关于将农业纳入温室气体(GHG)减排工作(例如欧洲排放交易计划)存在广泛的争论。由于大多数农业温室气体排放来自面源,无法直接测量,因此必须通过计算方案(指标)得出。我们为奶牛场设计了五个这样的温室气体指标,并分析了它们的可行性、测量精度和诱导减排成本水平之间的权衡。诱导减排成本和计算精度的分析基于使用高度详细的单一农场优化模型的减排模拟。以定性方式讨论可行性。我们的结果表明,权衡取决于农场特征和目标减排水平。特别是,减排水平越高,详细指标的优势就会减弱。只有最不可行的指标才会导致减排成本,从而导致欧洲排放交易计划中给定价格的排放努力,尽管潜力相当小。因此,我们的结果表明,将乳制品生产纳入基于市场的减排政策的潜力不大。
There is broad debate about including agriculture in greenhouse gas (GHG) reduction efforts such as the European Emissions Trading Scheme. Since most agricultural GHG emissions originate from non‐point sources, they cannot be directly measured, and therefore have to be derived by calculation schemes (indicators). We designed five such GHG indicators for dairy farms and analyzed the trade‐offs between their feasibility, measurement accuracy, and level of induced abatement costs. Analyses of induced abatement costs and calculation accuracy are based on emission reduction simulations with a highly‐detailed single‐farm optimization model. Feasibility is discussed in a qualitative manner. Our results indicate that the trade‐offs depend on both farm characteristics and the targeted reduction level. In particular, the advantages of detailed indicators decrease for higher abatement levels. Only the least feasible indicator led to abatement costs that would result in emission efforts at given prices in the European Emissions Trading Scheme, although with a rather small potential. Our results thus suggest little potential for including dairy production into market‐based reduction policies.
