New Delhi: The government is working to install a single-window mechanism for faster regulatory clearances for coal, steel and power production.

"We all want single-window mechanism. We are working on that front. But it cannot happen overnight as rules for different departments are different," Steel and Mines Minister Narendra Singh Tomar said following an inter-ministerial coordination meeting with Coal and Power Minister Piyush Goyal and Environment Minister Prakash Javadekar.
