Chek Lap Kok will become the greenest airport in the world.
That was the bold pledge of the Airport Authority and its 40 business partners yesterday.
It came as the authority said it has achieved a 10percent reduction in carbon intensity.
The authority rolled out a three-year environmental plan last year to make Hong Kong International Airport a leader in environmental performance by reducing carbon intensity by 25 percent in 2015 from the 2008 emission level.
The 10 percent reduction was achieved through more than 300 green initiatives, including installing LEDs, more environmentally friendly chiller systems, and the introduction of more energy-efficient vehicles.
"Today's pledge to become the world's greenest airport marks a big step forward, putting HKIA at the forefront worldwide, by providing a delightful airport experience and delivering exemplary environmental performance," said authority chairman Marvin Cheung Kin-tung.
It will replace 100,000 lighting applications with LEDs by the end of 2014.
All new transfer saloon cars in the airport restricted area will be electric by the middle of next year, and the whole fleet by 2017.
The authority will invest HK$40 million to install more charging stations in several phases.
The use of auxiliary power units when aircraft are parked will be banned in 2014.
