The report which has been drafted jointly by Greenpeace and the Chennai based industry research firm Energy Alternative India (EAI), presents a detailed economic and environmental roadmap based on the Green Telecom Directive issued by Department of Telecommunication (DoT) based on the recommendation of the Telecom Regulatory Authority of India (TRAI) earlier this year. The report emphasizes that if the Green Telecom Directive is implemented effectively on ground, with mandatory compliance clauses within, it can help save the Indian telecom sector over Rs 2430 crore on its annual energy expenditure, apart from a saving of over INR 380 crore to the state exchequer.
