摘要

Environmental life cycle assessment (LCA) was developed as a tool for sustainable, decisionsupporting environmental management. Applying agricultural sector-LCA in order to achieve both internal(comparative) and external (efficiency enhancing) benefits is a priority. Since the life-cycle assessment ofproducts and processes attracts great interest, applying the method in agriculture is relevant. Our studyundertakes a comparative environmental life-cycle assessment (LCA) of local arable crop productiontechnologies used for the main cultivated plants: maize, sunflower, lucerne, cereals, and canola(environmental data in the territorial approach calculated on a 1 ha unit and in the quantitative approachcalculated on 1 t of produce). We prepared an environmental inventory of the arable crop productiontechnologies, constructed the life-cycle models, and executed the impact assessment. We also compiled anenvironmental ranking of technologies. In the impact interpretation, we compared the results with thevalues of short rotation energy plantations in each impact category. We analysed carbon footprints closely.The obtained results help better assess environmental impacts, climate risks, and climate change as theypertain to arable crop production technologies, which advances the selection of appropriate technologiesadjusted to environmental sensitivities.
