Global warming is a serious problem. As a signatory to the 1997 Kyoto protocol, Japan agreed to a 6% reduction of CO_2 emissions relative to 1990 levels. Since then, Japan has strived to achieve this target, but the recent situation in Japan is far from satisfactory; in fact an increase of 8% is predicted. In order to keep its agreement, the Japanese government and many companies are continuing their hard work. In this paper, we focus on the logistics field. First, we report on and discuss the situation and some problems in Japan in this field relating to reducing environmental impact, especially CO_2 emissions. In order to further reduce the CO_2 emissions, we propose a construction of a new paradigm that considers both economic and environment aspects and one that is acceptable to consumers. For this purpose, it is crucial to show the environmental impact, such as CO_2 emissions clearly and accurately. For example, the "carbon foot print" system is currently promoted in Japan and globally. However, the database is inadequate and the calculation methods for CO_2 emissions are no longer relevant right now. Therefore, an appropriate measurement method to obtain accurate data for CO_2 emissions is essential. In addition, a fair allocation system is even more essential. If possible, it is more desirable to adopt a calculation system for CO_2 emissions same as to "Activity Based Costing system". In the logistics field, this problem is outstanding, the calculation and allocation of CO_2 caused by transport and/or delivery activities are made practically by the tonnage-kilometre (ton-km) method. In this paper, we focus on the logistics field. Logistics is a very important and basic field that relates to all companies, consumers and citizens in every society. As well as science and technology, a sociological approach should play an important part in reducing the environmental impact in this field First, we discuss the recent situation regarding environmental problems in logistics. Next, we arrange the efforts of the reduction of the environmental load by the government and companies. Thirdly, we propose a new paradigm for the logistics-consumption relationship. In order to actualize this paradigm, we then propose a new method for measuring CO_2 emissions by transportation and delivery activities and allocating them to each piece of cargo or owner of cargo. And by experiment, we show the validity of this system. Finally, we discuss directions in the near future and what the society should look like.
