Agriculture contributes a significant share of greenhouse gas emissions and in the future it will be faced with significant requirements to reduce greenhouse gases emissions. Model calculation of carbon footprint for products in the agricultural sector is based on the calculation of total greenhouse gases emissions resulting from the production; from the beginning of the production process to storage or submission, to the final consumer or to food industry. The calculation of the carbon footprint is based on the data about the used fertilizers and energy consumption in the whole processes of production. Energy consumption is determined for the work operations with tractor feeder machines (aggregate tractor and machine), which are intended for basic and additional tillage, seeding, fertilization, care, plant protection and others. The used amount of mineral diesel fuel consumption of tractors with various connection machines and self-propelled work machines were measured (e.g. harvesters or forage harvesters for maize). In addition, the energy consumption for harvesting and internal transport crops on the farm itself was included. The database of the footprint calculation model includes information (data) on the direct GHG emissions from used fertilizers (organic and mineral) and consumed fossil fuels, as well as indirect emissions from consumption of electricity and district heat. The sets of data in the database is defined for the average production in Slovenia. The analysis of the carbon footprint of agricultural products includes a production in conventional, integrated and organic farming for three different sizes of family farms. Two scenarios for soil tillage and seeding are considered in the model calculation of carbon footprint. The first scenario considers a conventional soil tillage with plough and seedbed preparation in secondary tillage with passive or active working elements on machines for seedbed preparation and seeding with conventional seeders, and the second scenario is direct seeding without secondary soil tillage.

COBISS.SI-ID: 28971815Energy efficiency measures and utilization of renewable energy sources have been consistently incorporated into energy strategic documents of the member states, addressing various sectors. Industry، being the backbone of the European economy, is still not sufficiently addressed, since its development is almost exclusively market driven. The importance of industrial sector for the economy is not questionable, nor its impact on the environment. More than a quarter of all final energy consumption in Europe can be attributed to industrial sector, representing one third of final energy consumption of natural gas and one third of electricity use, with more than three quarters of all final energy consumption of solid fuels. The paper presents an overview of the energy efficiency development trends in Slovenian industry. To assess the energy efficiency development, the Unit Consumption Index, has been applied to the Slovenian industrial sector, also highlighting some of the non-technical changes. The methodological part of this study is significantly complemented with the data, obtained from the extensive cooperation with the real industrial environment, bridging the gap between statistics, policies and practice.

COBISS.SI-ID: 28793127Influence of awareness rising activities and consumption feedback on energy behaviour and attitudes of specific end-users when they are not the bearers of energy consumption costs were examined. Students’ energy behaviour in university campus has been evaluated. Energy saving competition has been initiated between several dorms and consumption feedback system has been installed in six rooms. Individualized consumption analysis and feedback was performed and re-evaluated on monthly basis. Two specific responses were observed. Consumption feedback has initiated the constant change in students’ energy behaviour resulting in reduced energy consumption, whereas a negative response with no willingness to change was observed in second case. These two specific responses in behaviour patterns indicate the correlation between the initial attitude of end-user and provided consumption feedback. As students do not pay energy costs, they have no cost reduction motivation. Therefore it is most likely for good initial energy behaviour to further improve through consumption feedback.

COBISS.SI-ID: 28973607The programme group is participating in monitoring activities connected with radioactivity monitoring in the surrounding of the former uranium mine Žirovski vrh, operational monitoring of radioactivity in the surrounding of the Nuclear power plant Krško, measurements of radioactivity in gaseous effluents for Nuclear power plant Krško, independent supervision of the operational monitoring of the Nuclear power plant Krško, radioactivity monitoring in the living environment in the Republic of Slovenia, radioactivity monitoring of drinking water in the Republic of Slovenia and radioactivity monitoring of feedstuff in the Republic of Slovenia. With that it contributes importantly in ensuring radiological safety in the Republic of Slovenia, as well as in ensuring environmental acceptance of nuclear energetics.
F.30 Professional assessment of the situation
COBISS.SI-ID: 28961575We have shown that road geometry has a great impact on overall fuel consumption and emissions. Some roads connect traffic origins and destinations directly. On the other hand, some use winding, indirect routes. Indirect connections result in longer distances driven and increased fuel consumption. A similar effect is observed on congested roads and mountain roads with many changes in altitude. Therefore, we propose a framework to label road networks in a similar way as energy labels are provided for tires, vehicles themselves and electronic devices. This framework should take into consideration traffic volume, shares of vehicle classes, road geometry and energy needed for road operation and construction.
