“…Several authors in different countries and universities have used LCA to conduct analyses of electricity matrices, such as Sengül et al [13]; Atilgan and Azapagic [14]; Berrill et al [15]; Garcia, Marques and Freire [16]; Lelek et al [9]; Asdrubali et al [17]; and Wolfram, Wiedmann and Diesendorf [18]. Different jurisdictions have addressed this issue, such as European countries, China, Australia, Canada, and Brazil.…”

“…Sengül et al [13] conducted a study on potential environmental impacts from the extraction of firewood for electricity generation in Turkey, which was assessed by means of LCA, based on data from 12 local mining sites. The authors used as Life Cycle Impact Assessment (LCIA) methods the CML (Center of Environmental Science of Leiden University), TRACI (Tool for the Reduction and Assessment of Chemical and Other Environmental Impacts) and ReCiPe; from that, it was possible to observe the local emissions and to quantify the environmental impacts.…”

The present paper aims to evaluate the past and future environmental performance of the electricity generation in Brazil in terms of Global Warming Potential (GWP) and Global Temperature Potential (GTP). To that end, the Life Cycle Assessment (LCA) tool was used to evaluate the system's environmental performance, based on ISO 14040 and ISO 14044, using the Ecoinvent v 3.3 database. This study provides data on global warming by the GWP and GTP 100 years impact category. The functional unit and reference flow is kWh. The model was applied to the electricity generation in Brazil for the years 2016-2026 using Umberto NXT Universal software. The results indicate that the greatest environmental impacts lie on generation sources such as oil, natural gas, hydropower and hard coal. Carbon dioxide was the main contributor to atmospheric emissions in the life cycle of the Brazilian electricity matrix in 2016 and 2026. The total potential impact (and per kWh) is expected to decrease until 2021. The Brazilian electricity matrix is expected to be less pollutant in terms of carbon footprint until 2021. The study can contribute to directing public policies, promoting development actions and encouraging different electricity matrices.

“…However, the need to remove large amounts of overburden to uncover the deposit contributes to a much greater degradation of the landscape. From the analyses of this area available in the literature, the work of Şengül H. et al regarding the LCA of opencast lignite mines based on high quality data from 12 mines in Turkey, including 9 opencast mines, should be quoted [23]. It is also noted in this work that the impacts related to the combustion phase in LCA of coal based production of electricity have so far been the subject of more LCA studies and are better documented.…”

The life cycle phase of fossil fuel extraction is mainly considered in the LCA when evaluating the energy production processes. It is then only one of many unit processes, which contribute to the blurring of mining-relevant results. There are few items in the literature focusing exclusively on the lignite mining phase and analysing the specific mining conditions and associated environmental impacts. The article focuses on the LCA of lignite mining pro-cesses on the basis of data coming from a Polish mine. The technology for opencast lignite mining is noted for its high production efficiency, high level of recovery and lower risk as regards the safety of workers when compared with underground mining systems. However, the need to remove large amounts of overburden to uncover the deposit contributes to a much greater degradation of the landscape. Analysing the results obtained, several key (hot spot) elements of the lignite mining operations were distinguished for modelling the environmental impact, i.e.: calorific value, the amount of electricity consumption, the manner in which waste and overburden are managed. As a result there is a high sensitivity of the final indicator to changes in these impacts.

“…These include, among other issues, problems with the selection of an appropriate functional unit, the boundaries of the system being analysed or the determination of appropriate impact categories reflecting significant environmental problems in the mining industry. In the LCA research on the surface mining of lignite based on high-quality data from 12 mines in Turkey, including nine open-pit mines [17] as well as a study of four South African mines [18], the author underlined the issue that the standard LCA impact categories, such as global warming, ozone depletion, toxicity for humans, ecotoxicity of water, acidification and eutrophication, are insufficient to describe the environmental impact of mineral resource extraction. Such categories as land take, water consumption, energy use and depletion of resources were proposed as the most significant, and equivalent to the LCA analysis of the mining sector [19].…”

This paper presents a model combining the LCA (Life Cycle Assessment) of fossil fuel extraction with its quality parameters and related CO2, SO2 and dust emissions at the stage of the combustion process. The model which was developed aims to identify the environmental impact of the processes of electricity production from selected energy carriers over their whole life cycle. The model takes into account the full LCA of fossil fuel extraction (of both hard and brown coal), its enrichment and fuel production as well as the environmental impact associated with emissions introduced into the air at the stage of electricity generation based on the fuels evaluated. Such an approach allows one to determine the fuel quality parameters that affect the environmental impact of energy production based on an LCA of mining and assigns the degree of environmental impact involved in particular production processes. Overall, the results obtained based on the proposed model permit the identification and prioritisation of the individual processes in the electricity generation life cycle which contribute the highest share in the general environmental impact indicator, having taken into account the modelling of the quality of the fuels used (calorific value, ash and sulphur content).
