The quality of air in Seoul hits its best level since compiling data in 2001!
The amount of particulate matter recorded at the end of November last year was 52 micrograms per cubic meter, reaching its lowest level since Seoul City began compiling the data in 1995. The quality of air in Seoul has gradually improved, with the amount of particulate matter standing at 55 micrograms per cubic meter in 2008, 61 micrograms per cubic meter in 2007 and 71 micrograms per cubic meter in 2001.
43 fuel stations for natural gas buses were built amid aggressive PR efforts on safety and conflict management
To further improve the quality of air, Seoul City plans to replace all buses in the city with buses powered by compressed natural gas by the end of 2010. In addition, the city plans to reduce emissions of greenhouse gas and other pollutants by introducing eco-friendly, high-performance electric and hybrid vehicles.
As part of these efforts, Seoul City built 43 fueling stations for natural gas buses after replacing diesel-powered buses with the eco-friendly vehicles. The 43 fueling stations can handle about 10,000 natural gas vehicles a day. In 2010, Seoul City plans to build four new fueling stations for natural gas buses.
A bus powered by natural gas is more environmentally clean than other fuels such as gasoline and diesel. For a bus operator, a natural gas bus saves fuel costs. For a customer, the natural gas bus is good for the air quality because of the absence of any lead or benzene content.
However, building a fuel station for natural gas buses has been limited because such facilities are categorized as dangerous. Despite the limitation, Seoul City built a fueling station for natural gas buses at the city’s headquarter building in central Seoul with the aim of showing the safety of the facility.
Since 2006, Seoul City has expanded fueling stations for natural gas buses more than twice a year. Currently, fueling stations in Seoul can handle a total of 9,790 natural gas vehicles a day. If four more fuel stations are built this year as planned, the capacity will rise to 10,470 vehicles a day.
