バイオ潤滑油（大豆油・菜種油）と鉱物油・合成油をLCAとカーボンフットプリントで比較したレビュー。バイオ油は生分解性とGWP低減に優れるが、農業生産段階に起因する酸性化・富栄養化など局所影響が大きい。菜種油はGWP最小だが影響カテゴリの多くで悪化し、大豆油は富栄養化と光化学スモッグを除き概ね最小。CFPではバイオ油が石油系より明確に優位と結論。
English
A review comparing bio-lubricants (soybean, rapeseed) with mineral and synthetic lubricants via LCA and carbon footprint. Bio-lubricants excel in biodegradability and GWP reduction but show higher local impacts (acidification, eutrophication) from agriculture. Rapeseed has the lowest GWP yet worst scores in several categories; soybean is lowest in most except eutrophication and photochemical smog. On CFP, bio-based lubricants clearly outperform petroleum-based ones.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
Scope 3 の調達排出や製品カーボンフットプリント算定に関わる基礎的知見を提供するが、SSBJ・有報開示や日本企業の実務に直接接続する内容ではない。化学・素材産業の調達排出把握の参考程度。
In the global GX context
Relevant to product-level carbon footprinting and Scope 3 upstream emissions for chemicals and manufacturing, but it is a review without direct linkage to TCFD/ISSB/CSRD disclosure requirements or transition finance.

🏢実務担当者:潤滑油調達におけるバイオ油採用の際、GWPだけでなく酸性化・富栄養化など局所影響も併せて評価すべき点を示す。
📄 Abstract（原文）
The global increasing awareness of sustainability has greatly affected the traditional lubricant market. The goals to reduce environmental pollution have increased the use of biolubricants rather petroleum based ones significantly due to several harmful impacts of the later including non-biodegradability, higher carbon emissions and bio-toxic wastes. In this review, a comparative analysis of biolubricants (soybean and rapeseed oils lubricants) with mineral and synthetic lubricants was performed with respect to their life cycle assessment (LCA) and carbon footprint (CFP) measurement. While bio-lubricants excel in biodegradability and global warming potential (GWP) reduction, they often have higher local impacts, especially in acidification potential (AP) and eutrophication potential (EP), due to the agricultural production phase. Although rapeseed lubricants imparted the lowest GWP, it showed a majority in the affected impact categories like acidification potential (AP), carcinogenics, respiratory effects (RE), eutrophication, ecotoxicity and photochemical smog (PS). Soybean oil based lubricants showed the lowest impact in most of the categories among the different types of lubricants, except for eutrophication potential and photochemical smog, for which mineral lubricants are the lowest. Considering the CFP, biobased lubricants are far more environmentally sound compared to mineral and synthetic lubricants. Their lower carbon emissions pave the way for a cleaner future, replacing the dependence on traditional petroleum-based lubricants.
