コープさっぽろにおける食品カーボンフットプリントの店頭展示の取り組み

抄録

Objective. The objective of this paper is to describe a case study of carbon footprint of food in a supermarket. The supermarket conducted an activity of the carbon footprint of food with many food companies. We describe the activity that involves collecting data, calculating the carbon footprint of food, and exhibiting the results.
Results and Discussion. We started to study the carbon footprint of food in 2008. The carbon footprint of 16 food products were exhibited in supermarkets of CO-OP Sapporo in 2010. The results have been revised three times until 2012. The number of the exhibited food was 37 in 2012. We organized a system with food companies in Hokkaido to calculate the carbon footprint of food. We designed a data acquisition sheet for food companies who were not familiar to the carbon footprint. We collected data of food in the food companies with the data acquisition sheet. We calculated the carbon footprint based on the data acquisition sheet. The carbon footprint has been shown in supermarkets by using Point Of Purchase (POP) advertising. The POP advertising is easy for the supermarket to show the carbon footprint to consumers because the POP advertising is under their own responsibility. On the other hand, it is difficult for consumers to notice the carbon footprint. There are a lot of products, about 30,000 items, in a supermarket and the number of the carbon footprint was too small.
Conclusions. This paper described an approach to show the carbon footprint of food in supermarkets. We expected that the carbon footprint of food in supermarkets is a good method to appeal the global warming and the carbon footprint of products to consumers. We realized the system to collect and calculate the carbon footprint with the food companies. Our method in which we use POP advertising is one of the ways to show the carbon footprint in the own responsibility of the supermarket. Our approach has some good features to realize the carbon footprint, but revealed problems for consumers to recognize the carbon footprint in supermarkets.
