NEW DELHI: The environment ministry has thrown a spanner in the works of the commerce ministry's initiative to launch an online single window for making it easier to do business in India, a move that is reminiscent of its earlier solitary resistance to the National Investment Board.

An official familiar with the matter told ET that the ministry of environment and forests is not willing to comply with the concept of single-window clearance under the eBiz portal, which is designed to provide a platform to businesses to apply for licences from and pay the application fee to all ministries and departments concerned at one go.
