Annual Report 2021

58 Transport International Holdings Limited 2021 Annual Report SUSTAINABILITY REPORT Exploring Renewable Energy and Zero-emission Bus Technologies KMB and LWB strive to explore renewable energy and zero-emission technologies, demonstrating KMB and LWB’s determination to introduce green public transport in Hong Kong. To attach great importance to pursue the Government policy of achieving carbon neutrality by 2050, KMB and LWB introduce the electrification roadmap and plan to install over 22,000 solar panels in order to illustrate its development blueprint for new energy and electric buses. KMB plans to introduce 500 electric buses by 2025, accounting for one-eighth of the whole bus fleet. In the long run, KMB hopes that new-energy buses will be deployed in the entire fleet by 2050 to make Hong Kong a green city. KMB and LWB have 30 single-deck electric buses, together with the 52 double-deck electric buses privately purchased this year. It is expected to have over 80 electric buses by 2022; KMB has introduced the third generation solar panels on double-deckers. The system reduces the air temperature in the compartment by around 8-10˚C compared to a bus without such a system. It supplies power to the fans of the air-conditioning system, thereby reducing fuel consumption. The third generation solar panel bus can save 5-8% of fuel consumption on each bus daily, which is equivalent to reducing about six tonnes of carbon emissions per bus annually. The system becomes a standard feature in new purchase buses; Hydrogen fuel cell bus, alternative new energy technology, is being explored with bus manufacturers for the route with longer driving range. KMB will collaborate with different potential suppliers for hydrogen supply in order to follow the latest Government policy for the pilot trial scheme; and About 22,000 solar panels will be installed on buses, at depots, and bus stops. Up to ten million kilowatt-hours (kWh) of electricity will be generated annually, equivalent to the annual electricity consumption of 2,300 households in Hong Kong, and reducing about 5,400 tonnes of carbon dioxide emissions. As a franchised bus company with the largest solar panel system in Hong Kong, KMB and LWB aim to lead the public transport industry toward the new green era and promote carbon neutrality. 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 promote green public transport in Hong Kong, KMB and LWB lay out an electrification roadmap and install solar panels at bus stops and on bus roofs
