Today we flag a press release from Singapore’s environmental agency which announced new targets for air quality as part of their long term plan to reduce annual means for SO2 and PM2.5 (to 15-20 ug/m3 respectively) by 2020. This is relevant for several reasons. Singapore is a major urban state that has to cope with local pollution from industry and mobile sources as well as ambient air quality affected by pollution from its neighbours, including, notably, China. Secondly, because it was the first city in the world to implement congestion charges using electronic toll gates in 1975 and has been a world leader in this field since along with Stockholm and London- indicating a progressive (and successful) approach to addressing the challenges of urban traffic congestion and vehicle emissions.
Key Quotes:
“Singapore today enjoys an air quality better than many cities in Asia and comparable with US and European cities”
“The Sustainable Singapore Blueprint (SSB) was launched in 2009 with the target to achieve an annual mean of 15µg/m3 of SO2 and 12µg/m3 of PM2.5 by 2020”
“will be adopting the World Health Organization (WHO) Air Quality Guidelines (AQG) for particulate matter 10 (PM10), Nitrogen Dioxide, Carbon Monoxide and Ozone, and the WHO AQG’s Interim Targets for PM2.5 and Sulphur Dioxide, as Singapore’s air quality targets for 2020”
“NEA will also increase the reporting frequency of the Pollutant Standards Index (PSI) which measures five key pollutants namely particulate matter PM10, Ozone, Nitrogen Dioxide, Carbon Monoxide and Sulphur Dioxide in the ambient air from once a day to three times daily.”
