农业是欧盟温室气体排放的重要来源。通过使用欧洲农业的农场类型、面向供应方的线性规划模型，在欧盟-15的区域一级评估了甲烷和一氧化二氮排放的基线水平。对于一系列二氧化碳当量价格，我们评估了潜在的减排，以及由此产生的排放源在总减排中的最优组合。此外，我们还发现在给定碳价格下减排的空间变异性很大，这表明减排成本的异质性是减排政策设计的一个基本特征。与统一标准相比，以市场为基础的文书所允许的成本节约是巨大的。
Agriculture significantly contributes to emissions of greenhouse gases in the EU. By using a farm-type, supply-side oriented, linear-programming model of the European agriculture, the baseline levels of methane and nitrous oxide emissions are assessed at the regional level in the EU-15. For a range of CO2-equivalent prices, we assess the potential abatement, as well as the resulting optimal mix of emission sources in the total abatement. Furthermore, we show that the spatial variability of the abatement achieved at a given carbon price is large, indicating that abatement cost heterogeneity is a fundamental feature in the design of a mitigation policy. The cost savings permitted by market-based instruments relative to uniform standard are shown to be large.
