CSE expects coal to be a dominant share till battery costs drop in India. So cleaning coal to avoid local pollution becomes undebatable objective. CSE is working with coal-based thermal power sector since 2011 to achieve this. CSE highlighted the poor performance and need for regulations in Feb 2015 through it publication 'Heat on Power'. This spurred wide debates amongst the stakeholders. In Dec 2015, environmental norms were announced for the sector. Prior to which, the sector had no limits for pollution control. Since, then CSE has been playing a watchdog to support effective implementation of the norms. CSE is actively monitoring and providing support to power stations and regulators to ensure implementation as per the deadline committed. FGD tenders and In-combustion NOx tenders has been awarded for about 15-20 GW till date (April, 2019).
