A CO2 reduction program “Green Point Club”, researched and developed by Waseda University and Japan Automobile Parts Recyclers Association (JAPRA), was announced in 2007 as a groundbreaking effort that has been developed to add a new “Environmental Contribution Index” to recycling parts. With the momentum of CO2 reduction such as abnormal temperature increasing, we promoted the use of recycled parts of vehicles will help to reduce the CO2 reduction effect. In this study, we summarize the CO2 reduction figures from using recycled parts in the past 10 years in Japan and verified it. We would like to the spread the method such as cooperation with the administration, information exchange with foreign countries, point return etc. and aim at further usage expansion.
