TOKYO, Mar 22, 2024 - (JCN Newswire) - Japan’s only international payment brand JCB Co., Ltd. (“JCB”) has issued a white paper on the carbon impact of individual transactions made using various payment methods in Japan. The carbon emissions were calculated by Your Arbor Inc. (“Arbor”).

The Sustainable Development Goals (SDGs) and climate action outlined by the international community are gaining momentum, and are being systematically implemented in Japan. Simultaneously, there is a substantial increase in interest at the individual consumer level. However, JCB acknowledges that further discussion is needed on how this can contribute to the SDGs and climate action.

Given this, JCB believes it is important to objectively and quantitatively demonstrate how cashless payments can contribute to achieving a better society for consumers and the associated ecosystem.

As a first step in this effort, JCB and Arbor have conducted joint research to calculate and analyze the carbon dioxide (CO2e) emissions associated with consumer payment activities.

Following the recommended guidelines for the Life Cycle Assessment (LCA)*1 methodology, this white paper uses a comprehensive life cycle model for each payment method, mapping out the stages from raw material extraction to disposal, while assigning energy consumption and emission factors to each stage. The stages of the payment methods have been divided into 3 subsystems: Production phase, Operation phase, and End-of-Life (EOL) phase.

An example of the calculated result is as follows:

The white paper also includes the data and calculation logic used to determine CO2 emissions by payment method. The calculations are based on the principles and framework of the international standards ISO 14040, 14044, and 14064 on the LCA evaluation method.
