In response to the challenges posed by COVID-19, WWF-Cambodia launched a project in Cambodia’s tourism sector, focusing on energy efficiency and carbon emission reduction in hotels and restaurants. Acknowledging that outdated cooling systems contribute significantly to high energy consumption in some hotels, WWF-Cambodia commissioned this study to explore how the introduction of new equipment can lower electricity bills and CO2 emissions.

The study examined in detail the cooling systems in five hotels and identified significant savings from upgrading chillers and air conditioning systems. Indeed, hotels can save up to $100,000 per year on their cooling system bills by upgrading their systems, with a payback time as short as three years. This represents a significant opportunity for the sector.
