The aviation industry's substantial carbon dioxide emissions highlight the urgent need for a transition to net-zero aviation. While sustainable aviation fuels and efficiency improvements are progressing, additional efforts are required, including integrating novel propulsion technologies like hydrogen and electric aviation. Airports play a vital role in this shift and must start planning for the future now. Challenges such as accommodating multiple energy sources like hydrogen and electric power, understanding aircraft demands, and collaborating with stakeholders need to be addressed. Investments in hydrogen infrastructure, electric charging systems, and sustainable aviation fuels are crucial for airports to support the industry's evolving needs. By preparing comprehensive airport master plans and investing in necessary infrastructure modifications, airports can contribute to a more sustainable and environmentally friendly future for aviation.
