“…It has to be kept in mind that in our calculations nutrient uptake by crops as well as run-off or leaching losses during and particularly after the cultivation period were not considered. According to Blengini and Busto (2009), MartinezBlanco et al (2011) and Torrellas et al (2012 mineral fertilizer production shows relatively large impacts in the eutrophication category, but this cannot be confirmed in our study with our system boundaries.…”

In most of these studies, fertilizer production and the emission of N 2 O after fertilizer application show major impacts on the LCA results (see Brentrup et al, 2004a,b;Torrellas et al, 2012). Agriculture is accused of producing 10 to 12% of all greenhouses gases worldwide with approximately 38% of these emissions coming from organic or mineral fertilizers (IPCC, 2007;Smith et al, 2007).…”

“…Thus, the choice of ReCiPe (H) supplemented with USEtox allows us to conduct a broad assessment of the impacts under current and future climatic circumstances, instead of a selection of impact categories that are selected because these are considered important for agricultural LCA: acidification, climate change, eutrophication, photochemical oxidant formation and resource depletion (see for example Torellas et al, 2012), sometimes supplemented by toxicity impacts (see for example Nemecek et al, 2011). However, environmental impacts that occur as a consequence of agriculture, such as changes in soil quality and biodiversity (Meier et al, 2015), have not been included since no suitable LCIA methodologies capable of accounting for these impacts are available.…”

a b s t r a c tThe purpose of this work is to compare the environmental impacts of spring barley cultivation in Denmark under current (year 2010) and future (year 2050) climatic conditions. Therefore, a Life Cycle Assessment was carried out for the production of 1 kg of spring barley in Denmark, at farm gate. Both under 2010 and 2050 climatic conditions, four subscenarios were modelled, based on a combination of two soil types and two climates. Included in the assessment were seed production, soil preparation, fertilization, pesticide application, and harvest. When processes in the life cycle resulted in co-products, the resulting environmental impacts were allocated between the main product and their respective byproducts using economic allocation. Impact assessment was done using the ReCiPe (H) methodology, except for toxicity impacts, which were assessed using USEtox.The results show that the impacts for all impact categories, except human and freshwater eco-toxicity, are higher when the barley is produced under climatic circumstances representative for 2050. Comparison of the 2010 and 2050 climatic scenarios indicates that a predicted decrease in barley yields under the 2050 climatic conditions is the main driver for the increased impacts. This finding was confirmed by the sensitivity analysis. Because this study focused solely on the impacts of climate change, technological improvements and political measures to reduce impacts in the 2050 scenario are not taken into account. Options to mitigate the environmental impacts are discussed.

“…Electricity is one of the key inventories in a life cycle assessment (LCA); it is frequently used to describe the life cycle inventory (LCI) of various products (Mendoza et al 2012;Torrellas et al 2012;Treyer and Bauer 2016). The prevalence of the electricity inventory's use in LCA studies suggests that the accuracy of the inventory may significantly impact the result of an LCA.…”

Purpose The share of variable renewable energy sources (vRES) in the German electricity grid has increased over the past few decades. Due to the nature of the generation pattern of vRES, the increase of vRES causes the emission factor (EF) to fluctuate on an hourly basis. This fluctuation raises concerns about the accuracy of quantifying emissions with the current metric of the annual average EF as the respective EF may change depending on the time at which it is consumed. Methods The study calculated the hourly EF of Germany from 2011 to 2015 and investigated the effect of an increase of vRES on the EF. The calculated hourly EF was clustered based on three aspects of time: the period of time, the time of a day, and the day of the week. Results and discussion The study showed a higher proportion of vRES on weekend daytimes while the weekday nighttimes resulted in a lower share than the annual average. The study highlighted potential underestimation and overestimation of emissions by using annual average EF which ranged from +22% (2015 weekday nighttime of October) to −34% (2015 weekend daytime of May). Conclusions The study suggested that the application of hourly EF may be necessary to quantify the respective emission from the consumers that use electricity during the weekend daytime and weekend nighttime. For consumer use at other times, the emissions could be quantified appropriately by using the conventional annual average EF.
