It reveals that developed countries together have so far earmarked almost $27.9 billion in “fast start” financing to help developing countries curb emissions and adapt to climate change over the next couple of years.

WRI, a Washington, D.C.-based think tank, says on its web site that while the pledges represent "a significant step in the right direction," donors "still have much to do in meeting their Copenhagen fast-start pledge."

All of this funding does not appear to meet the threshold of being “new and additional” financing, the benchmark that came from the summit.

“A number of pledges are restated or renamed commitments already made in the past. For example, Japan’s Hatoyama Initiative resembles the previously announced Japanese Cool Earth Partnership, with some new resources included in the Initiative,” WRI notes.

Japan tops the league of donors having pledged £15,000 million. Then comes the European Union with $9.7 million. The United States comes next with $3 million, the UK with $2.4 million and France and Germany with $1.6 million each. Bottom of the league amongst the 17 developed countries is Finland with $110 million.

The think tank’s online tool also tracks other aspects of the financing pledges, including the source of the funds and institutions through which the money will be channelled.

The Accord mandates that fast-start funds have a 'balanced allocation between adaptation and mitigation,' are 'new and additional,' are 'prioritized for the most vulnerable developing countries, such as the least developed countries, small island developing States and Africa,' and include 'investments through international institutions.'

In addition to meeting these criteria, next steps for developed countries include ensuring that their pledges are actually delivered.

"Though the commitments are clear, their delivery is uncertain. Some of the funds have yet to go through national budget appropriations processes," cautions WRI.

WRI has created this tool because is difficult to track and monitor fast-start finance pledges as there is no common reporting system. The present reporting systems of the multilateral development banks, under the UNFCCC and the OECD’s Development Assistance Committee, are decentralised and often not comprehensive.
