Traffic congestion in the capital and smoke from brick kilns are the main reasons for air pollution in Dhaka city, according to the World Bank and the Bangladesh government.
The Ministry of Environment and Forests says that vehicles in Dhaka move 14kmph on an average, which is very slow and causes them to burn more fuel and contribute to air pollution. They say the average speed could come down to 4kmph by 2025 if things do not improve.
A website of the ministry has mentioned this data. The web page is of a government project called Clean Air and Sustainable Environment (CASE), set up with the support of the World Bank to reduce the capital’s smog, produced by brick kilns and vehicles, which has been steadily increasing in recent years. The World Bank and Bangladesh jointly conducted a Country Environmental Assessment and came up with the data.
