    Abstract

    This paper presents a tailored version of PestLCI 2.0, the most advanced life cycle inventory model for quantification of organic pes-ticide emissions from arable land, customized to appropriately account for viticulture specificities affecting pesticides emissions from vineyards. PestLCI 2.0 customization is further supported by the calculation of USEtox™ freshwater ecotoxicity characterization factors for active ingredients relevant in viticulture. Case studies on two different vineyard management systems illustrate PestLCI 2.0 model ap-plication. The customization of the PestLCI 2.0 model includes addition of 29 active substances, 9 application techniques, interception by a dual canopy (vine /grass cover), new soil and climate databases and further account of multiple vinerow treatment. Four substances dominate the overall toxicity profiles. Comparing the results obtained with PestLCI 2.0 with existing static emission quantification approaches results reveals that PestLCI 2.0 yields considerable lower emission loads and consequently, lower toxicity im-pact burdens. The issue of accounting for inorganic substances is discussed.
