ナイジェリア連邦教育省の2023年度教科書調達サイクルをISO 14040/14044に基づくゲートツーゲートELCAで評価。総炭素フットプリントは24,852 kgCO2eで、紙消費が59.9%を占め、入札公告・入札提出段階が主要ホットスポットと判明。デジタル調達や紙削減など政策介入の根拠を提供。
English
This study assesses the carbon footprint of Nigeria's Federal Ministry of Education textbook procurement cycle using a gate-to-gate ELCA following ISO 14040/14044. Total emissions were 24,852 kgCO2e, with paper consumption dominating (59.9%) and the tender advertisement stage as the main hotspot. It recommends digital procurement and reduced paper use to enhance sustainable public procurement.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では公共調達のグリーン化が進むが、途上国でのELCA適用事例は参考になる。SSBJやScope3対応で調達段階の排出算定が注目される中、本手法は日本の自治体や省庁の調達プロセス改善に示唆を与える。
In the global GX context
This paper contributes to global discourse on sustainable public procurement by providing empirical evidence from a developing country context. It demonstrates how ELCA can identify carbon hotspots in procurement processes, offering a replicable methodology for governments aiming to align with ISSB and CSRD disclosure requirements.

📄 Abstract（原文）
Public procurement is increasingly recognised as a strategic instrument for advancing environmental sustainability; however, limited empirical evidence exists on the environmental impacts of procurement operations in developing countries. This study assessed the carbon footprint and environmental hotspots associated with the FY2023 basic and secondary school textbook procurement cycle at the Federal Ministry of Education, Abuja, Nigeria, using a gate to-gate Environmental Life Cycle Assessment (ELCA) approach. The assessment followed the ISO 14040/14044 framework, covering procurement planning, tender advertisement and bid submission, bid evaluation, and contract award, while excluding upstream production and downstream use and disposal stages. Primary data were obtained through procurement records, structured inventory sheets, direct observation, and key informant interviews, while carbon emissions were estimated using the activity data–emission factor approach. The results revealed that the procurement cycle generated a total carbon footprint of 24,852.10 kgCO₂e. Paper consumption was the dominant emission source, contributing 14,875.25 kgCO₂e (59.9%), followed by fuel consumption with 6,882.60 kgCO₂e (27.7%), waste disposal with 2,581.65 kgCO₂e (10.4%), electricity consumption with 500.00 kgCO₂e (2.0%), and transportation with 12.60 kgCO₂e (0.1%). The tender advertisement and bid submission stage was identified as the principal environmental hotspot due to intensive documentation and administrative activities. The study concludes that integrating ELCA into public procurement can strengthen sustainable procurement practices by identifying carbon-intensive activities and informing evidence-based interventions, including digital procurement, reduced paper documentation, improved energy management, and environmentally responsive procurement policies within Nigeria's public sector.
