The functional unit is adopted to express “carbon footprint, denoted as CFP” per emission per kilogram of melon. The system boundary of melon is classified into five stages, some of which is further divided, and finally eight processes, and LC-CO₂ is calculated as the total amount of CO₂eq emitted from each process. This estimated result compares with those of growing in warming greenhouse by fossil fuel in Kumamoto Prefecture, and discusses the cause of the difference between them. In addition, the effects of changing the transportation method and distance on total LC-CO₂ are considered from the viewpoint of the reduction of environmental burden.\n The estimated result of LC-CO₂ of melon produced in Choshi area was 650.2 g-CO₂eq/ kg.\nFollowings are the results obtained for the five lifecycle stages: the raw materials procurement stage: 410.6 g-CO₂eq (component ratio: 63.2%), the production stage: 145.0 g-CO₂eq (22.3%), the distribution and selling stage: 65.1 g-CO₂eq (10.0%), the operation and maintenance stage: 2.8g-CO₂eq (0.4%), and the disposal and recycling stage: 26.7 g-CO₂eq (4.1%). Most of the CO₂ is emitted from the facility building process in the raw materials procurement stage, especially from the multi-year used material,e.g. house pile and plastic sheet, which accounts for 37.3 % of the total melon LC-CO₂.\n Comparing the LC-CO₂ of melon growing in non-warming greenhouse in Choshi area to that of warming greenhouse in Kumamoto Prefecture, the later accounts for almost 8 times over for the burning fossil fuel. Therefore, it is clear that the non-warming production system in Choshi area is environmentally - friendly agricultural systems. In addition, it is clear that the over 600km transportation, truck transport accounts for only 10 % over than rail transport of the total melon LC-CO₂. Thus the change of transportation method should not widely contribute the reduction of environmental burden.","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"千葉科学大学"}]},"item_10002_relation_12":{"attribute_name":"論文ID(NAID)","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"40020058244","subitem_relation_type_select":"NAID"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA1230240X","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1882-3505","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"安藤, 生大"},{"creatorName":"アンドウ, タカオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"635","nameIdentifierScheme":"WEKO"},{"nameIdentifier":" 9000005339737","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/ 9000005339737"}]},{"creatorNames":[{"creatorName":"ANDO, Takao","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"33","nameIdentifierScheme":"WEKO"},{"nameIdentifier":" 9000005339737","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/ 9000005339737"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2014-07-17"}],"displaytype":"detail","filename":"k07-ronbun01.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","license_note":"copyright (c) 2013 by Chiba Institute of Science ","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"k07-ronbun01.pdf","url":"https://cis.repo.nii.ac.jp/record/133/files/k07-ronbun01.pdf"},"version_id":"3b7dbdb5-a92d-4895-8f03-14a81c77772e"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"千葉県銚子産メロンのライフサイクルCO₂の試算(その2)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"千葉県銚子産メロンのライフサイクルCO₂の試算(その2)"},{"subitem_title":"Estimating of the Life Cycle CO₂ of Melon Produced in Choshi Area, Chiba Prefecture, vol.2","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"15","path":["16"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-07-17"},"publish_date":"2014-07-17","publish_status":"0","recid":"133","relation_version_is_last":true,"title":["千葉県銚子産メロンのライフサイクルCO₂の試算(その2)"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-06-19T07:56:36.404211+00:00"}
