India: The Calcutta High Court in India asked the West Bengal State Government to buy more remote-sensing (RS) units within three months to keep tabs on vehicular emission in Calcutta, Howrah and North and South 24-Parganas. “The state will have to file a compliance report after procuring the machines,” the bench comprising Chief Justice M.S. Shah and Justice K.J. Sengupta ruled.
The orders came during the hearing of a petition filed in 2005 by environment activist Subhash Dutta, who had alleged that trucks entering the city at night were a major source of pollution.
A RS gadget, armed with photo-sensors and pollution checking units, can scan automobile emission without stopping vehicles. The gadget, usually fitted in a van, takes pictures of moving vehicles and simultaneously analyses the content of their tailpipe emission with the help of photo-sensors.
“From November to May, the machine had tested 0.4 million vehicles in the city and the three districts. Around 37,000 vehicles were found to be grossly polluting. Action has been taken against them,” advocate-general Balai Ray said.
The court also directed the state pollution control board to find out whether auto-emission checks were carried out regularly and ordered the police, public vehicles department and the civic authorities of Calcutta and the three districts to provide adequate manpower to the board to perform the job.
