Hong Kong Airport Services Limited (HAS)
HAS serves 21 airlines at HKIA and operates the largest vehicle fleet in the Group. HAS is committed to reducing carbon emissions from its fleet. In 2011, HAS started the first term of a three-year Ground Support Equipment (GSE) Replacement Programme. In 2017, we will continue with our fleet renewal programme by placing an order for three fuel-efficient lower deck loaders and three light buses.
Our GPS tracking system allows us to efficiently manage our fuel consumption. This year there was a decrease of 2.7% in fuel consumption per flight in comparison to the previous year. We expect additional improvement in fuel efficiency as the GPS tracking system is expanded.
Cathay Pacific Catering Services Limited (CPCS)
CPCS serves 41 airlines and is one of the largest flight kitchens in the world. Through equipment replacement, maintenance and optimisation projects in 2016, 2,500 tonnes of CO2 emissions have been reduced. Some of the initiatives included the installation of more than 2,000 pieces of LED lights, installing two water-cooled chillers to replace older and less efficient equipment. In addition to this, the insulation of chilled pipes, suction pipes, and air ducts has also been replaced in order to reduce lost energy, and optimise the cooling and ventilation demand of the air handling unit in order to avoid over consumption of electricity.
The newly built Phase II facility, which commenced operation in December 2016, is undergoing certification for BEAM Plus Silver for new buildings.
Cathay Pacific Services Limited (CPSL)
CPSL has been operating the Cathay Pacific Cargo Terminal since 2013. With design features to support sustainability, CPSL is committed to support green operations and engage our stakeholders via different initiatives and measures.
Electricity usage was 21.7 kWh per tonnage in 2016, representing a 0.5% decrease against 2015. Some of the energy efficiency initiatives implemented in 2016 included retrofitting over 1,200 lighting fixtures with more energy efficient ones, such as LED lights and induction lamps as well as increasing charging facilities to cope with the growth of electric vehicle use.
Vogue Laundry Services
Vogue Laundry Services employs over 560 staff and serves over 23 airlines, 17 hotels and has a daily output of 251,000 items, equivalent to 71 tonnes of laundry. It is the first laundry in Hong Kong to be certified to the ISO 14001 environmental management standard and the OHSAS 18001 occupational health and safety standard.
Over the past few years, Vogue has been actively exploring ways to reduce emissions through active carbon absorption in the dry cleaning machines and from perchloroethylene, which is a volatile organic compound (VOC) consumed in the dry cleaning process. Consumption of this solvent was decreased by 12% in 2016. Vogue also switched from diesel boiler to a dual-fuel boiler which utilises Towngas and ultra-low sulphur diesel at a 68:32 ratio which has helped to reduce CO2 emissions.
Vogue runs a fleet of 23 vehicles for its collection and delivery services. In 2016, six Euro II trucks were replaced by two Euro V trucks. In 2017, four new Euro V trucks will be added to the fleet and three Euro III trucks will be disposed. Since March 2016, the use of B5 biodiesel has been trialled on one of the delivery routes.
