BEIJING - July 28th, BBC
China has admitted it could introduce further emergency measures to cut air pollution during the Olympic Games. One expert said that could mean taking 90% of Beijing's private cars off the streets at particularly bad times.
Figures show pollution levels have been relatively high over recent days - on some days thick smog is severely reducing visibility. The BBC found one pollutant at the Olympic Village was three times higher than the recommended level on Monday. China has already introduced a series of measures to curb air pollution, including taking half the city's cars off the roads.
Polluting factories surrounding Beijing have also been told to close.
But an article in the state-run China Daily gave details of the further, stricter measures that could be introduced.
"More vehicles could go off the roads, and all construction sites and some more factories in Beijing and its neighbouring areas could be closed temporarily," a front-page article said. This was confirmed by Professor Zhu Tong, of Peking University, who advises the Beijing government about air pollution. He confirmed that 90% of the city's private cars could be taken off the roads under these stricter controls.
Any emergency measures would be introduced 48 hours in advance of very bad pollution, he said. "There is a chance... that we cannot meet the air quality standards so stricter measures are needed," said Prof Zhu. He maintained that the current measures had reduced pollution, but not by enough to guarantee good air quality every day.
China promised to clean up its air pollution for this summer's games, but figures show it still does not meet the toughest World Health Organization standards.
Small particles in the air - PM10 - are a particular worry. WHO guidelines say 50 micrograms per cubic metre is the standard to aim for, but Beijing rarely hits that target. At the Olympic Village on Monday, the BBC found the PM10 level was at least 145, while at the BBC office it was 134.
Separately on Monday, Greenpeace published its assessment of China's efforts to clean up Beijing for the Olympic Games. It says, that overall the attempt to get rid of pollution has created a "positive legacy" for the city and should be commended.
"Greenpeace found that Beijing achieved, and in some cases surpassed, original environmental goals," the report says. But it said in other areas, including air quality, Beijing had not met targets, and has had to bring in short-term measures. "Beijing could have adopted clean production measures more widely across the municipality to speed up the improvement of air quality," the report says.

26 innovations secure 'Green Olympics' achievement
BEIJING, July 27 (Xinhua) -- Beijing has applied a wide range ofgreen technologies and clean energy in building venues and facilities for the upcoming Olympic Games, according to a press briefing here on Sunday.
These advanced technologies, including water recycling, rainwater utilization, solar photovoltaic power generation, and reclaimed water source heat pumps, could help environmental protection while encouraging technology innovation, said Tan Xuxiang, deputy director of Beijing Municipal Planning Commission. Altogether 26 innovations were achieved during the Olympic preparation period, he added. To fulfill the bidding pledge of "Green Olympics," the Games' organizers used environment-friendly materials in building key venues such as the Olympic Green, the Olympic Village and the Olympic Forest Park, Tan said. A total of 31 competition venues and 45 training venues have been built for the impending Games. They are mainly located in five areas, namely the Olympic Green, the west community, the northern scenic spot area, the university area, and the east community.
Special attention was paid to the protection of cultural relics throughout the construction of all Olympic projects, Tan said, citing the protection and repair of ancient architecture in the Olympic Green zone, such as the Goddess Temple and the Dragon King Temple. Both the location of Olympic stadiums and the selection of competition routes have avoided important water resource conservation areas and natural reserves, he said. The official said that the concept of "Green Olympics" mainly has three implications -- a green environment, "green stadiums" with energy saving features, and the "green consciousness" for the public that endorses environmental protection and a healthy lifestyle. All efforts relating to the promotion of "Green Olympics" will leave a precious heritage for Beijing when the Games are over, he added.

Beijing launches anti-pollution traffic control measures
BEIJING, July 20 (Xinhua) -- Sunday saw the start of two months of vehicle control in Beijing to ease traffic pressure and improve air quality for the Olympic Games. Beijing's drivers found much fewer vehicles on the road and a much smoother drive in the morning, partly because it was on the weekend but largely because of the vehicle restrictions. According to a short-term traffic rule effective from July 20 through Sept. 20, vehicles with even and odd plates run on alternate days in the metropolis, which boasts 3.29 million vehicles.
Traffic was smooth during the morning peak hour. From the Liuliqiao Bridge on the southwest third ring road to Beitucheng on the northeast of the north third ring road, a normally one-hour-plus drive took only half an hour in the morning. Lin Fengjiang, who has an odd-number car plate, said he opted for the bus because of the restrictions. "It's ok with me. The bus runs very fast today. It's even more time-efficient than driving a car," said the office worker.
Yao Zhenping, assistant to the general manager of the Beijing Public Transport Holdings Group, said monitoring showed that more than 95 percent of the buses reached the stops according to the timetable, something that was impossible on congested roads. The city authorities said the restriction, along with an earlier ban on the use of vehicles which failed to meet emission standards, would drive 2 million cars off the roads to ease traffic and improve air quality for the Games. With the restriction rule, an additional 4 million people were expected to resort to the public transport system due to the vehicle use control, according to the city government.
The restriction rule was applied to both vehicles which registered in Beijing and non-Beijing vehicles which drove on Beijing's streets during July 20-Sept. 20 period. But those vehicles which were used to transport fresh vegetable into Beijing were free of the rule, said the city government. Car emissions have been considered as one of the major sources of air pollution in Beijing. The atmospheric pollution in Beijing is caused by a combination of sulfur dioxide, nitrogen dioxide, carbon monoxide and particulate matter, which largely came from exhaust emissions, environmentalists said.
He Kebin, a professor at the Department of Environmental Science and Engineering of Tsinghua University, said almost all major indicators of Beijing's air quality had met the requirements of the Olympic Games except for the indicator of the inhalable particulate matter. "Vehicles contribute more than 50 percent of the pollution caused by the inhalable particulate matter, so the restriction of vehicle use is the most effective way to solve the problem," said He. Environmental experts estimated that the vehicle-use restriction and the ban on the use of vehicles which failed to meet emission standards will cut car emission by 63 percent, or about 118,000 tonnes of pollutants, for Beijing in the next two months.
The vehicle-use restriction won applause from Beijing residents. According to a survey conducted by the Beijing Social Facts & Public Opinion Survey Center, 94.8 percent of the respondents supported the rule, which was 5.9 percentage points higher than last year's approval rate. During Aug. 17 to 20 of 2007, Beijing had carried out a four-day test run of even-odd traffic control to clear the city's air. Also on Sunday, Beijing started implementing another two-month-long measure to ease traffic pressures and reduce air pollution -- the change working hours.
The city government said it encourages people to work flexible hours or work at home if possible. Working hours for companies will be set from 9 a.m. to 5 p.m. Public institutions will begin work at 9:30 a.m., one hour later than normal. Shopping malls will open no earlier than 10 a.m. and stay open longer, until 10 p.m. or even later. Over the past years, Beijing has been working aggressively in a bid to improve its oft-criticized air quality. Beijing municipal government said it had poured more than 140 billion yuan (20.5 billion U.S. dollars) since 1998 into more than200 projects dedicated to improving the city's air quality.
Such efforts have paid off. The Beijing Environmental Protection Bureau said the city's air quality had been continuously improving since 1998. The "blue sky" days, or days with fairly good air quality, for the entire year of 2007 had jumped to 246 from 100 recorded in 1998, said the bureau. In 2007, the densities of sulphur dioxide, carbon monoxide, nitrogen dioxide and particulate matter in Beijing's air were 60.8percent, 39.4 percent, 10.8 percent and 17.8 percent lower than in1998, according to the bureau.

Windpower to provide a fifth of Olympics power supply
BEIJING, July 20 (Xinhua) -- A wind power plant has become operational in suburban Beijing, considered a major step towards making 20 percent of the power supply to the city's Olympic venues during the games wind-generated.
The Guanting Wind Power Plant, beginning operation on Saturday, would not only help fulfil Beijing's promise of a "green Olympics", but symbolize the first-ever large-scale employment of wind power generation project in the Chinese capital, said a spokesman for the project. With an installed capacity of 64,500 kilowatts, the plant has 43 domestically developed wind power units at work.
Since its first unit went into operation on Jan. 20, the plant has supplied 35 million kWh of "green power" to Beijing. It is expected to supply 100 million-kWh electricity per year, enough to meet the daily demand of 100,000 households. The power plant could help cut yearly emission of carbon dioxide by 100,000 tonnes and save 50,000 tonnes of coal each year. The Beijing Olympics opens on Aug. 8.
