Third runway at Chek Lap Kok is key to Hong Kong's sustainable growth
Joe Ng says any airport expansion must respect the environment
The current discussion around the proposed three-runway system at Hong Kong International Airport is focused on the potential impacts on the environment.
The environmental lobby and those living near the airport have raised valid concerns about the potential impact on local ecology, noise disturbance and air quality. But there is also the validity of the overall need for a third runway to consider.
Not only is Hong Kong International Airport a major transport hub, it is also vital to the city's continued prosperity as an economic powerhouse. This brings benefits to everyone in Hong Kong, not just airline passengers or cargo shippers.
It also generates vital benefits through connections between cities and markets that enable foreign direct investment, business development and other spillover benefits that help Hong Kong thrive. Currently, aviation is worth HK$88.9 billion to Hong Kong, representing 5.5 per cent of gross domestic product.
But what is the cost to the environment of these vital benefits? Undoubtedly, aviation, like every other industry, has an environmental impact and currently accounts for 2 per cent of global man-made greenhouse gas emissions. But it is also an industry that is fully committed to reducing this impact. Airlines are investing heavily in the very latest technology. The Airbus A380, already serving Hong Kong, is one of the world's quietest large aircraft.
New aircraft designs, including the Boeing 787 and Airbus A350 XWB, utilise advanced materials such as carbon fibre, making them lighter, reducing fuel consumption and carbon dioxide emissions by up to 28 per cent compared to their predecessors. Overall, aircraft are now 70 per cent more fuel efficient than the early jets, with lower emissions. New aircraft are also progressively quieter than those in service even a decade ago. Through technological advances, the industry has managed to reduce overall noise by 75 per cent since the early 1960s. In October, aviation became the first global sector to have its post-2020 carbon dioxide emissions regulated by the UN - something the industry had been calling for since 2008 - and had pledged to achieve carbon-neutral growth by 2020.
