The report was presented at the UN Climate Convention Summit here yesterday by the UN Framework Convention on Climate Change's (UNFCCC) Standing Committee on Finance.
"Finance for climate action flowing globally stood at USD 650 billion annually in 2011-2012, and possibly higher," the report said.
Annual public and private flows from developed to developing countries ranged from USD 40 billion to USD 175 billion, it said.
Reacting to the UNFCCC report, India said the figure actually ranges from USD 340 billion to USD 650 billion, given gaps in data.

The range includes projects between developed countries, which would not benefit developing countries who are in need of the funds.
Ray said that even though the annual flow of funds between developed to developing countries ranged from USD 40 billion to USD 175 billion, it is misleading because "there is no agreed operational definition on climate finance multilaterally" and thus what kind of project funds can be counted in that range is up for debate.
She explained that "in many cases here, the climate is a co-benefit and entire investment is counted as climate finance".
Both of these descriptions fall outside of the UNFCCC and Green Climate Fund goals of having new and transformational funds available to India and other developing countries for climate-related projects.
