Case Examples of Global Warming Impact Reductions in a Product's Life Cycle

Since the year 2000, Epson has engaged in Life Cycle Assessment (LCA) studies. LCA quantifies the environmental impact (global warming impact / CO2 equivalent: kg) that is generated in a product's life cycle, effectively and accurately exposes areas whose design should be improved, and reflects such elements into product improvement.


Reducing global warming impact with smaller and lighter inkjet printers

The Expression Premium XP-610, a "small-in-one" inkjet printer sold in North America, is 40% smaller than its predecessor, the Artisan 730, thanks to a smaller printer mechanism and a thin new print head and shorter ink cartridges. Equipped with an energy-efficient system-on-a-chip (SOC), this all-in-one consumes approximately 57% less power per day than its predecessor. These improvements mean that Epson has reduced global warming impacts of the Expression Premium XP-610 by approx. 31% across the product life cycle.

Reduction of global warming impact across the life cycle

Reduction of global warming impact across the life cycle

A life cycle assessment was used to calculate the global warming impact of the product at each phase of its assumed 3-year life cycle and express this as a CO2 equivalent. The life cycle includes material & product manufacturing, distribution, use by customer, and disposal/recycling of end-of-life products. Calculated assuming 5 A4-size color documents per day, per month (with 20 working days a month). 115V is used for calculation, based on the U.S specifications. The unit indicator by the Japan Ship Technology Research Association is used for calculating emissions during sea transport. Global warming impact will vary according to the customer's printer usage conditions. The reduction in CO2 emissions is expressed as a soccer ball equivalent, wherein 1 kg of CO2 is equivalent to the cubic volume of 100 soccer balls.

Reducing global warming impact with printers equipped with high-capacity ink tank systems

The Epson L-100 is an inkjet printer equipped with a high-capacity ink tank system that can be refilled by customers using large bottles of genuine ink.The L100 generates some 46% fewer CO2 emissions across the product life cycle than the Epson Stylus T13, a similar printer with replaceable ink cartridges, largely because ink is supplied by high-capacity bottles instead of cartridges.

A life-cycle assessment was used to calculate the global warming impact of the product at each phase of its assumed 3-year life cycle and express this as a CO2 equivalent. The life cycle includes material & product manufacturing, transport, use by customer, and disposal/recycling of end-of-life products. Calculated assuming 20 A4-size color documents per day, per month (with 20 working days a month). The reduction in CO2 emissions is expressed as a soccer ball equivalent, wherein 1 kg of CO2 is equivalent to the cubic volume of 100 soccer balls.

Reduction in CO2 across the life cycle of thermal receipt printers

The TM-T88V thermal receipt printer, released in 2010, consumes roughly 14% less total power than the outgoing TM-T88IV, resulting in approximately 10% less greenhouse gas emissions across its life cycle.

The evaluation conditions
The Life Cycle Assessment Method is used to calculate total global warming impact for the entire life cycle of a product (materials and product manufacturing, distribution, use by customers, and disposal and recycling after use) as CO2 emissions. 230V is used for calculation, based on European specifications. Usage of 300 receipts per day, with printer power on for 16 hours per day and off for 8 hours per day for 365 days per year over a period of 5 years is assumed. CO2 emissions will differ depending on customer printer use (e.g. number of prints, frequency of use, etc.)

Comparison of global warming impact across the life cycle of desktop PCs

The global warming impact across the life cycle of a desktop PC differs depending on the PC's features and performance. Epson reduced the power and resources consumed by the Endeavor ST160E by applying notebook PC technology to this desktop model. The global warming impact of the Endeavor NB51E was mitigated by narrowing its use to Internet and email applications, which allowed us to reduce the number of parts.

Effect of reducing the NB51E life cycle global warming impacts

These results are based on Eco Leaf environmental label evaluations. Displays are not included in the evaluations. Use is calculated as running or idling for 4.5 hours, in standby for 4.5 hours and powered off for 15 hours per day, 240 days per year for four years. The effects of the recycling of recovered end-of-life products were subtracted from the figures in the graph. Global warming impact may vary depending on customer use. Endeavor AT991E configuration: Intel Core i7 processor 3770 3.4 GHz, 8 GB RAM, 2 TB HDD, internal super multi-drive, and multi-card reader. Endeavor ST160E configuration: Intel Core i7 processor 3520M 2.9 GHz, 16 GB RAM, 500 GB HDD, internal super multi-drive. Endeavor NB51E configuration: AMD dual-core E2-1800 APU 1.7 GHz, 8 GM RAM, 500 GB HDD, no internal drive.
