An air quality expert on Tuesday urged the Hong Kong government to enforce tighter sulphur emission rules for ships than those currently being proposed.
The government will present plans next week to improve local air quality, by forcing vessels to use cleaner fuel while in Hong Kong waters.
Lawmakers at Legco's Environmental Affairs Panel will hear that ships would be banned from using fuel with a sulphur content exceeding 0.5 percent by weight from January 1, 2019.
The proposal would bring the city into line with an emission control area in the Pearl River Delta.
But Simon Ng, an independent consultant on air quality and transport issues, said there's room for Hong Kong to do even more.
Ng said there are suggestions from different sectors in Hong Kong to actually tighten the rules further. “From 0.5 which is the requirement for vessels at berth in Hong Kong right now, to go down to 0.1 percent,” he said.
He told RTHK's Richard Pyne that the enforcement of tighter controls will bring a considerable improvement to the air quality in the region.
