The National Board of Revenue is all set to impose a green tax on about 2,500 polluting industrial units to force them to cut back on pollution. The industrial units will have to deposit 1.0 percent of their receipts in the state exchequer.
The surcharge, introduced this year, is a part of the government's move to encourage industries to set up effluent
treatment plants and to make them aware of the harmful effects of their activities on the environment.
The Buriganga and other rivers around Dhaka, including the Turag, the Bangshi, Tongi Khal, the Balu and the Shitalakkhya, have become highly polluted due to the dumping of wastes from tanneries, dyeing factories and other industries as well as households.
Among them, the Buriganga, the lifeline of Dhaka, is the most polluted river, having zero oxygen level in its waters for nine months a year because of the toxic tannery wastes from Hazaribagh.
