Clear skies over Hong Kong Island as protester stop traffic reaching Central

Danny Cheng: "This proved vehicles should be banned from busy districts asap, also bus companies should use hybrid buses like London asap....."

Pro-democracy protesters may have inconvenienced commuters yesterday, but by blocking roads in some of the city's busiest areas they also managed to clear the skies.

The air quality was better than usual for a weekday in Causeway Bay, Mong Kok and Central, where the protests are centred, according to Environmental Protection Department data.

The health risk posed by air pollutants in the three areas was "low", as opposed to the usual "high", the department's website said. And it remained "low" all day yesterday, except in Mong Kok, where it changed to "moderate" at 3pm.

Kwong Sum-yin, chief executive of the Clean Air Network, said the link was clear.

"The roadside stations mainly detect traffic emissions. They are less susceptible to air pollution from the Pearl River Delta region. So it is quite clear that the protests blocking road traffic have improved the city's air quality," Kwong said.

In Causeway Bay, the level of nitrogen dioxide, an air pollutant emitted by vehicles, more than halved - from 125 micrograms per cubic metre of air at 10pm on Sunday night to about 60 micrograms after 9am yesterday. In Mong Kok, the level fell from 126 micrograms at midnight on Sunday to 70 micrograms after 9am.

And in Central, pollution levels dropped after protesters began occupying Harcourt Road on Sunday afternoon - going from about 110 micrograms per cubic metre of air at 7pm on Sunday to about 60 micrograms after 9am yesterday.

A department spokeswoman confirmed that reduced traffic in the areas had helped lessen air pollution levels at the roadside monitoring stations.

Kwong said the temporary improvement showed the effectiveness of a low-emissions zone proposed by the government, in which polluting vehicles would be banned from busy districts.

Let's transform Des Voeux Road into green zone

Danny Cheng: "Yes, Brilliant idea, so we can ride bike to work for sure! Des Voeux Road Central need to be transform asap; And when can the Bus Company start using hybrid buses!? Please do something for our city asap now"

Busy Des Voeux Road Central in the heart of Hong Kong's business district should be transformed into a bus-free zone so that pedestrians and office workers can breathe cleaner air, the Institute of Planners has suggested to the government.

The vision was laid out in a joint study by the institute, City University, the Civic Exchange think tank and the MVA Hong Kong transport and planning consultancy firm.

Under their plan, the 1.5-kilometre section of Des Voeux Road Central, stretching from Pedder Street to Morrison Street, would be closed to all vehicles except necessary traffic such as banks' security vans, delivery vans and emergency vehicles.

Bus routes would be diverted to Connaught Road and nearby streets so that the tram would become the only form of public transport allowed along Des Voeux Road Central.
