India in its mind maybe winning the race of net zero, but the public-sector undertakings (PSU) of its energy sector would have a different take on the matter altogether. Moving to cleaner energy models is not supposed to be an overnight process and requires some heavy lifting, especially in case of a country that majorly relies on old infrastructure. And if the company does not upgrade the infrastructure, it invites scrutiny from investors on environmental, social and governance (ESG) grounds, which can potentially remove it out from the competition. Unfortunately, many PSUs in India today fear the possibility of this.
