Since 1997, when the Kyoto Protocol was adopted, approaches to control global warming have been paid attention in Japan. And since the Paris Agreement was adopted, countermeasures against global warming have been globally required. At offices, choosing products with less emission of Greenhouse Gas (GHG) is optional at the time of purchases. Printers, consumables and paper used at offices are produced by various manufactures, which disclose in their own ways GHG emissions from their products. On the other hand, printers are used under different circumstances, which makes it difficult to understand the conditions during being used, while Eco-Leaf, a type-III environment label, calculates GHG emissions under product category rule (PCR). When printed paper is sold and provided to third parties, it is appropriate to disclose GHG emissions from the printed paper; however, it is necessary for printer users to calculate GHG emissions from printed paper based on emissions disclosed separately by printer companies and paper companies. This research quantifies GHG emissions per printed page based on how users handle printers. As the result, factors to control GHG emissions become clarified, which gives more opportunities to users for choices of printers.
