Chief Executive Donald Tsang urges Hong Kong people to support the clean-air initiative. He will meet his Guangdong counterparts next month to take stock of the clean-air measures the two places have taken.

Speaking on RTHK's Letter to Hong Kong today, Mr Tsang said local air is more polluted than it was 10 years ago, and the Government is working hard to deal with the issue quickly.

Noting 80% of the pollution comes from the Pearl River Delta, Mr Tsang said the Government and Guangdong authorities have joined forces to establish an emissions reduction scheme.

"Our common goal is to significantly cut emissions of four major pollutants by the year 2010," he said.

In Hong Kong, the Government has cracked down on smoky vehicles, and encouraged taxis and minibuses to switch to liquefied petroleum gas. Steps have also been taken to make power plants more environmentally-friendly.

Everyone plays a role

"Yet much more needs to be done. I share the public's frustration that there is no quick fix, or no magic formula to clean up our air immediately. But each and every one of us can, and must, play a role to reduce air pollution."

He said if each Hong Kong person reduces their electricity consumption, power generators would burn less fuel and emit less pollutants.

"When it comes to energy conservation, everyone can pitch in. All of us can make choices every day that have an impact on the environment. "

He urged people to raise the air-conditioner temperature to 25.5 degrees, turn off idling car engines, and take public transport as often as possible.

"Consumers can shun goods with volatile organic compounds, such as hair spray and air fresheners. And you can easily opt for electrical appliances with Energy Efficiency Labels."

Noting a Dress Down in Summer campaign has been launched in the Government, Mr Tsang said he was glad that many in the private sector have followed suit.

"The business community has taken the lead by promoting a Clean Air Charter, which the Government wholeheartedly endorses. But, because 80% of Hong Kong's air pollution comes from across the boundary, I urge all investors in the Pearl River Delta to observe the Clean Air Charter and adopt cleaner manufacturing practices there, as well as here."

The Chief Executive also urged developers and architects to come up with plans that are better suited to the city's climate, with more efficient air circulation.

Another danger

"We all know the dangers of drinking, smoking and overeating. So, we should also be aware of the dire consequences of poor air quality - not just for ourselves, but also our children and grandchildren. If left unchecked, air pollution will drive away talent, stifle investment, reduce tourism, and ultimately choke economic growth.

"Hong Kong people are known for their skill and determination in solving problems and overcoming daunting challenges. I am sure we can win this battle against air pollution. If other cities have done it, so can we.

"The key is to get as many members of the community as possible involved in making simple and smart choices that do not impact greatly, if at all, on our way of life."
