Environmental Performance
This section gives major environment data for corporate activities of the Daifuku Group.
Energy Conservation
CO2 emissions (Japan)
CO2 emissions (Non-Japan)

CO2 emissions associated with transportation
Scope 3
In order to reduce the greenhouse gases (CO2) emitted from all of our corporate activities, we are calculating the total CO2 emissions throughout our supply chain (Scope 3).
- Scope 1
- Greenhouse gases emitted directly from business activities (fossil fuels, etc.)
- Scope 2
- Greenhouse gases emitted indirectly from business activities (use of electric power and heat, etc.)
- Scope 3
- Greenhouse gases emitted indirectly from the supply chain of business activities (purchased products and service, use of products, etc.)
CO2 emissions throughout the entire supply chain (1,000 tons - CO2)
Scope 3 CO2 emissions (1,000 tons -CO2)
- Note:Due to rounding, the sum of individual items and the total may not always match completely.
CO2 Reduction Contribution
Daifuku strives to decrease its carbon footprint by providing eco-friendly products and services.
The contribution towards reduced CO2 from our products and services is calculated by taking the amount of CO2 released and subtracting it from the amount released during fiscal 2005, which acts as the base year.

Chemical Substances Management
Complying with PRTR Law
Paints and organic solvents are the primary chemical substances used by Daifuku in its production facilities. The Company manages and controls the usage amounts of special chemical substances on-site as designated under the PRTR Law.*
Glossary
- *PRTR (Pollutant Release and Transfer Register) Law: A law that requires enterprises to submit a report to their national governing authority specifying the number and volume of chemical substances they are releasing into the environment. This is aimed at voluntary management of chemical substances and the prevention of environmental pollution.

Air Pollution Prevention
Based on Ordinance 25, Clause 1 of the Ordinance Concerning the Reduction of Impact on the Air Environment of Shiga Prefecture, the Shiga Works is designated as a "place of business subject to a plan to reduce its environmental impact on the air." We are striving to control and reduce smoke-related air pollutants.
