Agricultural production and further processing to food and drink have large impacts on the environment. However, there are still few examples of LCA studies on beverages such as whisky. This paper presents a life cycle assessment of Swedish single malt whisky and different environmental improvements of the production chain are discussed. The functional unit is one bottle (70 cl) of whisky and results are obtained for global warming potential (GWP), Acidification Potential (AP), Eutrophication potential (EP) and primary energy (PE). The contribution to GWP is dominated by CO 2 emissions from transport of stillage. When avoided emissions from use of biogas are included, the net result is 2.1 tonnes CO 2 -eq. Acidification is mainly due to emissions of SO 2 from bottle production, transport and barley cultivation which ends up to 14.6 kg SO 2 -eq. Eutrophication results are totally dominated by barley cultivation, in total 8.6 kg PO 4 3 − . The total use of primary energy is 53.5 MJ/FU with a 50/50 distribution in renewable and non-renewable. Non-renewables emanate from fossil fuels used for transports and in glass production, whereas renewables are mostly used for heating in the distillery. Improvement analysis of transports included; (1) decreasing need of transport, (2) change of fuel and (3) change of transport mode. Decreasing transport of stillage is an efficient measure to reduce GWP and use of non-renewable energy. Substituting diesel with biodiesel for all road transports is an even more efficient measure for these categories, but increases other environmental impact. For all impact categories except use of renewable energy a scenario combining all improvements is the most efficient measure to reduce environmental impact. The results can be used by the manufacturer, but an improved and expanded LCA on product level can be used for a more specific eco-labelling of the different whisky editions. [ABSTRACT FROM AUTHOR]

This paper provides new understanding on how intermediary actors support the adoption of renewable electricity technology. While intermediaries complement each other in different phases of the process, there are also gaps and overlaps in the support that they provide. Results indicate that there is a great need of improving the communication among intermediaries and of a higher level of coordination among the tasks performed. Fostering the widespread adoption of renewable energy technologies is one of the most important drivers to limit the irreversible consequences of global warming that the world is facing today. However, the process of adopting such innovations is often complex and challenging. Previous studies have recognized the crucial role of intermediaries in facilitating the adoption process. Yet, little is known about how different intermediaries support the various adoption process phases, which intermediary type does what, and whether there are support gaps or overlaps among them. The authors of this paper contribute to previous research on innovation adoption and innovation intermediaries based upon research on the adoption context of renewable energy technologies in Sweden. They gathered secondary data and semi-structured interviews with nineteen intermediaries who support the adoption process of renewable energy technologies. The finding of this paper has implications on policy design, with regard, to how intermediaries can better perform in a technology diffusion context and to how intermediaries can be coordinated to provide better services during the different phases of the adoption process.

Tourism, and thereby hotels, play a crucial role in the European economy. The hotel sector features high energy consumption, which greatly contributes to the global warming effect. Thus, there is a need to investigate environmentally friendly technologies that have the potential to reduce energy usage within this sector. Information regarding the current status of the energy consumption in hotels is essential. Therefore, a study of 140 hotels in Norway and Sweden is presented in this paper to identify successful and sustainable measures to reduce energy consumption and related emissions. The energy use, available energy sources and thermal systems in the hotels are studied over a five-year period to identify consumption trends. The results reveal that 70% of the hotels have a mean annual energy consumption between 150 and 250 kWh/m2. A shift towards sustainable energy sources is observed in the hotels from 2015 to 2019, where application and overall consumption of district heating and cooling have increased, while electrical energy consumption has been reduced. District heating is the most prominent source of heating and is applied as the primary heat source in 70% of the hotels. The specific energy consumption for the group hotels that apply district heating is 218.9 kWh/m2/year, which is nearly 25% higher than the specific energy consumption of the 9% of hotels that apply heat pump solutions as a primary heat source. Thus, there is a potential to reduce the specific energy consumption in hotels. Two integrated transcritical carbon dioxide (CO 2) heat pumps were investigated as a sustainable measure to reduce energy consumption. The results reveal that a reduction of thermal energy consumption of approximately 60% can be achieved. • Energy analysis of 140 hotels in Norway and Sweden. • District heating and cooling in hotels increased by 18.0 and 10.9% from 2015 to 2019. • Hotels with heat pumps use 19.9% less kWh/m2 than hotels with district heating. • CO 2 heat pumps in hotels can reduce thermal energy consumption by about 60%.
