Phnom Penh Airport

The important investments realized in the last years in Cambodia have enabled to double the overall capacity at Phnom Penh and Siem Reap airports to 10 million passengers.

After those expansion works, Phnom Penh airport, capital of the country, has now 31.000 sq. m. of surface area to meet the demands of rapidly growing air traffic in Cambodia. In 2019, the airport was awarded by the CAPA Centre of Aviation, best Asia Pacific regional airports for smaller airports category (fewer than 10 million annual passengers).

In 2024, the airport reached the level 3 of the ACA decarbonation program.

The ACA program requires the monitoring of the airport carbon footprint and the implementation of actions to reduce the footprint over the years. To achieve the Level 3 milestone, the airport has invested heavily and deployed multi-pronged initiatives, including:

• Commissioning efficient chiller systems for the central air conditioning
• Replacing all light sources with LED technologies
• Putting in place automatic systems to reduce and optimize the energy consumptions in the main buildings
• Awareness campaigns across the airport community encouraging specific behaviors towards carbon management and reduction

Additionally, and as part of the airport’s Stakeholder Engagement Program, it has included third parties, such as restaurants, fuel suppliers, airliners, into the initiative, extending its benefits to the entire airport community and beyond.
