OKI DATA, from the second half of fiscal 2009 to the end of fiscal 2012, conducted the Carbon Zero Emissions Facilities Initiative to reduce overall CO2 emissions at all facilities that produce printers and multifunction printers by implementing reduction measures and utilizing carbon offsets for remaining emissions.
The initiative included the Fukushima Division, OKI Data Manufacturing (Thailand), and the printer section of OKI Electric Industry (Shenzhen) in China. OKI DATA conducted carbon offsetting for the three facilities by purchasing and cancelling emissions credits equivalent to CO2 emissions given off the previous fiscal year every half-year from the second half of fiscal 2009 to the end of fiscal 2012.
We promoted the initiatives by including the “Manufactured at a Carbon Zero Facility” logo on products, catalogs and other materials produced by the three facilities to broaden understanding of carbon offsetting and to serve as a model company to spur other carbon offsetting initiatives, independent reduction efforts by citizens, companies and other institutions, and concrete measures to address global warming.
CFC-115 used in temperature-controlled rooms at production facilities has been replaced by an alternative coolant as of September 1998, and use of halon-1301 in fire extinguishers has been eliminated as of 1999.
We work to rigorously ensure that hazardous substances are not used in production, starting with the substances identified by the RoHS directive.
Use of lead solder eliminated:
For the substrate assembly process at the Fukushima facility, we began using lead-free solder in 2006, and have reduced use of solder containing lead to zero as of 2015. Moreover, in terms of the quantity of lead-free solder used as well, we are reducing solder scrap through selection of materials, improvement of equipment and other measures.
Green purchasing and green procurement:
We actively purchase office supplies with the Eco Mark, and with cooperation of suppliers we promote green procurement that incorporates chemical substances management.
Paper use reduction and recycling:
We have worked to reduce the quantity of paper used in printer performance testing and other processes by improving test confirmation methods. In administrative divisions, we promote activities to reduce paper use, including duplex printing and use of backing paper. Also, we sort paper into high-quality paper, newsprint, magazine paper, confidential documents, cardboard and other categories for collection, and recycle it into toilet paper and other products.
Chemical substance information management system:
RoHS and other chemical substance data is obtained from suppliers and registered for management in the chemical substance information system “COSMOS” in accordance with the OKI Data Green Procurement Standard.
We’ve also developed the Global RoHS Navi System that connects all global production facilities and sales companies. Information on chemical substances contained specifically in products provided to facilities in each region is registered, and the system is operated so that management information can be confirmed by sales divisions.
Chemical substance analysis system:
Analysis equipment has been installed at each production facility so that components can be quickly analyzed for chemical substances, and we also work to continually enhance the list of substances that are measured.
In fiscal 2006 we reduced energy consumption by approximately 1,169 thousand kilowatts, or 23%, compared to fiscal 1996 through energy-saving measures for lights and office equipment, improving production facilities and developing more efficient work processes.
such sources, we reduced the amount, on a crude oil equivalent basis, in fiscal 2066 by 109 kiloliters, or 33%, compared to fiscal 1996. We intend to continue working to further reduce power and energy consumption.
