Environmental data -Calculation of the Ricoh Group’s Scope 3 Emissions-
Ricoh introduced the methodology known as Eco Balance in fiscal 1998 to clarify and effectively reduce the environmental impact caused by all its businesses. By using this method, we have been making lifecycle environmental impact evaluations.
Recently, in response to the increased need to clarify our environmental impact, a range of guidelines have been formulated*1. In reference to these guidelines, we have calculated our Greenhouse Gas emissions based on the Eco Balance concept and also calculated Greenhouse Gas emissions from the supply chain as our Scope 3 emissions.
These calculations have revealed that Scope 3 emissions account for 84.1% of total emissions.
The results also show that cat 1, 4 and 11 emissions are large among the Scope 3 categories. We will regard these categories as important and work to reduce emissions while also striving to improve the accuracy of our calculations. In fiscal 2012, in order to increase the credibility of calculation results, we received third-party verification from Bureau Veritas Japan of calculation results for cat 1, 4 and 11 emissions for imaging products. (For details, please click here.)
We will continue to clarify and disclose our Scope 3 emissions results and will work to reduce emissions in important categories.
- *1For example, the following major guidelines have been published:
Scope 3 Categories
|Ratio to Total Greenhouse Gas Emissions
|Cat1||Purchased Goods and Services||777＊1||25.1%|
|Cat3||Fuel- and Energy-Related Activities Not Included in Scope 1 or Scope 2||47||1.5%|
|Cat4||Upstream Transportation and Distribution||432＊2||14.0%|
|Cat5||Waste Generated in Operations||0.01||0.0%|
|Cat8||Upstream Leased Assets||87||2.8%|
|Cat9||Downstream Transportation and Distribution||0.1||0.0%|
|Cat10||Processing of Sold Products||13||0.4%|
|Cat11||Use of Sold Products||606＊3||19.6%|
|Cat12||End-of-Life Treatment of Sold Products||2||0.1%|
|Cat13||Downstream Leased Assets||228||7.4%|
|Total Greenhouse Gas emissions||3,091.1||100.0%|
- *1For Cat 1 emissions, we received third-party verification totaling 289,000 t-CO2.
- *2For Cat 4 emissions, we received third-party verification totaling 15,000 t-CO2.
- *3For Cat 11 emissions, we received third-party verification totaling 593,000 t-CO2.
Approach to Calculation and the Calculation Method
In reference to multiple guidelines, we have calculated the amount of emissions based on product life, operation hours, various per-unit emission indices, and emission factors set based on our own data. In the future, we will review the calculation method, emission factors, and boundaries to increase calculation accuracy.
Calculation method for each of the categories
|Cat1||Calculate by multiplying the total amount of purchased resources by the emission factor for each of the materials|
|Cat2||Calculate by multiplying the annual amount of capital investment by the emission factor|
|Cat3||Calculate by multiplying annual energy consumption by the emission factor|
|Cat4||Calculate for the transportation of cargo shipped by the Ricoh Group (excluding emissions included in Scope 1 and 2 totals)|
|Cat5||Calculate by multiplying the amount of waste sent to final disposal sites from the manufacturing facilities by the emission factor|
|Cat6||Calculate for the entire Group based on Ricoh Co., Ltd.’s data (for Japan) and on data from sales companies in Europe (for overseas)|
|Cat7||Calculate for the entire Group based on Ricoh Co., Ltd.’s data|
|Cat8||Calculate emissions from leased offices (excluding leased devices, automobiles, etc., since these are included in Scope 1 and 2 totals) based on the number of people
（Also excluding emissions from leased offices that are included in Scope 1 and 2 totals)
|Cat9||Calculate emissions from the transportation of products that are not shipped by the Ricoh Group|
|Cat10||Calculate by multiplying the amount of products that are not final products by the emission factor|
|Cat11||Calculate based on the assumed usage and life of the sold products|
|Cat12||Calculate based on the weight of the sold products and LCA data on emissions from the disposal of Ricoh products|
|Cat13||Calculate emissions from the use of assets leased by the Ricoh Group’s leasing company (Ricoh Leasing) based on the per-category quantity and emission factor. (Exclude emissions from leased Ricoh products that are included in cat 11 emissions and emissions from assets leased to the Ricoh Group that are included in Scope 1 and 2 totals)|
|Cat14||Not applicable (The Ricoh Group has no emissions from this category.)|
|Cat15||Calculate based on emissions from the companies of which Ricoh Co., Ltd. owns shares as well as based on the shareholding ratio|
