Carbon Footprint Reduction

The aim of this study is to evaluate the efficiency of spring barley cultivation to indicate the reasons for its inefficiency and assess the possibility of the carbon footprint reduction potential. Survey data from 113 farms cultivating spring barley in 2016 were used. DEA (Data Envelopment Analysis) input oriented models were applied to assess technical, pure technical and scale efficiency. The carbon footprint of crop cultivation and its reduction potential for inefficient farms were estimated. The Fractional Regression Model (FRM) was used to explain how farm specific variables (structural and environmental factors) influence the efficiency of spring barley cultivation. Results indicate that the improvement of spring barley cultivation technology, through the effective use of inputs, especially mineral fertilizers, could lead to a reduction in the carbon footprint of its cultivation by an average of 32%, which, in turn, leads to a reduction in greenhouse gas emissions by 744 kg CO2e per ha. The economic size of farms, farm area, soil quality and annual rainfall significantly affect the results of technical efficiency.

This paper discusses the topical issue which examines the development of CO2 emissions in individual countries of the European Union (EU28) for the period between 2000 and 2017. Carbon footprint is monitored in four basic economic sectors of the EU28 countries—energy, other industries, agriculture, and waste management. The purpose of this paper is to conduct a structural analysis of the percentage contribution of individual sectors while determining the average conversion of emissions in tonnes per capita for individual countries, subsequently identifying the tendencies in the development of the detected rates. A cluster analysis for the EU28 that demonstrate similar carbon footprint values in the examined economic areas is conducted for the findings. The partial aim of the paper is to perform a comparison of the monitored countries and detect whether the differences between those striving for decarbonisation are diminishing. The energy industry is the most significant contributor to emission levels. The index analysis indicates that the level of emissions throughout the EU28 in all the monitored sectors has decreased, predominantly in waste management (by 40%,) which is followed by industry (17%), energy (by 16.2%), and agriculture (by 5%). The cluster analysis conducted for 2000 and 2017 has confirmed the convergence of the identified groups of the EU28. Individual clusters of the countries thus display minor differences and converge in general.

A Site

While waste marks the beginning of relocation, re-materialization, and resourcing processes, it is also a set of connections, producing specific figurations of citizenship that follow from, as they inform, waste management strategies. This article regards household practices to do with the disposal of used fats as a site where citizenship forms. The authors see the figure of ‘good citizen’ appear along the trajectory of kitchen fats. They contrast this figure with the ‘re-user,’ who acts by a different set of rules, so as to explore logics and normativities embedded in the mundane processes of discarding fats. Fat waste not only turns out to be different things for different stakeholders; it is in different fat disposal practices that different (kinds of) stakeholders emerge. As the authors situate citizenship in mundane practices, kitchen fats suggest the situational, material-relational character of waste and waste-eliminating schemes – and of citizenship itself.

Thermal power plants are of great environmental importance in terms of the huge amounts of wastes that they produce. Although there are process-wise differences among these energy production systems, they all depend on the logic of burning out a fuel and obtaining thermal energy to rotate the turbines. Depending on the process modification and the type of fuel burned, the wastes produced in each step of the overall process may change. In this study, the most expected process and non-process wastes stemming from different power generation processes have been identified and given their European Waste Codes. Giving priority to the waste minimization options for the most problematic wastes from thermal power plants, waste management strategies have been defined. In addition, by using the data collected from site visits, from the literature and provided by the Turkish Republic Ministry of Environment and Urbanization, waste generation factor ranges expressed in terms of kilogram of waste per energy produced annually (kg/MWh) have been estimated. As a result, the highest generation was found to be in fly ash (24–63 for imported coal, 200–270 for native coal), bottom ash (1.3–6 for imported coal, 42–87 for native coal) and the desulfurization wastes (7.3–32) produced in coal combustion power plants. The estimated waste generation factors carry an important role in that they aid the authorities to monitor the production wastes declared by the industries.
