Sustainable air hub blueprint

Cutting energy use and switching to clean power

We are making our airports cleaner and more energy-efficient by maximising renewable energy use and reducing overall power consumption.

This includes:

• increasing solar power deployment across airport facilities to generate clean energy

• switching to cleaner airside vehicles, with all new light vehicles to be electric from 2025

• improving building efficiency through better design, cooling and lighting systems

• leveraging on low-carbon electricity imports to further reduce our carbon footprint

• exploring the feasibility of an on-site waste-to-energy facility to promote circular use of resources and reduce landfill waste

Building a Sustainable Aviation Fuel (SAF) ecosystem

We are laying the foundation for a thriving SAF ecosystem in Singapore to help airlines reduce flight emissions.

This involves:

• setting a national SAF target and levy to guide adoption and keep costs transparent for travellers

• centralising SAF procurement, aggregating demand to reap economies of scale

• encouraging SAF production in Singapore and across the region to grow the supply chain and create new opportunities for green aviation

• improving flight efficiency through ongoing fleet renewal and operational improvements

More efficient air traffic management

We are improving how air traffic is managed so that flights can take more direct and efficient routes, reducing fuel use and carbon emissions.

This includes:

• using advanced demand-capacity balancing, including expanding air traffic flow management solutions and integrating meteorology with air traffic management to improve flight coordination and management

• enhancing performance-based navigation so aircraft can fly more precise routes that save both time and fuel

• optimising gate-to-gate flight trajectories to enhance runway efficiency and increase fuel savings

You can learn more about the actions taken in Air traffic management sustainability initiatives.

We have introduced several policies to drive tangible actions.

These include:

• setting domestic aviation emissions reduction targets to spur collective action among the Singapore aviation community

• introducing a national SAF target to encourage SAF production and kick-start adoption in Singapore and the region

Two key programmes were introduced to foster collaboration, cooperation and capability building among stakeholders:

• S$50 million Aviation Sustainability Programme to fund sustainable aviation projects

• establishment of the International Centre for Aviation Innovation (ICAI) to drive innovation across all aspects of aviation, including:

  • air traffic management

  • airport operations

  • advanced air mobility

  • aviation sustainability

Proper planning and supporting infrastructure are necessary for aviation sustainability initiatives to be implemented smoothly.

Projects include:

• designing and developing the new Changi Airport Terminal 5 to achieve the Building and Construction Authority’s Green Mark Platinum Super Low Energy standard

• working with partners to study the technical feasibility of hydrogen adoption and infrastructure requirements

Equipping aviation workers with the skills, training and mindset needed through:

• identifying new and emerging sustainability-related job roles through a tripartite effort involving the government, companies and unions

• upskilling and job redesign initiatives

• working with Institutes of Higher Learning to:

  • embed aviation sustainability resources and content into the curriculum

  • stimulate interest through sustainability-linked internships and learning journeys

Singapore is committed to participating in partnerships and collaborations across various levels to advance sustainable aviation.

Our partnerships and collaborations include:

• the International Civil Aviation Organization (ICAO)
  Singapore is involved in various ICAO capacity-building initiatives such as Assistance, Capacity-building and Training on Carbon Offsetting and Reduction Scheme for International Aviation (ACT-CORSIA). Under ACT-CORSIA, Singapore provides technical experts, who will work together with the requesting states to provide on-site training, and to follow-up on the preparation and implementation of the requesting States’ CORSIA monitoring, reporting and verification (MRV) system.
  
  Singapore is also actively involved in the Committee on Aviation Environmental Protection (CAEP) and its various expert groups. CAEP assists the ICAO Council in formulating new policies and adopting new Standards and Recommended Practices (SARPs) related to aviation environmental impact.

• forming multilateral and bilateral partnerships to drive sustainable aviation, such as the ASEAN Sustainable Aviation Action Plan
  To promote international collaboration in sustainable aviation, CAAS has signed cooperation arrangements with multiple countries. These arrangements are aimed at collaborating and exchanging information to advance sustainable aviation, in key areas such as policy and regulation, industry development, infrastructure planning and provision, and workforce transformation. Some key areas include knowledge exchanges in areas such as the ICAO Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), as well as coordinating research and development, test bedding and trialling Sustainable Aviation Fuel (SAF).

• establishing the Asia-Pacific Sustainable Aviation Centre with partners to develop capabilities for sustainable aviation policy research specific to the Asia-Pacific region
  Launched in July 2025, APSAC is a Singapore centre with a regional mission. It aims to support APAC to advance sustainable aviation through policy research, collaboration and capacity building, with strong support from key partners from the aviation, energy and green financing sectors in its Advisory Council. APSAC has jointly developed a foundational capacity-building course ‘Growing Aviation Sustainably’ with the Singapore Aviation Academy.
