They urged that these dams be removed from all the Nationally Determined Contributions targets pledged under the 2015 Paris Agreement that aims to combat global warming.

Environmentalists point to studies (here and here) conducted in the past decade that have shown that hydropower dams are major emitters of methane, a greenhouse gas 28 times-34 times more potent than carbon dioxide.
In 2019, India declared large hydropower plants as “renewable energy” resources – earlier, only projects smaller than 25 MW were deemed as renewable energy resources – thereby providing incentives to developers such as easier debt repayment terms and funding for associated infrastructure like roads and flood defences.
In August, the environment ministry also recommended restarting the construction of seven under construction hydropower plants in the Himalayan region that had been halted for various reasons.
