Carbon-neutral cooling systems
Air and travel service provider dnata has implemented Kaer’s Cooling as a Service (CaaS) to provide chilled water and air to its cargo, catering and support facilities at the Singapore Changi Airport. Kaer retrofitted the cooling systems serving the two facilities with high efficiency, low-Global Warming Potential (GWP) technology and has deployed its data mining, machine learning and carbon monitoring software suite.
Consequently, dnata saw a 54% reduction in energy consumption at its cargo base and a 35% reduction at its catering and support offices. dnata expects to save at least 650 metric tonnes of carbon annually, equivalent to the greenhouse gas emissions from 530 petrol-powered cars for one year. Kaer’s suite of solutions also allows for real-time monitoring and reporting of service levels, energy use, and carbon emissions for ESG (Environmental, Social and Governance) reporting.
Additionally, dnata believes that Kaer’s solutions will help save 1.5 million kilowatt hours of electricity per year. This will complement its existing green power efforts. For instance, dnata’s Singapore facilities are powered by a rooftop power plant comprising 6,500 individual solar panels, which generates over 4,300 megawatt hours of green power each year. As such, dnata cut its electricity-related carbon emissions by 20%.
“We are proud to be an early pioneer in low-GWP refrigerant, making our Singapore operations even more efficient and sustainable. We have plans to expand our CaaS initiatives to additional areas of our operations and look forward to working with our partners to reduce our environmental footprint further,” says Charles Galloway, dnata’s regional CEO of Airport Operations for Asia Pacific.
