National scheme for control areas excluded special administrative region, but local government looks to opt in from 2019
Ships plying the Pearl River Delta, including Hong Kong waters, will have to use cleaner fuel as a part of one of three new national emissions control areas, beginning 2019, the Post has learned.
This follows calls by experts and industry insiders to extend the city’s mandatory fuel switch-at-berth regulation one step further to cover its waters, falling in line with new mainland measures.
The mainland’s Ministry of Transport drew up three emissions control areas – the Pearl River Delta, Yangtze River Delta and the Bohai Economic Rim – in December.
Under that plan, all marine vessels will have to switch to low sulphur fuel while in Chinese waters, regardless of whether they are berthed, unlike Hong Kong’s current law, which is limited to berthed ships. The emissions control areas (ECAs) are pencilled to take effect in January 2019.
The ministry’s edict excludes Hong Kong and Macau from the ECA, but a spokesman for the Environmental Protection Department last night confirmed Hong Kong would be part of it.
“Hong Kong … will collaborate with the relevant mainland authorities to put the ECA in place,” a spokesman told the Post.
Simon Ng Ka-wing, chief research officer at public policy think tank Civic Exchange welcomed the move, as the discrepancy between Hong Kong and the mainland means ships entering Hong Kong can burn cheaper and dirtier fuel until they berth.
“If the cost difference is big enough, ships will switch back to burning a cheaper fuel for the one to two hours until they get to a berth in Hong Kong,” said Ng.
But he questioned how and if the city would comply with emissions targets set by the ministry under “one country, two systems”.
Hong Kong’s fuel-switch law, which came into effect exactly one year ago today, requires ocean-going vessels calling at the city to switch to fuels with less than 0.5 per cent sulphur at berth. About a tenth of all port calls were already doing so voluntarily -before in came into effect.
Similar measures will go in place in Shenzhen this year.
Ng suggested Hong Kong consider pushing the bar further for the region by requiring a stricter fuel target of 0.1 per cent sulphur – a standard that emissions control areas in the US and Europe have.
Arthur Bowring, managing director of the Shipowners Association, supported tighter fuel standards. He said: “It makes no sense for ships to have to change to a distillate fuel when entering Chinese waters, be able to switch back to dirtier fuel when in Hong Kong waters, and then to switch back to distillate after passing through Hong Kong.
“Hong Kong needs to have its legislation ready so that it is able to bring it into force when the requirement enters into force in [the Pearl River Delta].”
Bowring backed a tighter 0.1 per cent fuel requirement but hoped the supply of those fuels at Asian ports would improve. The department said tightening the standard was “impracticable” due the lack of regional availability.
Since the 1990s shipping, along with power generation, has been the largest contributor of toxic sulphur dioxide emissions in Hong Kong.
The department said data showed sulphur concentrations in Kwai Chung, Tsuen Wan and Sham Shui Po were “30 to 50 per cent lower” in the last 11 months than they were in the preceding period.
