- Electric aviation: Advancing electric and hybrid-electric aircraft technologies to reduce reliance on conventional fossil-fueled engines and significantly reduce emissions during flights.
- Materials innovation: Investing in research and development of lightweight and sustainable materials, such as carbon composites, to reduce the weight of aircraft structures and improve fuel efficiency.
Ensuring Sustainable Ground Operations
- Efficient ground handling equipment: Using electric and hybrid-powered ground handling equipment, such as baggage tugs and aircraft tractors, to minimize emissions and noise pollution on the tarmac.
- Ground power alternatives: Providing aircraft with access to ground power units (GPU) or pre-conditioned air (PCA) systems, reducing the need for auxiliary power units (APUs) and decreasing fuel consumption and emissions during ground operations.
- Waste management: Implementing effective waste separation and recycling systems for catering waste, passenger trash, and other waste generated during ground operations to minimize landfill and promote sustainability.
- Green buildings and infrastructure: Constructing environmentally friendly facilities, such as LEED-certified terminals and hangars, utilizing sustainable construction materials and energy-efficient systems.
- Employee engagement and training: Educating ground operations staff on sustainable practices and encouraging their active participation in environmental initiatives to promote a culture of sustainability within the organization.
Community Engagement and Noise Mitigation
- Noise abatement procedures: Implementing noise abatement procedures, such as restricted nighttime operations, preferential runway usage, and noise insulation programs, to mitigate the impact of aircraft noise on surrounding communities.
- Community outreach programs: Engaging with local communities to create dialogue, provide information on aviation operations, and address concerns related to environmental impact, noise pollution, and other community-specific issues.
- Partnerships with local stakeholders: Collaborating with local businesses, community organizations, and academia to foster innovation, promote sustainable practices, and establish initiatives that benefit both the airport and the surrounding community.
- Investments in noise reduction technologies: Supporting research and development of quieter aircraft technologies, such as next-generation low-noise engines and advanced sound insulation materials, to further reduce the noise impact of aviation operations.
