スペイン・ナバラ州で、野菜副産物を含む飼料（VBP食）と従来飼料で肥育した去勢牛の炭素フットプリント（CF）を比較。VBP食の肉は従来食に比べCFが約64%低く（42.01 vs 117.84 kg CO2e/kg肉）、地域の農業副産物の利用がGHG削減と循環経済に有効であることを示した。
English
This study compares the carbon footprint (CF) of yearling bulls finished on a diet including vegetable by-products (VBP) versus a conventional diet in Navarra, Spain. The VBP diet resulted in a significantly lower CF (42.01 vs 117.84 kg CO2e per kg meat), demonstrating that using local agri-food by-products reduces GHG emissions and supports circular economy principles.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では食品ロス削減や循環経済の推進が課題となっており、地域の農業副産物を飼料化する取り組みは、畜産のGHG排出削減と資源循環の両面で参考になる。また、Scope 3排出量の算定において、飼料由来の排出削減はサプライチェーン全体の脱炭素化に寄与する。
In the global GX context
Globally, this research provides empirical evidence on how circular economy practices in livestock feed can reduce GHG emissions, aligning with Scope 3 accounting and sustainable supply chain initiatives. It offers a practical example for the agri-food sector to lower its carbon footprint while addressing waste management.

📄 Abstract（原文）
Livestock farming is blamed for its significant carbon footprint (CF), contributing to environmental pollution and climate change. Among other approaches, this has highlighted the need to find alternative feeding systems for cattle production that are potentially able to reduce greenhouse gas (GHG) emissions. In this context, the objective of the present study was to compare the CF of producing cattle fed a Conventional diet versus cattle fed a diet that included vegetable by-products (VBP diet) sourced from the local agri-food industry. In this study, twenty-four entire male young bulls were reared in Navarra, Spain. Twelve calves were finished on the VBP diet that also included fodder and grain, and the remaining animals were finished with a local Conventional diet based on concentrate and straw. Results showed a larger CF of meat from animals fed the Conventional diet in comparison with the VBP-fed ones, that is, 117.84 kg versus 42.01 kg of CO2 equivalent per kilogram of meat, respectively. This research demonstrates that using by-products from the local agri-food industry for feeding cattle has an important beneficial effect on the environment. It is not only a circular economy solution that recovers and recycles by-products instead of treating them as waste, but can also notably reduce the GHG associated with livestock production. This study marks the beginning of ongoing research into the effect of introducing regional vegetable by-products in the diet of livestock and their corresponding impacts on productivity and the environment, particularly in terms of GHG emissions per kilogram of feed consumed.
