摘要:This paper addresses the assessment of greenhouse gas emissions from agriculture in theEuropean Union. We first estimate and compare net emissions from agricultural activities intwelve EU countries. These estimates are based on a set of farm-unit linear-programmingmodels. We then use these models to derive marginal and total abatement costs associated withdifferent levels of reduction targets (dual approach) and different values of carbon-equivalentemissions (primal approach). Finally, we explore the possibility of allowing afforestation on set-aside land. This paper highlights the discrepancies between countries regarding abatement costsand their sensitiveness to the accounting for carbon sequestration.
