Agenda1. Improving printed products to be “Eco-conscious” by quantitative
method, not by qualitative method• Definition of Eco-conscious products• Case study of plastic document file for Eco Product 2012• New idea to promote printed products
2. Reforming current calculation standard (Product Category Rule) to be wide-spread for SMEs
• Promotion of new calculation standard for printing• Accuracy of existing calculation standard for printing• Magnitude of calculation accuracy for new/existing standards
3. Utilizing “Printing Goes Green CLOUD (PGG-CLOUD)” to quantify environmental impact by the scale of CO2
• Primary data and secondary data collection• Actual operation• Next step to evaluate by different impact categories

Definition of Eco-conscious printed products:The printed products which have “shining- star quality” in terms of environment related issues backed by quantitative assessment (not by touchy-feely opinion, but by numerical numbers)

I. Calculation method is standardized to “cumulative”
II. Modeling for thickness of ink/varnish
III. Electricity usage = Rated output × fixed loading factor
IV. Loading percentage of truck is fixed at 50%
V. Calculate incineration by coated layer of paper only
VI. Printed products only by waterless printing method
VII.Avoid “scenario setting” of key items

*New PCR for “Printed products for waterless printing” was certified in Sep. 2012*Cost of CFP logo on PR tool for Eco Product 2012 should be minimized *Calculation results should be in +-5% range to utilize averaged figure*Carbon calculation by 7-printer, then categorized into 3 groups based on the results*Applying for CFP by group is effective to reduce application fee for SMEs

SummaryUtilization of quantitative assessment for “Eco-conscious Products”
a. Find “Hotspot(s)” to improve manufacturing process and/or select eco-friendly material
b. Communicate with print-buyers (consumers) by showing comprehensive internal comparison
c. Conduct many pilot projects to know efficiency of CFP (environment impact assessment)

Utilized for sales growth and cost-cut, not for academic experts to be satisfied
Simplification of calculation is extremely important to save time and money, “Detailed calculation cannot guarantee accuracy!”
