The Japanese Fast-Start Finance Contribution

This research paper by the World Resources Institute assesses Japan's Fast-Start Finance (FSF) commitments between January 2010 and February 2012, analyzing the composition, transparency, and additionality of the funds provided to developing countries for climate change activities.

• Japan committed USD 15 billion to Fast-Start Finance (FSF), representing nearly half of the total FSF pledged by developed countries for the 2010-2012 period. By February 29, 2012, Japan had mobilized USD 13.2 billion since the September 2009 Hatoyama Initiative.
• Japan's FSF is primarily focused on mitigation, which accounts for approximately 70 percent of the funding. Mitigation efforts are largely funded through loans (about 75 percent) for infrastructure like urban transport. In contrast, the grant portion of the FSF is more balanced, with 30 percent for adaptation, 27 percent for mitigation and REDD+, and 43 percent for multiple objectives.
• Other official flows (OOF), including non-concessional loans, guarantees, and export and investment insurance, comprise roughly 40% of Japan's total FSF. Specifically, OOF totaled USD 5.1 billion of the USD 13.2 billion mobilized by February 2012, which includes USD 3.1 billion in leveraged private finance.
• The report questions whether Japan's FSF is truly "new and additional," noting that a significant portion reflects pre-existing pledges from the 2008 Japan Cool Earth Partnership and existing commitments to increase development finance to 0.7 percent of its GNI.
• Transparency in Japanese FSF reporting is limited due to disaggregated information and a lack of a centralized project list. While the study identified approximately 250 projects totaling USD 11.7 billion (nearly 90% of the mobilized amount), about 500 smaller projects could not be independently identified.
