Industry-Academia-Government Collaboration to Reduce Domestic Co2 Emissions


Mar 2, 2011

Under the leadership of APS Professor TSUKADA Shunso, APU has been involved in experimental projects in collaboration with Oita Prefecture, Kitsuki City, the Regional Environment Network NPO Trust, and members of the cellular phone industry. This pilot scheme aims to reduce Co2 emissions through the promotion of "eco-driving" and "eco-commuting" and the conversion of Co2 reductions achieved into carbon credits*.Through the use of cellular phones, the scheme aims to make possible the measurement of hitherto difficult to ascertain Co2 reductions achieved through eco-driving and thus convert the reductions into carbon credits. By providing a sustainable incentive to local participants, the scheme aims to popularize the concept further throughout the region.

In AY2009, a sampling test was held in cooperation with Kitsuki City and local residents to measure the effects of "eco-driving" and to develop a system to differentiate between modes of transport being used. Developing such a system initially proved challenging due to the lack of reliable data that could be gained from the limited cellular technology at that time. Success came in AY2010 with the arrival of I-Phone and Smart Phone technology making possible the development of a more precise transport mode differential system.

Based on this success, in AY2010 a plan was put together for the carbon credit stage of the project followed by a briefing with the Japanese Ministry of Economy, Trade and Industry, and the Ministry of the Environment in February, 2011. Based on feedback from both Ministries and the collection of baseline data, the team will now move towards developing a sturdier emissions reduction project plan and further promoting the availability of user-friendly systems on all Smart Phones.

*Carbon Credits:
Co2 producers can receive carbon credits when they achieve a reduction in their Co2 emissions beyond a set target. With a market value, these credits can then be sold to Co2 producers who haven't met their emissions reduction target. With a value set by market demand, carbon credits can be sold on the open market or negotiated directly between business representatives.
