Commentary by Christine Loh in S China Morning Post:
Earlier this month, Beijing released tighter air quality objectives for the mainland. Hong Kong officials didn't seem to know this was going to happen. It put pressure on them to come to a decision on Hong Kong's own objectives after two years of dithering.
Our officials' objective has shifted from health protection to infrastructure protection.
It is this attitude that got them into trouble in the first place. They have left the cleaning up so late that catching up will require many urgent measures, such as banning old polluting vehicles, pedestrianising urban areas, regulating ships' emissions, switching energy sources, and more. If the next administration retains the same mindset, it too will keep on fudging rather than pushing for aggressive pollution reduction.
