The book also contains an analysis of the environmental and economic impacts of changes in resource circulation in East Asia. Although motorization is advancing rapidly, the vein industry for recycling used cars has not progressed. The authors estimate the amount of materials from used cars including new energy vehicles (electric and fuel cell vehicles) and propose desirable policies for used vehicles. East Asia is interdependent with respect to carbon and waste as well as the economy. China has regulated the import of waste recently and has started recycling its own wastes, putting pressure on neigboring countries to recycle their waste domestically. The authors estimate the environmental and economic impacts of such policy changes.
