"India's plan makes clear there is a continued divide between developed and developing countries when it comes to making climate commitments," said Senator Jim Inhofe, chairman of the powerful Senate Environment and Public Works Committee.
Inhofe said that India is looking to countries such as the US to help cover the estimated USD2.5 trillion cost - required to implement its pledge to improve emissions intensity of its GDP by 33-35 per cent by 2030 - over the next 15 years.
In its INDC, India has also pledged to increase the share of non-fossil fuels-based electricity to 40 per cent by 2030 while agreeing to enhance its forest cover.
The INDCs - submitted by countries across the globe to the UN climate body UNFCCC - are meant to be the first step in a longer-term virtuous cycle of trust building, leading to ever higher pledges to combat climate change.
Senators still await the President's response, he said.
