日本語

ブラジル北東部ジョアンペソア都市圏5市の街路樹剪定残渣輸送を対象に、LCAで10年間のGHG排出を推計した研究。輸送が廃棄物管理で最大の影響段階であり、バイオディーゼルへの転換と局所再利用による輸送距離短縮の組み合わせで排出を46%削減できると示す。短期的・低コストの地域施策として2030年までの実施を提言する。

English

This LCA quantifies 10-year GHG emissions from transporting urban tree-pruning residues across five municipalities in Brazil's João Pessoa metro region. Transport dominates the waste chain; switching to biodiesel plus local reuse cutting travel distance yields a 46% emission reduction (to 475,754 tCO2e). The authors recommend this as a short-term, low-cost local action through 2030.

日本のGX文脈において

ブラジル地方自治体の廃棄物輸送LCA事例。日本の自治体廃棄物・バイオマス利活用やScope 3上流輸送排出の算定手法を考える際の参照例となるが、SSBJ・有報対応への直接の示唆は限定的。

In the global GX context

Adds a Global-South municipal case to transport-related Scope 3 and waste-sector accounting literature, relevant to CSRD/ISSB value-chain transport emission estimation and circular bio-waste reuse. Limited direct linkage to TCFD/ISSB disclosure frameworks.

📄 Abstract（原文）

This study assesses greenhouse gas (GHG) emissions associated with the transportation of biomass waste from urban tree pruning in five municipalities of the João Pessoa metropolitan region (Northeast Brazil): João Pessoa, Cabedelo, Santa Rita, Bayeux, and Conde. Transportation was identified as the most impactful stage in the waste management chain, and its reduction offers potential for reducing the carbon footprint. This study considers the current business-as-usual scenario, followed by the substitution of regular diesel fuel with S-10 diesel and biodiesel, and the reduction of travel distances due to local reuse of waste. To this end, the life cycle assessment methodology is applied to quantify GHG emissions throughout 10 years. The results indicate that the transportation of pruning residues in the five municipalities is responsible for the emission of 881,607 tCO 2 e, with the highest emissions in João Pessoa, followed by Cabedelo, Santa Rita, Bayeux, and Conde. Regarding travel distance reduction, total emissions could decrease to 673,622 tCO 2 e, representing a 24.6% reduction. The scenario involving the use of S-10 diesel showed a slight increase in the carbon footprint (total supply chain emissions), approximately 3.8% higher, resulting from the increased emissions generated by the operation of the hydrogenation unit. Using biodiesel would result in a 29% reduction in GHG emissions, lowering emissions to 622,310.66 tCO 2 e. Combining biodiesel with travel distance reduction would result in a 46% reduction, bringing total emissions down to 475,753.85 tCO 2 e, representing the most considerable reduction in GHG emissions. This is a short-term, low-cost local action recommended through 2030.
