“…Thus, this study only focusing on direct emission sources that occurs in the main business process of surface mining operation. GHG emission in coal mining operation generally occurs from fuel combustion, explosive, electricity, and fugitive emission from coal bearing strata [10]. The illustration of GHG emission in a typical surface mining shown in Figure 1.…”

Greenhouse gasses (GHG) are gases that could trap heat in the atmosphere and mainly made up of carbon dioxide (CO¬2¬) and methane (CH4). Coal is still one of the primary energy sources in several countries such as South Africa (71%), China (57%), Australia (30%), and Indonesia (44%). Therefore, coal mining operation is indicated as one of the biggest GHG contributor in the world. However, coal as commodity also indicated emitting GHG emission sequentially but its pathways are still debatable. GHG emission from coal mainly stated as an emission factor on both CO2 and CH4 because of coal combustion and/or existing gas in the coal bearing strata. The study of GHG emission or so-called Carbon Emission has been done based on several regions, coal rank, and condition. This study focuses on identify and projecting the GHG emission based on coal mining operation plan in North Kalimantan Province, Indonesia. This study aims to identify and adds more broader perspective about GHG emission from coal mining. The GHG emission estimation is based form Tier 1 IPCC Calculation method and estimated from a different scenario of production along the year. The GHG emission in this study estimated from fuel combustion and fugitive emission. The total emission estimated from this study was 1.31 × 10-02 kg CO2eq / kg coal.

“…In Poland, 67.9% of the generated electric energy is produced from coal (Figure 1), which results in high emissions of greenhouse gases [43].As a result of such a production structure, the price of electric energy in Poland is the highest in the European Union [44]. The energy policy of Poland to date has not fit in with the global trends favoring the transition to energy systems based on RESs [45].…”

Poland as the EU Leader in Terms of Photovoltaic Market Growth Dynamics—Behind the Scenes

The growing climate crisis forces the adoption of radical steps to neutralize our impact on the environment, despite the constantly growing demand for energy. Poland, which according to forecasts will not reach the EU target of 15% share of renewable energy sources by 2030, is nevertheless a leader in the EU in terms of the growth dynamics of the photovoltaic market. The aim of this article is to answer the question as to what caused such a huge interest in solar energy. In this article, the authors focus solely on residential installations. The dataset for the analysis was constructed on readily available national data on photovoltaics showing the key characteristics of the country and prosumers. According to this research, the prosumer’s profile shows that home photovoltaics are most interesting for the poorest households in rural municipalities, in regions with the highest unemployment rate, and among citizens of pre-retirement age. The decision to invest in photovoltaics is also influenced by the availability of subsidies and the price level of energy bills. On the other hand, no impact was found on insolation and environmental pollution. The results of the study will allow for a more conscious shaping of energy policy at the EU, national and regional levels.

“…Moreover, it is crucial to analyse the impact during the whole life cycle. The literature review (Guimara ˜es da Silva et al 2018) shows that there is a lack of modelling of the impact of mining processes based on the LCA methodology which also takes into account the quality of the fuel obtained. Even though Poland is one of the largest producers of coal in the EU, LCA and holistic assessment is still relatively rare (Burchart-Korol et al 2016;Kopacz et al 2017).…”

The life cycle phase of fossil fuel extraction is mainly considered in the life cycle assessment (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 processes 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.
