Search Symbol (Half-width)	Description of Search Symbols
Space	"AND" indicates the intertwining of key terms used in a search
Double Quotation Marks ("") ( " " )	Double quotation marks indicate the beginning and end of a phrase, and the search will only include terms that appear in the same order of those within the quotations. Example: "image process" ： " image process "
?	Indicates a variable letter. Entering two ? will indicate two variable letters, and so on. Example: "Appl?", search results will yield apple, apply… e , appl y … ( (often used to English word searches) )
*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

In recent decades climate change has become one of the biggest long-term challenges of our society. Most organizations are thinking of possible solutions to reduce their GHG emissions as part of their commitment to a sustainable business. To achieve the purpose of the reduction of GHG emissions, the international community has been developed several types of flexible reduction mechanisms and management tools.
A product carbon footprint will cover the greenhouse gas emissions at each stage of the product’s life cycle. This may include extraction, production and transportation of raw materials, manufacture, distribution, end–use, and disposal/recycling. GHG emissions quantitative data of product carbon footprint can be calculated  based on the life cycle method. It helps enterprises to examine and find out the GHG reduction opportunities during the whole life cycle stages and facilitates the promotion of green purchasing among business and consumers.
The purpose of this study is to collect and analyze the information of environmental product declarations (EPDs) of the products that have published by Japanese Environment Management Association (JEMA). By statistical regression analysis methods, the carbon footprint, sulfur footprint, and energy footprint in the five product life cycle stages are explored and discussed on the base of product weight and unit of product weight as well as the correlation among the three footprints. The  effect of the GHG reduction of various products at the recovery stage is also examined.
The study results revealed that carbon footprint, sulfur footprint, energy footprint and product weight have a good linear and positive correlation among each other. The largest slopes of correlation lines between weight of product and carbon footprint were found to be at the product using stage of both electronic products, and then at  extraction and disposal /recycling stages.
At the recovery stage, the three footprints of products with recovering measures were larger than without recovering measures for most of the categories of products and the increment was found to be increasing with product weight. It indicates that the effectiveness of GHG reduction can be achieved by recovering actions. The categories BC and CF of products were found to be provided with larger GHG reduction than others. Interestingly, the sulfur footprint of few product categories with recovering measures were less than without recovering measures indicating that possible excess of SO2 emission could occurs at the recovering stage.
The findings and results found in this study can be as references for the product designers and police decision makers for the evaluation and assessment the environmental footprint of products.
