-zero carbon emissions by 2050) require action not just in the air but also on the ground. Traditionally, ground handling activities have relied on diesel-powered equipment and processes that generate emissions and waste.
For example, a busy airport ramp might have dozens of diesel baggage tugs and belt loaders expelling exhaust, and ground power for aircraft was often provided by onboard auxiliary power units (APUs) burning jet fuel. These activities contribute to carbon emissions, air pollution (particulate matter and NOx) at airports, and noise.
Recognizing this, there is a concerted effort to make ground operations more sustainable. In fact, IATA has explicitly included “embedding sustainability – people, planet, and prosperity – in all activities” as one of three top priorities for ground handling in recent years.
Sustainable ground handling practices not only reduce environmental impact but can also yield cost savings (through energy efficiency) and improve safety (electric equipment tends to require less maintenance and has lower fire risk from fuel, etc).
Key avenues of sustainability in ground handling: reducing carbon emissions via electrification and cleaner energy, minimizing waste and pollution, and improving resource efficiency.
Electrification of Ground Support Equipment (GSE)
Replacing diesel-powered GSE with electric alternatives is at the heart of sustainable ground handling. Ground support equipment – including pushback tractors, baggage tugs, belt loaders, catering trucks, and cabin power units – historically ran on fossil fuels. Electric GSE (eGSE) now offers a viable, zero-emission replacement for most of these.
The benefits of eGSE are significant. An IATA-commissioned study in Europe found that electrically powered GSE produce 48% less CO₂ emissions on average (accounting for power generation emissions) than equivalent equipment with internal combustion engines. On a global scale, if all GSE were electric, it’s estimated that ground handling CO₂ emissions could be reduced by 1.8 million tonnes per year. This is a substantial contribution to aviation’s climate goals. Additionally, electric GSE are quieter – noise levels are 5.5 to 8 dB(A) lower, which improves working conditions for ramp staff and reduces airport noise pollution for surrounding communities.
Airports around the world are transitioning their fleets. Many new baggage tractors and belt loaders being purchased are battery-electric models. For instance, Delta Air Lines has made large investments such that some of its hubs have nearly all-electric ramp vehicle fleets. In Europe and Asia, several major ground handling companies have committed to aggressive electrification targets.
Menzies Aviation, one of the largest global ground handlers, announced that as of 2023, 17% of all its motorized GSE worldwide is electric, including 42% of its equipment in Europe.
This progress put Menzies ahead of its goal to have 25% of its global GSE fleet electric by 2025. The company ultimately aims for a 100% zero-emission GSE fleet as part of its net-zero 2045 strategy.
Airports are facilitating this shift by installing the necessary infrastructure: charging stations and upgraded power supply on the ramp.
For example, some airports have designated charging zones near gates where electric tugs can plug in between flights. Portable battery units are also used in some cases to recharge GSE in remote areas without fixed chargers.
There are challenges – initial costs of electric GSE are higher, and airports must invest in electrical infrastructure. Charging logistics need to be managed so that vehicles don’t run out of power during critical operations. However, many ground handlers report that electric GSE has lower maintenance and fuel costs, which offset the investment over time. Additionally, governments and airport authorities often provide incentives (grants, reduced fees) for adopting cleaner technology.
In addition to battery-electric, some airports are testing alternative fuels for GSE as interim solutions. This includes biofuels or renewable diesel for existing diesel engines, and even hydrogen fuel cell technology for GSE. For example, hydrogen fuel cell baggage tugs have been trialed that emit only water vapor. These alternatives can cut emissions while using current equipment designs, but the long-term trend strongly favors electrification due to its energy efficiency and dropping battery costs.
One often overlooked piece of GSE is the ground power unit (GPU) and pre-conditioned air (PCA) units that supply electricity and air conditioning to parked aircraft. Traditionally, if a gate didn’t have fixed electrical and air hookups, aircraft would run their APUs (small jet engines in the tail) to power lights, ventilation, and avionics during turnarounds – burning fuel and emitting CO₂.
Deploying electric mobile GPUs and PCA units means the aircraft’s engines can stay off, eliminating those emissions. Many airports are now requiring gate operations to use either fixed electrical ground power or mobile electric GPUs instead of APUs. This has a huge impact: shutting off APUs can save hundreds of kilograms of fuel and several tonnes of CO₂ per flight. Airports like Oslo and Heathrow have APU usage restrictions for this reason.
Overall, electrification of GSE and using external electrical power for aircraft on the ground are among the most effective sustainability measures in ground handling. They directly cut scope 1 emissions (direct emissions from operations) for ground handling companies and scope 3 emissions (indirect, via reduced APU use) for airlines. As grid electricity itself becomes greener with more renewable energy, the carbon footprint of electric GSE will drop even further over time
Beyond vehicles and fuel, sustainable ground handling also involves reducing waste and managing resources wisely. Several initiatives illustrate this;
Balancing Sustainability and Operational Demands
Implementing sustainable practices in ground handling must be balanced with maintaining operational performance and safety. Fortunately, many green initiatives yield operational benefits too (as we’ve seen with electric GSE having lower maintenance downtime, or digital processes improving efficiency). However, challenges exist, such as electrification targets.
Sustainable ground handling is no longer a niche experiment; it is rapidly becoming the new normal in aviation services. Through electrification of equipment, smarter energy use, waste reduction, and industry collaboration, ground handlers are shrinking their environmental footprint. These changes align with the broader decarbonization of aviation and demonstrate that environmental responsibility can go hand in hand with efficient operations.
Every electric baggage cart put into service, every diesel engine turned off, every recycling bin filled with plastic that will be reprocessed – each is a small victory that adds up to significant progress. The ramp of the future will feature fleets of quiet, zero-emission vehicles zipping between planes, personnel trained not just in safety and efficiency but also in sustainability, and an operational mindset that values resource conservation.
For passengers, many of these changes are invisible – they may simply notice the air is a bit cleaner when boarding via stairs, or that there isn’t the smell of diesel around their aircraft. But as part of the flying experience, knowing that even the servicing of their flight is being done in an eco-friendly manner can enhance an airline’s brand and customer satisfaction.
In sum, sustainable ground handling is a critical piece of the green aviation puzzle. The technologies and practices are available today and continue to improve. With commitment from all stakeholders, the goal of fully eco-friendly ramp operations is within reach. This will ensure that as air travel grows, it does so responsibly, with ground operations contributing to a more sustainable aviation industry for generations to come.
