The delegation, led by BJP leader Rajiv Pratap Rudy, met Manmohan Singh in the Parliament House.
"Prime Minister has assured us that he is personally taking interest in the implementation of the National Action Plan on Climate Change, so that its various targets, including an increase in the share of new and renewable energy to 15 percent by 2020, are completed successfully," said a statement by Climate Parliament.
Climate Parliament is a network of cross-party members of parliament, working to accelerate the transition to a low-carbon economy by promoting renewables.
"The prime minister agreed to the high importance of the development of green energy in the country, with broader political initiatives," it said.
The group emphasised the need to finalise higher cross-border electricity trade targets with neighbouring countries in south Asia based on renewable energy in view of the high potential of such trade and its strategic geo-political importance.
The delegation also demanded that the government take steps to encourage private sector investments in the enhancement of transmission infrastructure for renewable energy among others.
