Annual Report 2021

60 Transport International Holdings Limited 2021 Annual Report SUSTAINABILITY REPORT Emissions Reduction KMB and LWB adopt the latest technologies to reduce roadside emissions and maintain the good air quality in bus compartments. We have a number of measures, including using Near Zero Sulphur Diesel, renewing the models and upgrading older buses by retrofitting exhaust treatment devices, such as Diesel Oxidation Catalysts, Diesel Particulate Filters, and Selective Catalytic Reduction units, to meet the high standards of exhaust emission laid down by the European Council of Environmental Ministers. As part of our environmental protection commitment, KMB and LWB make continuous investments in upgrading the environmental performance of bus fleets and patrol cars. KMB and LWB have introduced electric patrol cars for back-up support and set up electricity-recharging facilities at the main depots. 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 in compliance with applicable laws and regulations, and we do it in a responsible way without posing risks to human health or the environment. Fuel 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 reduce unnecessary cooling; The use of synthetic gearbox oil extends the oil drain interval to reduce waste oil by 80%; and The mileage-based oil change scheme reduces engine oil consumption and waste oil by 40%. Electricity We continue to explore environment-friendly initiatives and invest in the latest technologies to minimise energy use and reduce greenhouse gas emissions. Besides our one-off LED light replacement and continuous housekeeping measures, we have dynamically adjusted our electricity consumption pattern in accordance with the latest operation scales, including adjustment of illumination time of parking depots and optimisation of equipment used to support our facilities’ operation duration. We cooperate with a power company to install Solar Photovoltaic Systems consisting of more than 3,500 solar power panels at depots, bus termini and bus shelters to strengthen the application of renewable energy and reduce greenhouse gas emissions. Green Measures in the Office The Green Office concept drives both the design and the renovation of our premises. We run our air-conditioning system at 25.5°C to align with the Government’s Action Blue Sky Campaign and save energy. Operating hours have also been rearranged to reduce energy waste during non-office hours. High-efficiency air conditioning units are installed in all newly renovated offices. Solar film will be installed on building windows to isolate the outside heat effect and reduce electricity consumption and the demand for air-conditioning. We have also set up recycling arrangements for used toners, plastic materials and used papers. Waste Reduction KMB and LWB are committed to good waste management through responsible storage and disposal of waste, recycling and reusing resources whenever feasible. Significant types of waste generated in our operations are reported as follows: Waste Water As responsible corporate citizens, KMB and LWB are committed to reducing water consumption and properly treating effluents before discharge. Our depots are equipped with ten automatic waste water treatment systems handling 400 cubic metres per day. The water used for bus washing was collected and recycled, reducing total water consumption at depots by around 4%. Newly set up rainwater collection and recycling system has been introduced in some of our satellite depots. We would continue to install more rainwater collection and recycling systems in some other bus depots in the coming years so as to increase water consumption saving.
