Annual Report 2020

68 Transport International Holdings Limited 2020 Annual Report Sustainability Report 118 tonnes 1,635 tonnes 3.09 tonnes Particulate matter Nitrogen oxides Sulphur oxides PM NOx SOx Emissions Reduction Environmental Bus Fleet We are committed to creating a better environment and minimising the climate-related impacts by investing in eco-friendly buses that meet the strict exhaust emission standards of the European Council of Environmental Ministers. At the end of 2020, there were 442 Euro VI buses (including three Euro VI diesel-electric hybrid buses), 2,846 Euro V buses, ten battery-electric buses and eight supercapacitor buses in the KMB fleet, and 209 Euro V buses and four battery-electric buses in the LWB fleet. In collaboration with our suppliers, we have been replacing older bus models with the latest, more energy-efficient bus models to enhance the endurance and environmental performance of our bus fleets to achieve “zero emission” on the road. The average age of the KMB bus fleet has become 6.60 years, while that of LWB has become 6.04 years. Exploring Renewable Energy and Zero-emission Bus Technologies KMB and LWB strive to improve environmental performance by exploring various renewable energy and zero-emission technologies, which shows KMB and LWB’s determination to introduce green public transport in Hong Kong. KMB has introduced some double-deckers with solar panels to its fleet. The system reduces the air temperature in the compartment by around 8-10˚C compared to a bus without such a system; KMB and LWB are exploring the use of an electric bus (“eBus”) with a 324 KWh Lithium Iron Phosphate battery power pack capable of delivering 200km of zero-emission bus transport; and KMB has introduced the “gBus”, the supercapacitor-powered 12-metre air-conditioned single deck bus. The gBus is characterised by long working hours and frequent start-stop duty cycles, as the supercapacitor can be recharged more quickly and undertake many more charging/ discharging cycles. The gBus can be powered up by an overhead pantograph or a plug-type charging port in the depot. Checks on CO 2 Concentration Each year, 80 KMB buses and 15 LWB buses from passenger-intensive bus routes are selected for a data logger measurement of indoor CO 2 concentration. Our buses generally demonstrate compliance with the requirement. To strive for eBus development, KMB has set up electricity-recharging facilities at main depots
