ブラジル・ミナスジェライス州の商業コーヒー農場24軒を対象に、IPCCガイドライン（Scope1・2）に沿って農場レベルのGHG排出と、コーヒー樹・永久保存区域・法定保護区による炭素除去を2収穫期にわたり定量化した。多くの農場で除去量が排出量を上回り、窒素施肥が最大の排出源であった。多年生作物における排出・除去の双方を考慮した農場単位カーボン会計の有用性を示す。
English
This study quantified farm-level GHG emissions (IPCC Scopes 1 and 2) and carbon removals across 24 commercial coffee farms in Minas Gerais, Brazil, over two harvests. Removals exceeded on-farm emissions in most farms, with nitrogen fertilization the largest emission source. It demonstrates the value of farm-level carbon accounting that integrates both emissions and removals in perennial cropping systems.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では食品・飲料企業のScope3（カテゴリ1：購入商品）算定や、農産物サプライチェーンの脱炭素調達が課題となる。本論文は農場単位の排出・除去統合会計の実証例として、SSBJ開示やScope3算定における一次データ活用の参考になる。
In the global GX context
As ISSB/CSRD and Scope 3 (Category 1) disclosure push companies to account for agricultural supply-chain emissions, this farm-level study offers empirical evidence on integrating removals with emissions in perennial crops. It supports the growing demand for primary, farm-level carbon data in corporate value-chain accounting.

📄 Abstract（原文）
Coffee production is considered a potential contributor to climate change mitigation due to its perennial biomass and carbon storage capacity. However, empirical assessments of greenhouse gas (GHG) balances at the farm level remain limited for commercial coffee systems. This study quantified the carbon balance of 24 commercial coffee farms in Minas Gerais, Brazil, across two consecutive harvests (2020/21 and 2021/22). Farm‐level emissions of CO 2 , CH 4 , and N 2 O were estimated following IPCC guidelines (Scopes 1 and 2) using farm inventory data. Carbon removals were estimated using biomass increment coefficients for coffee plantations, Permanent Preservation Areas, and Legal Reserves. Estimated carbon removals exceeded on‐farm emissions in 16 (66.7%) and 19 (79.2%) of the evaluated farms in 2020/21 and 2021/22, respectively. Average carbon balances across farms were 104.5 Mg CO 2 e (0.59 Mg CO 2 e ha −1 ) in 2020/21 and 263.1 Mg CO 2 e (1.35 Mg CO 2 e ha −1 ) in 2021/22. Nitrogen fertilization represented the largest emission source, accounting for 66.7% and 54.2% of total emissions in each harvest. Higher productivity reduced emissions per unit of product but increased emissions per hectare due to greater input intensity. Coffee plantations accounted for 414.3 and 448.3 Mg CO 2 e of total removals in 2020/21 and 2021/22, respectively, corresponding to 70.9% of total removals across farms. These findings highlight the importance of considering both emissions and removals when evaluating the carbon balance of commercial coffee systems. Farm‐level carbon accounting provides useful information for understanding carbon dynamics in perennial cropping systems and supporting greenhouse gas assessments in coffee production. 2026 Society of Chemical Industry and John Wiley & Sons, Ltd.
