2026年完全稼働予定のCBAMは、EU排出量取引制度の無償割当廃止と組み合わせて肥料価格を倍増させる。これによりEU内の鉱物窒素肥料使用が22%減少し、家畜糞尿で一部代替される。EU農業所得は7.7%減少するが、EU農業温室効果ガス排出は2200万トンCO2相当削減され、全世界での増加は見込まれない。
English
The Carbon Border Adjustment Mechanism (CBAM), set to be fully operational in 2026, combined with phasing out free allowances in the EU ETS, is projected to double mineral nitrogen fertilizer prices. This leads to a 22% reduction in EU fertilizer use, partially replaced by manure. EU agricultural income falls by 7.7%, but EU agricultural emissions decrease by 22 Mt CO2-eq with no significant global increase.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は炭素国境調整の導入を検討中であり、本論文はCBAMが農業・肥料部門に与える影響を定量的に示している。日本の農業保護政策や肥料価格への影響を考慮する上で参考になる。
In the global GX context
As CBAM is a cornerstone of EU climate policy under Fit for 55, this paper provides crucial empirical evidence on its sectoral impacts beyond heavy industry, highlighting regional disparities in agriculture and the need for tailored support measures.
👥 読者別の含意
🔬研究者:Provides a quantitative assessment of CBAM's cascading effects on agriculture using linked economic models, valuable for carbon pricing impact research.
🏢実務担当者:Demonstrates expected fertilizer price hikes and demand shifts, useful for agricultural sector adaptation planning and cost management.
🏛政策担当者:Shows that border adjustment can reduce emissions without increasing global leakage, but regional income losses require compensatory policies.
📄 Abstract（原文）
The Carbon Border Adjustment Mechanism (CBAM), scheduled to become fully operational in 2026, is designed to complement the EU Emissions Trading System (ETS) by replacing free emission allowances and preventing carbon leakage to non‐EU regions. CBAM initially covers energy‐intensive sectors, including mineral nitrogen (N) fertiliser production. Although mineral N fertiliser production is already included in the EU ETS, it is currently exempt from carbon charges owing to full compensation through free allowances. The phase‐out of these allowances and the introduction of CBAM are expected to increase the prices of both imported and domestically produced fertilisers, indirectly affecting the EU agricultural sector. This study quantitatively assesses the impacts of the expected fertiliser price changes on the EU agricultural sector and related environmental outcomes using the Modular Applied GeNeral Equilibrium Tool (MAGNET) and the Common Agricultural Policy Regionalised Impact (CAPRI) model. The results indicate that the combined effect of phasing out free allowances and implementing CBAM will double mineral N fertiliser prices. Higher prices are projected to reduce demand, leading to a 21.4% decline in domestic production and a 37% reduction in imports. Overall mineral N fertiliser use in the EU is expected to decrease by 22%, partially replaced by manure. Consequently, EU agricultural factor income is projected to fall by 7.7%, primarily affecting high‐input regions. Meanwhile, non‐EU agricultural income is projected to rise slightly by 0.05%, driven by higher exports. EU agricultural greenhouse gas emissions are expected to decrease by 22 megatons of CO 2 ‐equivalent, with no significant increase globally.
