Annual Report 2024

64 2024 Annual Report Transport International Holdings Limited SUSTAINABILITY REPORT Application on Renewable Energy KMB and LWB have introduced third-generation solar panels on double-deckers to reduce the air temperature inside the bus compartment and supply power to electronic devices in the compartment, thereby reducing fuel consumption. About 30,000 solar panels are installed on buses, at depots and bus stops. Up to 13 million kilowatt-hours (kWh) of electricity will be generated annually, equivalent to the annual electricity consumption of around 4,000 households in Hong Kong, reducing about 9,100 tonnes of carbon emissions. As two franchised bus companies equipped with the largest solar panel systems in Hong Kong, KMB and LWB aim to lead the public transport industry toward a new greener era and promote carbon neutrality. KMB has installed foldable solar panels on the roofs of three bus depots to generate electricity for water boilers. This setup can supply approximately 1,000 litres of hot water at 55 o C per day for our staff members to use for showering. CO 2 Concentration Checks Each year, 80 KMB buses and 15 LWB buses from passenger-intensive routes are selected for data logger measurements of indoor CO 2 concentration. Our buses generally demonstrate compliance with the requirements. Energy Saving KMB and LWB take all practicable measures to reduce resource consumption and streamline waste disposal procedures. We handle and dispose of all materials responsibly in full compliance with applicable laws and regulations, ensuring that no risks are posed to human health or the environment. Fuel To reduce fuel consumption, a number of measures have been adopted throughout the KMB and LWB bus fleets and across all operations: The aircraft-style “Posilock” fuel filling system is used to refuel buses; Ambient sensors are installed on air-conditioned buses to reduce unnecessary cooling; The use of synthetic gearbox oil extends oil drain intervals, reducing waste oil by 80%; and The mileage-based oil change scheme reduces engine oil consumption and waste oil by 40%. Sun Bus also uses Biodiesel B5 for some of its services. Biodiesel B5, the most commonly used renewable fuel in Hong Kong, is produced from animal fat, vegetable oil and other oil through different chemical processes.
