During the recent Lima World Bank/IMF meetings, India had raised the issue of a roadmap for USD 100 billion a year climate change financing by 2020.
Das has stated that India had also raised questions on the "correctness" of the recent OECD report, which has claimed that significant progress had already been made.
He expressed his views in his foreword to a discussion paper titled 'Climate Change Finance, Analysis of a Recent OECD Report: Some Credible Facts Needed' prepared by the Climate Change Finance Unit, Department of Economic Affairs.
The discussion and the review paper suggests that much more work has to be done, it said.

The OECD in partnership with Climate Policy Initiative (OECD-CPI) recently released a paper 'Climate Finance in 2013-14 and the USD 100 billion goal'.
The discussion paper examined "carefully the OECD report's accuracy, methodology and verifiability of the numbers reported. It finds serious problems on all counts".
Numbers were derived on self-reported basis from self-interested players, and open to "gaming" and exaggeration.
The discussion paper added that the views and analysis contained do not necessarily reflect the views of the government of India.
