Timely and accurate data is invaluable to decision makers. Currently, Thailand has one of the best ambient air quality monitoring systems in the world. The ambient air quality is gathered from a nationwide network. Daily reports, as well as monthly or annual, can be readily produced. Reporting is also quick to react on sudden changes on levels of particular matters.
The Public Disclosure of Industrial Pollution (PROPER) approach in Indonesia aims at reducing industrial pollution via public disclosure. It was developed and tested by the country’s National Pollution Control Agency (BAPEDAL) together with the World Bank.
Various programs that aim to minimize air and noise pollution from the transport sector are being implemented. These programs are usually conducted in areas with large and dense population or areas where flow of traffic and people are heavy. The aim is to improve air quality via the application of command and control schemes or market based instruments in the transport sector. Interventions could also involve introduction of alternative technologies (e.g. electric buses) or arrangements (e.g. limitation on number of vehicles via coding schemes).
Industrial growth is the primary driver for the rapid development of China. However, the growth experienced in the industrial sector was accompanied by heavy consumption of resources, resulting to generation of pollution. Interestingly, large firms were not solely responsible for the generated pollution in the country. Small and medium-scale enterprises (SMEs) located in villages and towns also contributed to the pollution problem. The pace of development and the growth of the industries put pressure in China’s resource use. Air pollution also is a threat due to coal combustion.
The transport sector is identified to be one of the contributors of air pollution in Dhaka. In particular, two-stroke auto rickshaws or baby taxis were identified as one of the strongest contributor. It was also found out that this vehicle emits a hydrocarbon; volatile organic compound; and particulate matters. The program to achieve better air quality was kicked-off by conversion to Compressed Natural Gas (CNG) and the startup of fueling stations in October 2001. In December 2002, the Ministry of Communications issued a ban on two stroke baby taxies.
The practice aims to provide cost-effective air monitoring program, especially in the scenario of budget and resource constraint.
