On November 3, Airport Authority Hong Kong (AA) and its airport business partners celebrated Hong Kong International Airport’s (HKIA) achievement in reducing carbon intensity by 25.6% per workload unit by 2015, as compared with the 2008 level. This achievement surpassed the original target of reducing carbon intensity by 25%, set in 2010. The AA and its business partners have also announced a new 10% reduction target as compared with 2015 level for the five-year period from 2016 to 2020.
     Since 2010, the airport community has completed more than 400 carbon reduction initiatives to achieve its carbon intensity reduction goal. These include installing over 100,000 LED lights at HKIA and improving cooling systems, as well as introducing electric vehicles and charging facilities. An online carbon audit system has also been developed for the AA and its participating business partners to monitor and report on progress. In 2013, HKIA received the Airport Carbon Accreditation "Optimisation" certificate from the Airports Council International in recognition of its carbon emissions management and reduction efforts.
     Currently, the number of participating business partners has increased to more than 50. To achieve the new goal, the AA and the airport community will implement more measures to enhance energy efficiency, including optimising the energy consumption of the air-conditioning systems and enhancements to the cooling and lighting systems.
     Some of the key initiatives for the AA include the replacement of over 80,000 LED lights at Terminal 1 to further enhance energy efficiency, optimising the energy consumption of Midfield Concourse, and the conversion of apron high-mast lighting to LED light sources. The AA will also collaborate with local and foreign universities to develop smart and quick charging solutions for electric vehicles, and seek to achieve the best energy efficiency with cloud-based analytic energy management system. Meanwhile, business partners of the airport community will optimise energy consumption of the air conditioning system and install energy-efficient lighting to work towards the reduction goal.
