The global conservation body WWF is calling on the Airport Authority to halt public consultation on the planned construction of a third runway until more information is revealed.
The group met the authority last week to demand more details. It wants studies on issues, such as the likely impact on Chinese white dolphins and the area's marine ecosystem. The request was denied, WWF said.
WWF Hong Kong's chief executive Eric Bohm dismissed the process of public consultation, which will continue until September 2, as a propaganda exercise with a foregone conclusion.
'The magnitude of the taxpayers' investment and [the project's] scale warrants a better basis for analysis than this case of smoke and mirrors by the Airport Authority,' he said.
William Yu Yuen-ping, head of WWF Hong Kong's climate programme, slammed the authority for not revealing the projected increases in aviation emissions.
The authority announced the expansion plan last month, saying the existing runways will reach full capacity by 2020.
