Giving top priority for clean environment, railways has decided to earmark one per cent of estimated cost of any project for environment works.
It has been decided for making specific provision towards environmental works in the estimate for all works in railways, said a senior official involved with the green initiatives undertaken by the public transporter.

It will be compulsory now to make provision for environment-related works as part of all rail projects, the official said.
As per the plan, railways will take measures for mitigation of air and water pollution during construction and operation and steps for natural air-conditioning of the building and geo-thermal cooling.
