The government should cut the number of diesel-powered vehicles on the streets, and make the remainder less polluting, to protect pedestrians now the World Health Organisation has classified diesel fumes as a cause of cancer, lobby groups say.Thursday, 14 June, 2012, 12:00am
Shooting the messenger is never a good idea, especially when people's health is at stake. Yet that is what the Chinese government seems intent on doing to US diplomatic missions, which since last year have been issuing data on the smallest and most harmful air pollution particles, PM2.5, in three cities.9 Jun 2012 - 12:00am
Mounting pressure on the shipping industry to reduce harmful exhaust emissions has forced a global shipowners' lobby group to call for a set of unified international standards.
The Baltic and International Maritime Council (BIMCO) said unified standards were needed to avoid the sort of controversy troubling airlines.2 May 2012 - 12:00am
Early last year, officials said that the proposal to increase the first registration tax on private cars was aimed at tackling air pollution. Legislators who didn't initially support the idea had to be convinced that the financial burden on new car owners was a small price to pay for reducing the health burden of the community.20 Feb 2012 - 12:00am
Hong Kong's clean-air targets will be toughened for the first time in a quarter of a century from 2014, but they will still fall short of World Health Organisation standards.18 Jan 2012 - 12:00am
Nothing is more evident than roadside air pollution. We can see and smell when it is poor and our lungs can tell us how bad it is. The Environmental Protection Department's annual update showing the worst-ever levels in Hong Kong's busiest districts therefore comes as little surprise.13 Jan 2012 - 12:00am
The municipal environmental authorities in Beijing will release air pollution readings for PM2.5 - fine particles with a diameter less than 2.5 microns - before the Lunar New Year, Xinhua reports.6 Jan 2012 - 12:00am
The ban on idling engines could improve air quality by at least 30 per cent, according to a test conducted a day before and a day after by the South China Morning Post.
However non-compliance as a result of lax enforcement and polluting vehicles could also offset these potential benefits.23 Dec 2011 - 12:00am
In the early 1990s, Hong Kong power companies were criticised for not doing enough to curb their pollutant emissions. Alongside local green groups, our mantra was 'less coal, cleaner fuels', which compelled the government to set tighter standards of emissions for our power suppliers.8 Dec 2011 - 12:00am
Roadside air quality has worsened in the first quarter of this year. Data from the Environmental Protection Department showed that the air pollution index reached very high levels 34 per cent of the time, compared with 11.9 per cent of the time during the first quarter of 2010 - a threefold increase.13 May 2011 - 12:00am
So, after 14 years of talk and negotiation, Hong Kong finally has a law regulating vehicles parked with engines running. It has been watered down so much by transport interest groups it will not have much impact on air pollution, the reason we have been having this discussion for so long.8 Mar 2011 - 12:00am
Last month I was sitting in Tokyo's Haneda Airport looking out over the city's skyline.
The perfectly clear blue skies, with unlimited visibility, were such a wonderful sight.
Later, as the plane took off, Mount Fuji was clearly visible in the distance.5 Feb 2011 - 12:00am
How hard is it to tackle Hong Kong's air pollution problem? Some actions would go a long way. Our power and transport companies need to use clean fuel and our buildings have to be more energy-efficient. Making this happen is a matter of will and funding. We are not a poor community, nor are we known to be a people afraid of a challenge.25 Jan 2011 - 12:00am
I would like to respond to Terry Scott's letter ('Officials do not seem to care', December 13).
The government attaches great importance to improving our air quality. To this end, we have been undertaking a host of measures to tackle our major air pollution sources and making joint efforts with the mainland to improve the air quality of the whole Pearl River Delta region.22 Dec 2010 - 12:00am
Environmental watchdogs from Hong Kong and Guangdong are compiling a report on proposals to reduce air pollution levels in the Pearl River Delta ('Report due on quality targets for delta's air', November 17).
Pollution levels are getting worse and these watchdogs have to come up with ways to solve the problems that we face.24 Nov 2010 - 12:00am
