Narita International Airport Corporation is taking significant steps towards sustainability, led by Takeshi Ishiguro, Chief of Sustainability. The airport is actively working on decarbonisation projects, including replacing halogen and fluorescent lights with LEDs, with a goal to convert all aviation lights to LED by 2030. Ishiguro is overseeing initiatives for vehicle decarbonisation, including establishing infrastructure for electric, hydrogen, and fuel conversion. The airport is also focusing on promoting solar power generation and incentivizing the use of sustainable aviation fuel to reduce emissions. The Sustainable Narita 2050 initiative outlines the airport's commitment to achieving carbon neutrality through various sustainability measures. Ishiguro emphasizes the importance of unity among stakeholders in tackling decarbonisation challenges. The airport has been progressing well in its decarbonisation strategy, with a focus on increasing solar power generation and transitioning to sustainable energy fuels. Regarding hydrogen, Narita Airport currently refuels with grey hydrogen from an off-site station, but plans to shift to green hydrogen production through water electrolysis using solar power. Ishiguro's leadership underscores the airport's dedication to environmental responsibility and innovation in the aviation industry.
