Agriculture, forestry and other land use are important components of a global strategy to limit climate change. Using the example of EU agriculture, this paper examines the potential contribution of technological (i.e. technical and management-based) greenhouse gas mitigation options to climate targets. The quantitative framework presented allows to analyze disparities between marginal abatement cost curves (MACCs) derived from two different commonly used approaches, and between aggregated and regional MACCs. Results highlight the importance of assessing mitigation of agricultural emissions from a multi-dimensional perspective, considering regional heterogeneity of biophysical and economic circumstances and comprising both carbon-dioxide (CO₂) and non-CO₂ emissions. Regarding the ranking of technologies in terms of mitigation potential and costs, the results underline the need to consider technologies in a combined manner, avoiding the simple aggregation of mitigation potentials by individual measures without taking their interactions into account. Focusing only on standalone MACCs can lead to an overestimation of the mitigation potential. Conversely, measures classified as relatively high cost in standalone and aggregated MACCs should not be discarded, as they can still be cost-effective in some regions. The analysis shows that there is no ‘one size fits all’ rule that could be followed for identifying technologies that should be implemented in all regions. From a policy perspective the results imply that farmers should be granted some flexibility to adopt a set of cost-effective mitigation options that best fits their circumstances.

农业、林业和其他土地利用是限制气候变化全球战略的重要组成部分。本文以欧盟农业为例，研究了技术（即基于技术和管理的）温室气体减缓方案对气候目标的潜在贡献。提出的定量框架允许分析源自两种不同常用方法的边际减排成本曲线 (MACC) 之间的差异，以及汇总和区域 MACC 之间的差异。结果强调了从多维角度评估农业排放减缓的重要性，考虑到生物物理和经济环境的区域异质性，包括二氧化碳 (CO ₂ ) 和非 CO ₂排放。关于缓解潜力和成本方面的技术排名，结果强调需要以综合方式考虑技术，避免通过单独的措施简单地汇总缓解潜力，而不考虑它们的相互作用。只关注独立的 MACC 可能会导致对缓解潜力的高估。相反，不应放弃在独立和汇总 MACC 中归类为相对较高成本的措施，因为它们在某些地区仍然具有成本效益。分析表明，在确定应在所有地区实施的技术时，没有可以遵循的“一刀切”规则。
