Hong Kong suffers in smog as pollution problems rise

The New Year has revived old problems for Hong Kong as a murky smog blankets the usually glittering skyline, fuelling complaints from locals and visitors alike, and raising pressure on the government to act.

Tourists expecting to take holiday snaps from the famous Victoria Harbour waterfront have found it hard to distinguish Hong Kong's trademark skyscrapers and mountainous backdrop, while residents are becoming increasingly worried for their own health.

"It's scary," said Julie Crossley, a 39-year-old sales manager from South Africa, visiting the city for the first time with her young daughter.

"I'm scared of what she's breathing in."

For German tourist Harald Gummlich, 60, the pea souper was not what he was expecting. "We're still waiting for blue skies," he said.

The government's new, more stringent, pollution index has revealed the frightening extent of the problem, with high or very high levels of pollution recorded almost every day since it was implemented at the end of 2013.

The Air Quality Health Index (AQHI) came into effect on December 30 and links pollutants to health risks.

Pollution levels have reached the index's top "serious" category on four days so far, under which people are advised not to stay outdoors for a prolonged period.

Hundreds of residents have taken to Twitter, Facebook and newspaper websites to voice their concern.

"Yesterday's pollution was truly shocking - made my eyes sting," Hong Kong based @Alieeeson tweeted Thursday.

Pressure on government

Local campaign groups are hoping the results of the new AQHI system will finally galvanise the government into action.

"It certainly should kick the government into doing something," Clean Air Network chief executive officer, Kwong Sum-yin, told AFP.

Senior environmental affairs officer at Friends of the Earth, Melonie Chau, said the data "can help the public... exert more pressure on the government."

The index monitors the concentration levels of multiple pollutants and measures their health effects through tracking hospital admissions for respiratory and cardiovascular diseases.

Its introduction comes after city leader Leung Chun-ying pledged to make pollution one of his top priorities during his five-year term, with an official report saying it was the "greatest daily health risk" to the city's residents.

Government proposals to reduce emissions include a plan to replace more than 80,000 older commercial diesel vehicles between 2014 and 2019, and a requirement for container ships berthing in the city to use cleaner fuels.

But campaigners are frustrated at what they see as a lack of urgency in implementing the moves.

"We are not very happy with the timeline," Kwong Sum-yin said.

A government scheme to replace catalytic converters on 20,000 vehicles, mostly taxis, kicked off in October last year to lower nitrogen dioxide.

The Clean Air Network is pushing for comprehensive low emission zones on the roads and in Hong Kong waters.

Friends of the Earth's Chau suggested the government should also consider limiting the number of cars on the road when reaches a certain level.

Driving away business

Hong Kong has already fallen to number three in the International Institute for Management Development 2013 World Competitiveness Yearbook, compared to its top spot in 2012—and city lawmakers have admitted that air pollution is driving away businesses.

People looking to expand their careers in Hong Kong are thinking twice about settling down.

"Hong Kong would be a good place to live for a few years, but raising kids? I'd be very cautious about it," Todd Scott, a 37-year-old visitor and head of investment relations from Canada, who just got engaged, told AFP as he walked along the smog-hidden waterfront.

The city's position on the southern edge of the Pearl River Delta—one of China's largest manufacturing centres—makes clearing pollution more challenging, Leung's administration has said.

Winter months in particular see winds blowing in from the mainland, bringing a haze of pollutants.

Levels of PM2.5—tiny particles in the air considered particularly hazardous to health—in Hong Kong were similar to Beijing on Friday afternoon, according to the Beijing based air quality information website aqicn.org.

The Chinese capital is regularly hit by extended bouts of choking, acrid smog, with heavy industries and car-use both among the key culprits.

Commercial hub Shanghai was also blanketed in dense smog in December, delaying flights and spurring sales of face masks.

Air pollution expert Alexis Lau, a professor at Hong Kong University of Science and Technology's Division of Environment, believes Hong Kong will not reach the average annual seen on the mainland, as the city's government introduces its anti-pollution scheme.

"Because of stringent control measures in Hong Kong, the concentration levels should be dropping," he said.

But for some, leaving Hong Kong is the only solution.

Clear the Air campaign group chairman, James Middleton, says he already knows people who have chosen to relocate.

"Quite a lot of people have left (due to air )," he told AFP.

"I would say anybody with children and even those who have asthma will leave."
