オーストラリアの広大な農場における温室効果ガス排出量を2つの計算ツールで分析。ネットゼロ達成のための植林や羊の頭数削減策は利益を20～99%減少させ、損失補填には250～320豪ドルの炭素価格が必要と示唆。
English
This study analyzes greenhouse gas emissions on broadacre farms in Western Victoria, Australia, using two carbon accounting tools. It finds that achieving net-zero through tree planting and stock reduction could reduce profitability by 20-99%, requiring a carbon price of AUD 250-320 to offset losses.

📄 Abstract（原文）
ABSTRACT The global transition toward net‐zero agriculture requires robust, location‐specific carbon accounting systems at the farm level. This study examines greenhouse gas (GHG) emissions on broadacre farms in Western Victoria, Australia, and a production and income analysis to evaluate the cost‐effectiveness of various mitigation options at the farm level. Two calculators, the Greenhouse Accounting Framework (GAF) and the Meat & Livestock Australia (MLA), were used to collect data from eight mixed farms, and two scenarios were developed. The average emissions per sheep from MLA and GAF were 0.28 tCO 2 ‐e and 0.27 tCO 2 ‐e, respectively, and the profit per sheep of eight farms varied from AUD 146 to AUD 185, and per cattle from AUD 819 to AUD 1250. In general, enteric fermentation contributed 38%–84%, and manure management contributed 2%–5% of Scope 1 emissions. For Scope 3 emissions, from synthetic fertilizer use were the highest contributors to total emissions (up to 53%). In contrast, Scope 2 emissions from energy use contributed less to the total emissions (0%–1%). This study provides two farm management practices, including whole farm tree plantation and sheep stock reduction to achieve carbon neutrality at the farm level. However, this resulted in 20%–99% decrease in profitability, depending on the farm type and operation. Achieving net zero requires a higher carbon price of around AUD 250 to AUD 320 to offset this income loss. The study highlights a combined assessment of greenhouse gas emissions and the associated economic costs and benefits of different farm management practices in underpinning the shift of farmers toward carbon neutrality.
