Sadly, the glorious clear days and magnificent nightly views of Hong Kong's incredible skyline, which have blessed us these past two months, may soon end.
According to the Hong Kong Observatory and a Civic Exchange air pollution specialist speaking on RTHK, these clear skies have more to do with the southern winds than any anti-pollution actions on the part of Hong Kong.
To most people this seems a reasonable explanation for our clear-sky luck. In the debate over Hong Kong's air, reasonable explanations have been in short supply of late.
Both government and civic activists often forget that providing an explanation to Hongkongers on the causes, effects, and ways of lowering air pollution is not simply churning out information for the unwashed masses to absorb uncritically.
I have no doubt that most Hong Kong people would support tougher enforcement of fuel standards on commercial vehicles and heavy equipment, and improved standards on ship and aircraft emissions. A daytime truck ban in the city centre wouldn't have much problem gaining support either and, of course, local power plants would need to be up to European standards. These measures are concrete and people understand the benefits.
But it is no secret that many of our results in curbing air pollution are due to picking the low hanging fruit and a natural result of our economic development.
