How Airports Can Meet Sustainability Goals
It’s no surprise that U.S. airports play a major role in carbon emissions and environmental impact. According to the International Council on Clean Transportation (ICCT), the U.S. had the highest emissions related to passenger air travel in 2019, followed by the European Union and China.
To help U.S. airports reduce their carbon emissions and promote environmental sustainability, the U.S. Department of Transportation’s Federal Aviation Administration (FAA) and airport and environmental stakeholders in the aviation industry launched the Airports Climate Challenge in April 2022. The goal is net-zero emissions and a net-zero aviation system by 2050.
Getting on Board With Sustainability
Regardless of size or location, airports nationwide are increasingly integrating sustainability commitments into their operations and infrastructure. Sustainability is a key theme that’s making aviation cleaner, quieter, more efficient, and more resilient.
While many airports have set long-term sustainability goals, there are short- and medium-term actions that can be taken to move closer to the sustainability ambitions of net-zero emissions and a net-zero aviation system. Here are some effective actions for airport operations personnel to consider that can have an immediate environmental impact.
Investing in Renewable Energy Sources
Switching to renewable energy sources is one of the most effective ways airports can reduce their carbon footprint. Solar, wind, and geothermal energy installations are becoming more common at major airports.
By investing in renewable energy, airports can cut down on their reliance on fossil fuels and decrease their greenhouse gas emissions. Considering the large land area many airports have, on-site solar farms can be a practical solution for generating clean energy for powering daily operations, such as lighting and HVAC systems.
Enhancing Energy Efficiency
Energy efficiency is crucial in minimizing an airport’s environmental impact. With terminal buildings, baggage handling systems, escalators, HVAC systems, and lighting consuming massive amounts of power, airports can adopt energy-efficient systems to manage usage.
LED lighting, automated temperature control, and smart energy management systems are all effective solutions for lowering energy consumption. Adopting these energy-efficient technologies can help airports significantly optimize energy usage, reducing waste and enhancing sustainability efforts.
Reducing Carbon Emissions With Electric Vehicles
Ground operations, including baggage transport, passenger shuttles, and maintenance vehicles are typically powered by fossil fuels that contribute to an airport’s carbon emissions. Transitioning to electric vehicles (EVs) for ground support can help airports reduce emissions and create a healthier and quieter environment for workers, travelers, and the community.

Minimizing Waste and Promoting Recycling
From plastic bottles to food packaging, airports generate substantial amounts of waste. Implementing waste segregation and recycling stations in terminals is a simple but effective solution for reducing waste.
Another effective approach is implementing a recycling program, which includes composting food waste and recycling materials such as paper, metal, and plastic. Additionally, airports can work with vendors to minimize single-use plastic usage and encourage reusable or compostable alternatives.
Sustainable Water Management
Water consumption at airports is substantial. Implementing water-efficient fixtures, such as low-flow faucets and toilets, can significantly reduce water usage in terminals.
Airports with large green spaces can incorporate sustainable landscaping practices to reduce water usage. For example, airports can plant native and drought-resistant plants to minimize the need for irrigation. Managing water resources wisely can help airports lessen their impact on local water supplies and reduce operating costs.
Engaging Stakeholders and Travelers in Sustainability
Without engaging stakeholders, employees, travelers, and the community, reaching sustainability goals isn’t possible. Offering incentives for public transportation or carpooling to the airport is a simple solution for reducing an individual’s carbon footprint.
Developing education and awareness campaigns can inform travelers and the community about an airport's sustainability initiatives and encourage them to participate. By fostering a culture of sustainability, airports can build public support for eco-friendly initiatives, making long-term sustainability goals easier to achieve.
