When...the tinkle of corporate social responsibility (CSR) announcements is getting less and less audible amidst the growing economic gloom, British Telecom (BT) has come out with a sustainability index for Indian companies...which is a survey of 215 experts and 1,600-odd employees of top IT companies... The Global Sustainability Reporting Initiative and the other global initiatives bank on declaration by companies on their performance in various key areas. For instance, they must declare specifics about labour agitations, use of water and energy, and so on. It is for the world to go and find if the claims are true...Those who made it to the top 11 list are Tatas, Reliance, Infosys, ITC, Wipro, Suzlon, Airtel, Honda, ONGC, IL&FS and Satyam.
