This paper analyzes strategies for reducing the environmental footprint of commercial aviation. It argues that converting conventional jet fuel to sustainable biofuels can cut CO2 emissions by up to 80%, and that demand from airlines and consumers is essential to drive commercialization. The paper also examines the role of NextGen Air Traffic Management systems and GPS surveillance in streamlining flight routes and reducing fuel burn. Additionally, it addresses ground-level discharge issues such as de-icing and fueling runoff, recommending centralized de-icing locations and recycling programs. Together, these recommendations frame a corporate social responsibility approach for airlines seeking to minimize their environmental impact.
Because CO2 emissions may be reduced by as much as 80% through the conversion of conventional jet fuel to sustainable aviation biofuels, it is important that airlines begin to implement this conversion across all applicable aircraft models. The commercialization of these fuels will begin once demand is established, and that demand must ultimately come from consumers. For airlines interested in reducing their environmental footprint, a policy of corporate social responsibility (CSR) will help support this conversion process and signal to stakeholders that carriers are committed to reducing toxic emissions.
Airlines should place direct demand upon fuel manufacturers to bring sustainable biofuel products to the commercial market. Demand will create market space for the product and establish airlines as stronger CSR participants within their respective communities. This approach positions carriers as proactive environmental stewards rather than passive actors waiting for regulatory pressure.
Another strategy is for carriers to be more deliberate in how they plan and perform their routes. By implementing more intelligent Air Traffic Management (ATM) systems alongside improved airport infrastructure, congestion in both the skies and at airports can be reduced, which would substantially decrease fuel burn. These systems are already in place in many parts of the country but still require implementation in other regions. NextGen Data Communications systems have been promoted by the FAA, and GPS surveillance is already enabling carriers to streamline their routes (FAA, 2011). However, ATM improvements address only one dimension of the problem — hold-ups at airports can still create lag time and increase fuel burn for jets waiting while other aircraft clear the runway, disembark passengers, or complete boarding. Ground crews must therefore operate more efficiently in their day-to-day airport activities in order to further reduce fuel burn.
Addressing discharges from fueling, de-icing, and other industrial activities is also important for airlines and airports to consider. Airlines and airports must coordinate and work together to develop solutions for discharge issues, because although this type of pollution is less impactful than fuel-burn emissions, it still contributes to an environmental footprint and must be addressed. As Vasilyeva (2009) notes, there are several ways airports could approach this issue: one option is the use of centralized de-icing locations, which could prevent contamination across multiple areas of a facility and keep runoff contained to a specific zone where it can be properly treated and processed; another option is the implementation of a recycling program designed to prevent de-icing solutions from entering groundwater supplies.
