Hong Kong officials continue to legislate for switching out old diesel engines on road vehicles, singing their own praises and splashing public funds in the process. Yet Hong Kong’s air quality remains extremely poor – a simple look outside the window suffice to dissatisfy.
Air quality on a Sunday afternoon. PM2.5 readings are very high, at 150-170.
The number of vehicles on the roads on Sunday is the least in the week, in addition to the consideration of all the work that the officials proclaim to have done in reducing vehicles emissions. The PM2.5 particles, on the other hand, don’t lie. Their continued presence points to shipping emissions as the real major source of pollutants in Hong Kong.
The Northeasterlies at the Northeast brings emissions from Yantian; the Northwesterlies at the Northwest brings emissions from Shekou; Southerlies at the South brings emissions from ships passing through and into Hong Kong.
Hong Kong urgently needs to legislate and enforce an emissions control area for shipping. It remains to be seen if the city’s officials will take real action.
