"During proceeding in this case, report was called for from MoEF and in the subsequent proceedings, it has taken a stand that no fresh study was necessary in view of the study ... MoEF relies on that report to contend that there cannot be total ban on use of charcoal as fuel/raw material in the industry," the bench said.
The matter is fixed for next hearing on October 9.
It had asked the ministry to examine the process involved in production of charcoal and submit a report to the tribunal.
The Indian Institute of Sustainable Development had filed a plea alleging that trees were being indiscriminately cut for converting them into charcoal.
The NGO had also sought a ban on the use of charcoal as fuel or raw material in industries across the country.
Noting that the indiscriminate and illegal felling of trees would lead to environmental disaster, NGT had earlier imposed a ban on the cutting of trees without clearance from appropriate authorities.
"There shall be an order of injunction against companies/ authorities from illegally cutting trees in the forest areas in the whole of country to be used for charcoal without obtaining environmental/forest clearance or permission from appropriate authorities," the bench had said.
