Top Gujarat government ex-bureaucrat known to be close to Prime Minister Narendra Modi, Maheswar Sahu, wants the state officialdom to tighten the state’s noose over corporate social responsibility (CSR) activities of industrial houses. In a recently released book, “Small but Meaningful: CSR in Practice”, Sahu, who retired as additional chief secretary, industries, in 2014, has said the state must introduce “economic disincentives for irresponsible corporate behaviour”, even as encouraging “socially responsible business practices.”
