Climate Change Mitigation Policy Progression Indicator (CPPI)
– A Tool for Measuring Progression of Climate Change Mitigation at National Levels

National Institute for Environmental Studies (NIES) and collaborating institutions are planning to develop a set of indicators called Climate change mitigation Policy Progression Indicator (CPPI) to measure progression of climate change mitigation at national levels. This event gives a brief introduction of the research plan, and explains some initial calculations to examine countries’ progress in the mitigation of climate change.

1. Climate change mitigation Policy Progression Indicator (CPPI)
   – a tool for measuring progression of climate change mitigation at national levels: Introduction and initial examination

   Dr. Yasuko Kameyama, NIES, Japan

2. Remaining issues to be solved

   Dr. Kentaro Tamura, IGES

3. Comment from experiences in Environment Performance Index (EPI)

   Dr. Angel Hsu, Yale Univ.

4. Comment from perspectives from the South

   Dr. Hilton Trollip, University of Cape Town

5. Comment from experiences in IEA

   Dr. Timur Guel, IEA

Chair: Yukari Takamura (Nagoya Univ.)

A new indicator called CPPI (Climate change mitigation Policy Progression Indicator) was introduced by Kameyama. She also explained a trial examination using data of U.S., EU, Japan, and China, and indicated some important results. Next, Tamura made a brief remark on some of the ways to improve the indicator. After the two presentations, three experts were requested to make comments on the CPPI for further improvements. First, Hsu introduced some of the lessons learned in development of climate change indicators under EPI (Environment Performance Indicator). Next, Trollip made comments from perspective of the South, including situation in South Africa. Finally, Guel introduced some of the latest findings by IEA studies on energy-related indicators. The floor was opened for comments and questions. Two questions were raised. These comments will be reflected in the study to develop revised version of the indicators.

All the comments made today will be reflected in the revised version of CPPI before long. Then, data will be collected from the four countries / regions to try out the indicator. As other research institutions around the globe is also interested in researches related to indicators on climate policies, it may be worthwhile to consider organizing a workshop, participated by researchers who engage in such indicator development studies.
