- The GHG Protocol categorizes emissions into three broad scopes:
- Scope 1: All direct GHG emissions from sources owned or controlled by the reporting entity, including fossil fuels
- Scope 2: Indirect GHG emissions from the consumption of electricity, heat, etc., purchased by the reporting entity
- Scope 3: Other indirect GHG emissions from a variety of activities conducted by supply chains related to the reporting entity, ranging from the production of purchased materials to transportation/use of products and waste disposal.
Procurement of raw materials and parts
- Approximately 80% of paper is purchased for use in offices (including estimates for sites outside Japan). This percentage may change, as accuracy of data collection will be improved in the future.
- The products subject to accounting consist of copiers, printers, digital duplicators, facsimiles, digital cameras, electronic devices, embedded modules, thermal media, gas meters, toners, cartridges and peripheral equipment.
- GHG emissions coefficients used in the calculations are developed based on the LCA database published by JLCA and using Ricoh’s database.
- Regarding the amount of chemical substances handled, discharged and transferred, data on substances covered by the Japanese PRTR Act is collected from the Group’s sites inside and outside Japan.
- Tabulated environmental impact data obtained from individual sites is separately provided on our website.
Logistics and transportation
- Data for Japan covers transportation of cargo shipped by Ricoh or Ricoh Japan. For data outside Japan, international transportation is also subject to the calculations.
- For GHG emissions, electricity consumption from the use of copiers and printers is used for calculations.
- GHG emissions coefficients for electricity use (kg-CO2e/kWh) are developed using Ricoh’s database. The calculations are also based on the average emission factor for all energy sources issued by electricity utilities in fiscal 2000 (0.378) and reflect non-CO2 GHG emissions related to procurement of fuels and energy use.
Collection and recycling
- Data for office equipment and supplies are subject to collection and recycling accounting (excluding some areas outside Japan).
