Annual Report 2019

057 Transport International Holdings Limited 2019 Annual Report Sustainability Report Care for the Environment The mileage-based oil change scheme brings about a 40% reduction in engine oil consumption and waste oil. Electricity Consumption KMB and LWB consumed around 121,700 GJ (33,820,000 kWh) of electricity in 2019, an increase of 2.5% compared to 2018. The energy intensity, by electricity in total, for the reporting year was 0.044 GJ per square feet (12.2 kWh per square feet). The number of bus stops increased by 0.09% compared to 2018 causing the increase of electricity consumption. We continued to explore environment- friendly initiatives and invested in the latest technologies to minimise energy use and reduce greenhouse gas emissions. Over 100 flood lights were changed to LED flood lights at the rooftop of KMB’s four main depots and LWB’s Siu Ho Wan Depot. After the implementation of these saving measures, the use of energy- saving LED flood lights helped the depots reduce its total electricity consumption by around 10%. In addition, we have changed 22 chiller fan coil units to VRF air-conditioning units at Sha Tin Depot. These installations bring a reduction of electricity consumption in that depot by around 30%. Consumption and Waste KMB and LWB take all practicable measures to reduce the consumption of precious resources and streamline waste disposal procedures. We aim to handle and dispose of all materials in compliance with present laws and regulations and in a responsible manner without creating risks to human health or the environment. Energy Consumption KMB and LWB consumed around 8,285,000 gigajoules (GJ) of diesel oil in the reporting period, including the bus fleets and vehicles other than buses. To reduce fuel consumption, a number of measures have been adopted on the KMB and LWB bus fleets and across its operations: The aircraft-style “Posilock” fuel filling system is used to refuel buses; Ambient sensors are installed on air-conditioned buses to save energy by reducing unnecessary cooling; The use of synthetic gearbox oil extends the oil drain interval from 30,000 to 150,000 km, reducing waste oil by 80%; and including Diesel Oxidation Catalysts, Diesel Particulate Filters, and Selective Catalytic Reduction units to meet the high standards of exhaust emissions laid down by the European Council of Environmental Ministers. In 2019, KMB and LWB emitted around 134 tonnes of particulate matter (PM), 1,862 tonnes of nitrogen oxides (NOx) and 3.15 tonnes of sulphur oxides (SOx) 2 . 1,862 tonnes NOx PM 134 tonnes 3.15 tonnes SOx The latest batch of KMB and LWB buses have been retrofitted with a Selective Catalytic Reduction device, which can reduce the emission of nitrogen oxides, as the ammonia formed from the urea solution converts nitrogen oxides into nitrogen gas and water vapour. As part of our commitment to conserving the environment, KMB and LWB are investing in upgrading the environmental performance of not only the bus fleets, but also the patrol cars. KMB and LWB have introduced 20 electric patrol cars for back-up support and have set up electricity-recharging facilities at the main depots. KMB and LWB have installed electric patrol car recharging facilities in their main depots 2 The emission factors were taken from “Appendix 2: Reporting Guidance on Environmental KPIs” published by the Hong Kong Stock Exchange.
