Environmental Conservation

Energy Conservation and Prevention of Global Warming

The Ricoh Group is rolling out environmental impact reduction activities covering the lifecycle of business processes, from procurement through recycling, with a view to reducing total lifecycle CO2 emissions by 30% by 2020 compared with the level in 2000. The stage of a product’s life where it has a particularly large impact on the environment is when the product is in use at the customer site. Given this reality, we develop products, especially core imaging equipment, with high energy-saving features, and we also provide services and solutions that help customers shrink their environmental footprint and support them in their efforts to reduce environmental impact.

RICOH MP C6003 won the Energy Conservation Center Chairman’s Award in the product and business model category at the 2013 Energy-Saving Awards in Japan.

The RICOH MP C6003/C5503/C4503/C3503/C3003 MFP series, released in June 2013, boasts fast recovery from sleep mode, largely thanks to Ricoh’s original energy-saving technologies—Color QSU (Quick Start-Up)*2 (DH fixing system) and a low melting point toner Color PxP-EQ. In addition, with the development of ASIC (application specific integrated circuits) that can operate under low electric power, these printers boast industry-leading*3 low energy consumption, under 0.6W, in sleep mode.
The RICOH MP C3503/C3003 delivers a huge improvement over previous models*4 with regard to sleep mode, drawing just 0.5W of power, down 58%, while connected to the network, and recovering in a mere 5.1 seconds, or 2.7 seconds faster. These models achieve incredibly high performance in terms of user-friendliness and energy conservation. Meanwhile, the RICOH MP C6003 exhibits high productivity—60 sheets per minute for color prints or black-and-white, while maintaining low power consumption of 0.6W, and easily clears even the tougher criteria of International ENERGY STAR Program Ver2.0, revised in January 2014.
Well-regarded for both user-friendly and energy-saving features, this series scored the Energy Conservation Center Chairman’s Award*5 in the product and business model category at the 2013 Energy-Saving Awards in Japan.

Environmental technology

Develops stand-alone power source, perfect for indoor lighting

The IoT (Internet of Things) society*6, linking various things around us with communication capabilities to networks, is coming. In this society, all sorts of things will acquire sensing capabilities, and stand-alone power source technology will become all the more important to facilitate communication even in places where power sources are difficult to maintain.
Ricoh successfully developed a complete solid-state dye-sensitized solar cell (DSSC) that delivers good power-generating performance even in weak indoor lighting from such sources as light-emitting diodes. Applying organic photoconductor technology accumulated in the development of imaging equipment and supercritical fluid technology, we created a DSSC
consisting only of solid state material, thereby over­coming issues with safety and durability that plagued previous candidates using liquid electrolytes. Our solar cell demonstrates more than twice the electric output of prevailing amorphous silicon solar cells, which are currently well-regarded for high performance. Going forward, we will promote further application of this DSSC as a stand-alone power source that should be able to contribute to a sustainable society.

Quantifying our “reduction contribution”

The Ricoh Group calculates the lighter environmental impact that society achieves through the use of Ricoh products and solutions as its “reduction contribution.” In fiscal 2014, the reduction contribution reached the equivalent of 395,000 tons of CO2, which surpasses aggregate CO2 emissions generated by the Ricoh Group’s manufacturing sites around the world. Going forward, we will continue to boost our reduction contribution, while steadily working to minimize the environmental burden caused by our own business activities, and thereby help to minimize the impact that society as a whole exerts on the environment.

Offering new approaches to work through fusion of paper and electronic documents

Within the Ricoh Group, we have developed ­various technologies, such as two-sided and intensive-­copying features as well as rewritable media ­applications, and offer products incorporating these technologies to our customers to reduce the environmental impact caused by paper use at offices and in meetings. We are presenting customers with the idea of paperless conferences as a new approach to work that fuses paper and electronic documents.
At the 67th annual meeting of the International Monetary Fund (IMF) and the World Bank Group, held in Tokyo in October 2012, and at the 8th APEC Transportation Ministerial Meeting, held in September 2013, Ricoh was tasked with installation and management of the document environment, combining new projection systems and visual communication products and applications to run meetings that cut way back on paper use. Over the three-day APEC meeting, paper usage was down by about 12,000 sheets, equivalent to 55kg of CO2 emissions.
We have also embraced the paperless method in-house, at management meetings, and cut paper usage by 120,600 sheets over the year in review, for a reduction effect equivalent to 553kg of CO2 emissions. We will continue to actively encourage our customers to follow our lead, because if more companies conduct paperless meetings, we will see a bigger decrease in environmental impact from business activities.

Scope 3 disclosure

We pinpoint the overall effect of our business activities as a corporate group on the environment and, seeking to successfully shrink our footprint, we began using the Eco Balance method in fiscal 1999 to evaluate product lifecycle environmental impact and disclose the results. In recent years, heightened social awareness of environmental issues has manifest a need to assess and disclose emissions across the entire supply chain, not just those generated through our own operations. This has become a component of how a company is perceived by society. Since fiscal 2013, we have undertaken Scope 3 disclosure, following the calculation standards of various major guidelines*7.
In fiscal 2014, Scope 3 emissions accounted for 84.1% of total greenhouse gas emissions associated with Ricoh Group business activities. Going forward, we will continue to pinpoint and disclose Scope 3 emission status and strive to reduce emissions in key categories.
Ricoh Lease, a member of the Ricoh Group, calculates its own Scope 3 emissions, and marked a first among non-manufacturing companies in Japan with full-category disclosure in September 2013. The results led to the discovery that emissions from products and services purchased through leasing contracts and from customer use of leased products are extremely high. Going forward, Ricoh Lease’s goal will be to bring these levels down, and in cooperation with vendors it will reinforce activities, especially efforts to encourage small and midsized corporate customers to select energy-saving products. This should lead to a reduction in CO2 emissions.
