Driven by industry-wide efforts to improve efficiency and mitigate environmental impacts, airports continue to incorporate sustainable practices into the design, construction and operations of facilities. 

The path to achieving sustainability at airports lies in proactive planning and the strategic integration of innovative technologies throughout a project lifecycle.

• Incorporating sustainability at the outset. Early and consistent integration of sustainability practices ensures they become a core component of the project. This proactive approach allows for the seamless incorporation of sustainable measures, resulting in more cost-effective outcomes. One effective strategy is to have sustainability experts collaborate with different airport divisions to ensure all decisions emphasize sustainability. This method leads to more cohesive and impactful outcomes tailored to the unique needs of technical aviation professionals.

• Considering lifecycle costs. Upfront costs for sustainability and resiliency features may be higher, but over time, the total organizational costs can be much lower. Proactively developing an analysis of the long-term cost-savings at the outset of the project is crucial for obtaining buy-in from airport leadership, the public and local policymakers. By demonstrating the long-term financial benefits and cost savings associated with sustainable technologies, aviation professionals can demonstrate the need for investment.

• Collecting data. Continuous data collection set against baseline figures allows airports to adjust goals or techniques as necessary and report back to airport leadership and policymakers on progress toward fulfilling commitments. This process also can help airports identify projects and facilities that lead to the highest emissions, driving future strategies for mitigation. Ratings systems, such as Envision or LEED provide important guidance on sustainability metrics and how airports can meet them.  

Advancements in Technology

The future of sustainability at airports will continue to evolve as new and innovative technologies become available. Investments in microgrids, or localized power grids, can reduce transmission loss, enhance energy management systems and provide backup power during outages, ensuring continuous operation of critical airport functions. 

Innovative water management practices, such as the use of recycled water for non-potable applications, are becoming more prevalent. The use of treated wastewater for cooling towers and restroom facilities significantly reduces potable water consumption and saves millions of gallons of water annually.
As the aviation industry moves toward electric and hydrogen-powered aircraft, airports are developing the necessary infrastructure to support these innovations. This includes installing charging stations and upgrading facilities to accommodate new energy sources, thereby supporting the growing fleet of electric ground support equipment and preparing for future advancements in aircraft technology.

A Changing Landscape

As the aviation industry continues to innovate and embrace sustainable practices, the future holds great promise for further advancements in airport infrastructure. By remaining committed to proactive planning and adopting cutting-edge technologies, we can look forward to creating more efficient, environmentally friendly airports that benefit both the industry and surrounding communities.
