Clear the Air says:
During Chinese New Year when the PRD and most of Hong Kong was shut down we still had high pollution levels; the contributing prevalent pollutant was Respirable Suspended Particulates (RSP).
But the ocean going vessels were still running as were the local diesel buses and ferries and our coal burning power stations.
The prevailing winds were from the east, not from the PRD.
This decimates the HK Government’s smokescreen babble that 60% of our pollution is coming from China.
Hong Kong still has no Emissions Control Area (ECA) for shipping. In USA the Emissions Control Area is 200 miles from their shorelines. Passing through Hong Kong waters to Shanghai, Shenzhen and our own port we have the largest number of ocean going vessels in the world. They all burn high sulphur bunker fuel. Whereas when they enter USA and Baltic ports they have to switch to low sulphur diesel to comply with the ECA rules. These vessels have dual fuel tanks to allow for this. They could easily switch to a lower sulphur fuel in our waters. Yet again our Government is lacking.
Now, look at the effect Ocean Going Vessels and local shipping has on our environment : Shipping = 31% of RSP, 23% of sulphur and 27% of nitrogen oxides.
