The carbon footprint of products(CFP)is calculated as the quantity of CO2-equivalent emissions of greenhouse gases(GHG)from the product’s entire life cycle(from raw material acquisition to disposal and recycling), and is displayed on the product. By visualizing emissions throughout the supply chain, the CFP system helps to identify where emissions can be efficiently reduced. Unified reduction measures beyond corporate boundaries may be taken for total optimization. In Japan, the government is promoting CFP as a concrete example of “visualizing CO2 emissions” of products and services. In fiscal 2008, the first year of CFP operation, our country developed the guidelines and the standards for CFP, identified the issues in designing the CFP system, and surveyed consumer acceptability. In the second year, fiscal 2009, under the CFP Pilot Program, it was commenced to certify the Product Category Rules(PCRs)of concrete products and services, and verify calculation results and label descriptions of CFP. As for the procedures of PCR review and CFP verification for ensuring reliability and objectivity of the CFP system, our country set up the PCR Committee in the Pilot Program and implements those procedures on a trial basis, ahead of ISO implementation. Here I will introduce the main issues covered in these processes.
