Opis:
A method for the allocation of technologies of reduction of CO2 emission to sources of emissions based on dynamic programming has been described. The purpose of the application of the method was to develop an efficient strategy of allocating financial means for reducing CO2 emissions from a set of coal and lignite fired power plants (carbon dioxide sources) which enables reduction of the total emissions to the required level within a given time horizon, at the minimum cost. The application of the method is illustrated based on the set of the 20 largest Polish coal and lignite fired power plants.

Opis:
In the last two decades, there has been observed a noticeable increase in the popularity and availability of air transport services, including regional ones. This intensive development of transport is accompanied by an increase in the adverse impact to the environment, increases noise level, and exhausts emissions, despite the modification and modernization of engines. Determining the emission for regional flights takes into account the specificity of the aircrafts design, such as the size of the aircraft and the performance of the engines. In this article, an attempt was made to determine the CO2 emissions of a business jet flying from Gdansk to Rzeszow. The methodology of the research (the method of calculating emissions based on fuel consumption) and the performance characteristics of the aircraft engines have been described. In the first part of the article, the speed-altitude characteristics of the DGEN-380 engine for different cruise parameters were determined using the virtual engine test bench WESTT CS/B. These characteristics have enabled the engine to match the flight characteristics (altitude, speed). For specific flight parameters, the thrust and fuel consumption were determined. On this basis, for the adopted trajectory and flight time of an aircraft equipped with two DGEN-380 engines, total fuel consumption and CO2 emission factors and values in CRUISE phase was determined with regard to the wind speed and direction. The obtained results were illustrated graphically and discussed.

Opis:
An analysis of the methods used in Bulgaria for estimating CO2, SO2 and dust emissions has been conducted. The first methodology, which is officially used by all energy auditors at the Agency for Sustainable Energy Development targets the energy efficiency of combustion devices installed mainly at industrial enterprises. The second methodology, used by the Ministry of Environment and Water, is more comprehensive and can be applied to thermal power plants, small combustion plants as well as industrial systems. In recent years, many projects related to energy efficiency and renewable energy projects, including hydrogen technologies, which require an assessment of reduced greenhouse gas emissions, have been implemented as a priority. The use of reliable and accurate methods is essential in the assessment of greenhouse emissions. A novel methodology, based on stoichiometric equations of the combustion process for solid, liquid and gaseous fuels has been proposed and comprised. This novel methodology is characterized by higher precision compared to the methods currently in place and this is achieved through calculating emissions from the combustion of energy fuels accounting for the full elemental composition of the fuel and its heating value, whereas the current commonly applied methods use only the fuel type and the carbon content. A further benefit of the proposed methodology is the ability to estimate emissions of fuels for which there is no alternative method for calculating CO2, SO2 and dust. Results of emission calculations according to the analysed methods are presented. Finally, a comparative analysis between the presented methodologies including an assessment of their accuracy and universal applicability has been made.

The article presents the results of road tests of the passenger car. The aim of this study was to determine the effect of variations in the vehicle braking methods on the carbon dioxide emissions. Inhibited using the gear ratios increase – less gear and using motion resistance while driving a rundown, in addition to using the brake system in the final stages of journeys made. The use of engine braking by drivers as a result of the reduction gear, for example during transport to the intersection, traffic light, railroad crossing, in place of the drive by coasting is particularly emphasized by the promoters of eco-driving. It is raised the issue of avoiding unproductive, from the viewpoint of the work efficiency of the engine, the engine idle speed. The verification of environmental aspects of the use of engine braking was made because of the testing under real traffic conditions. Test drives were carried out at the measuring section, free from traffic. The test vehicle accelerates to a speed of 50 km/h, and then two ways of the speed deceleration were used. The values of the concentration of harmful carbon dioxide in the exhaust gases were achieved by using a mobile apparatus for testing exhaust emissions.

With the invention of specialized, portable research equipment, construction of which enabled road tests of vehicles, it has become possible to verify benefits ensuing from application of eco-driving rules outside the laboratory – the test stand measurements. Test of the vehicles’ operation in terms of ecology are essential especially in case of toxicity of exhaust gases in dynamic, transient conditions of engine operation. Despite the attempt to reflect those conditions in dynamic research tests, it is not possible for fully reconstruct real conditions of operation of vehicles of different homologation categories. Due to this fact in recent years, the biggest research potential in automotive industry has been focused right on the road tests of vehicles in real traffic conditions. The article presents the results of measurements of exhaust emissions of passenger car in real traffic conditions. The aim of this study was to initial verification how the driving style influences on the carbon dioxide emissions from vehicle engine and fuel consumption. The determinants were the measurements of the concentration of CO2 emitted to the atmosphere from the power unit of the tested vehicle. In the measurements, a portable exhaust emission analyser was used.

Opis:
The transport industry, and especially aviation and maritime transport, emits significant amounts of CO2, adversely affecting the environment. The Sustainable Development Goals not only indicate the need to reduce CO2 emissions, but also to provide access to information on the amount of emissions, on top of their environmental and financial impacts. The main source of this type of information is found in financial and non-financial statements prepared by entities of the transport sector. CO2 re-porting disclosures should be subject to the principle of true and fair view ensuring adequate materiality, transparency and comparability of information. The aim of the article is to assess the scope and method of reporting information on CO2 emissions in the financial and non-financial statements of selected groups of the air and maritime transport sector. By means of content analysis, disclosures on this subject were reviewed and compared against the applicable legal regulations in the field of CO2 emissions reporting for the industry. The results of the research indicate a significant differentiation in the methods of reporting, in particular relating to the valuation and presentation of CO2 emission allowances in reports on the financial position in air transport and the manner and scope of reporting non-financial information in maritime transport. The obtained results indicate insufficient comparability of the reported information and a need for harmonisation of the provisions of law regarding the scope and forms of reporting. The findings also indicate a need to combine financial and non-financial information in single reports in order to properly interpret the effects of emissions.

Opis:
The emission and absorption fluxes of CO2 and CH4 in the environment have been characterized. It has been pointed out that the anthropogenic emission of CO2 amounts only to 3% of emissions from the natural sources. It has been also noted that increasing CO2 absorption of terrestrial ecosystems by 3% could inhibit the increase of CO2 concentration in the atmosphere. This means that mitigation of global warming by intensifying natural processes is a more sustainable solution than performing expensive changes in energy policy. Lowering the emission of methane, on the other hand, can be accomplished by utilizing fodder additives for ruminants and the process of microbiological methane oxidation in covering soil layers or biofilters.
W artykule scharakteryzowano strumień emisji i absorpcji gazów cieplarnianych CO2 i CH4 w środowisku. Zwrócono uwagę, że antropogeniczna emisja CO2 wynosi zaledwie 3% poziomu emisji ze źródeł naturalnych. Ponadto zauważono, że intensyfikacja absorpcji CO2 przez ekosystemy lądowe o 3% mogłaby zahamować wzrost stężenia CO2 w atmosferze. Oznacza to, że bardziej zrównoważone jest przeciwdziałanie efektowi cieplarnianemu poprzez intensyfikację procesów naturalnych od kosztownych zmian w polityce energetycznej. Natomiast ograniczanie emisji innego gazu cieplarnianego – metanu – można osiągnąć poprzez stosowanie dodatków do paszy dla zwierząt przeżuwających oraz wykorzystanie procesu mikrobiologicznego utleniania metanu w nakładach glebowych i biofiltrach.

Opis:
Tightening the environmental norms that result from the priorities of the EU 2030 Energy and Climate Package and the reform of the EU ETS have caused the necessity to implement an effective system of managing the risk of carbon dioxide emission and integrate it with the existing enterprise management system. Evaluation of the direction and strength of correlation between EUA price changes and energy companies stock price returns is crucial from point of view the managerial staff making proper decisions about the use of the CO2 emission permits by energy companies. It is an important stage of carbon emission risk management process. The aim of this paper is to verify the possibility of use the multifactor models with GARCH structure as a tool supporting the carbon emission management process in energy companies. Empirical analysis is connected with the estimation of multifactor models with GARCH structure in the Phase II and Phase III of the EU ETS functioning for two groups of Polish energy companies: group of the Respect Index companies and others. Such an approach allows to check whether the Respect Index companies are more robust than others on the carbon emission risk, in particular the EUA price risk associated with the intensification works on modifying the EU ETS functioning. We found that the impact of EUA price changes on energy companies stock returns and their volatility is statistically insignificant in case of all Respect Index companies

Opis:
Power generation units, suitable for individual users and small scale applications, are mainly based on spark ignition engines. In recently performed research, reductions of emissions coming from such units, especially considering carbon dioxide emissions, are deemed as the issue of particular importance. One of solutions, postponed to reduce impact of spark ignition engine-based units on the natural environment, is transition from fossil fuels into renewable gaseous fuels, as products of organic digestion. Nonetheless, development of new solutions is required to prevent further carbon dioxide emissions. The paper presents a novel dual approach developed to reduce carbon dioxide emissions from stationary power units, basing on spark ignition engine. The discussed approach includes both reduction in carbon content in the fuel, which is realized by its enrichment with hydrogen produced using the solar energy-supported electrolysis process, as well as application of post-combustion carbon dioxide separation. Results of the performed analysis suggest profitability of transition from fossil into the hydrogen-enriched fuel mixture, with significant rise in operational parameters of the system following increase in the hydrogen content. Nevertheless, utilization of the carbon dioxide separation leads to vital soar in internal energy demand, causing vital loss in operational and economical parameters of the analyzed system.

Opis:
The main objective of this article was to make a quantitative and qualitative attempt to examine the relationship and the correlations between the development of transport and fuel efficiency of resource use. The analysis has shown that road transport has now gained a special status in people’s daily lives. The increased mobility of European citizens has caused cars to currently have the greatest share of the energy needs of road transport. This happened in despite improvements in the energy efficiency of these cars and freight transport growth. The projected continued growth of freight transport will contribute to the further changes in the structure of energy consumption by road transport. Despite the high growth rate of energy efficiency and improvement in trucks, the share of demand for fuel by these vehicles will increase the total fuel demand for the road transport sector. At the same time the energy consumption of cars will reduce their share in the total fuel needs of transport. The improvements of energy efficiency of passenger cars and trucks will not offset the increase in demand for energy in road transport. The above regularities create a key challenge facing the transport system – how to meet the constantly growing demand for energy? An important issue in achieving the objectives of sustainable transport is not only the development of technology, but also human awareness shaping proper consumer preferences. The future of transport will depend on both the carriers and the customers.
Mając dane ilościowe i jakościowe, podjęto próbę zbadania zależności i związków zachodzących między rozwojem transportu a efektywnością wykorzystania zasobów paliwowych, co stanowiło zasadniczy cel artykułu. Przeprowadzona analiza pozwoliła stwierdzić, że transport drogowy zyskał obecnie szczególny status w życiu codziennym społeczeństwa. Wzrost mobilności mieszkańców Europy spowodował, że samochody osobowe są aktualnie w największym stopniu odpowiedzialne za potrzeby energetyczne transportu drogowego. Stało się tak mimo poprawy efektywności energetycznej tych samochodów oraz wzrostu przewozów towarowych. Prognozowany dalszy wzrost przewozów towarowych spowoduje dalsze zmiany w strukturze zużycia energii przez transport samochodowy. Mimo wysokiej dynamiki poprawy efektywności energetycznej napędów samochodów ciężarowych, udział zapotrzebowania na paliwo przez te samochody będzie wzrastał w całkowitym zapotrzebowaniu na paliwo sektora transportu drogowego. Jednocześnie zużycie energii przez samochody osobowe zmniejszy swój udział w całkowitych potrzebach paliwowych transportu samochodowego. Poprawa efektywności energetycznej transportu osobowego i ciężarowego nie zrównoważy wzrostu zapotrzebowania na energię w transporcie drogowym. Przedstawione powyżej prawidłowości wyznaczają kluczowe wyzwanie stojące przed systemem transportowym – sprostanie ciągle rosnącemu zapotrzebowaniu na energię. Istotną kwestią w realizacji założeń zrównoważonego rozwoju transportu nie jest tylko rozwój technologii, lecz ludzka świadomość kształtująca właściwe preferencje konsumentów. Od przewoźników i klientów zależny będzie kształt transportu w przyszłości.

The paper presents the concept of repowering in existing power plant. Among technologies for existing steam power plants, the hot windbox repowering is the fastest way to respond to the energy demand, improve efficiency and reduce the pollutants emissions. Thermodynamic analysis of power plant model with fossil boiler before and after hot windbox repowering, has been investigated using commercial software. The purpose of this work is to understand and analyze the effect of hot windbox repowering on 387 MW fossil fuel power plant as well as the effect of additional heat exchangers, which have been installed parallel with regeneration system to use the heat of boiler exhaust gases. In this way, after repowering the summary power of power plant in base load is 615 MW, which has been reached adding gas turbine (176.9 MW). To analyze the model, calculations were performed in 3 stages: 1) calculation and comparison of the thermodynamic parameters as well as carbon dioxide emissions of power plant model before and after repowering, 2) analysis of the optimal value of feed water mass flow through heat exchangers installed after economizer, 3) calculation of thermodynamic parameters in values 100%, 90%, 80% and 75% of fossil boiler heat loads.

Opis:
Research background: Intensive economic growth in Russian regions during recent decades has been associated with numerous environmental issues, particularly increasing CO2 emissions, as well as income inequality. To achieve sustainable development, it is necessary to resolve these issues. Purpose of the article: To shed light on the impact of income inequality on CO2 emissions based on Russian regional data covering the years 2004?2018. Methods: Gini index and decile dispersion ratio are used to measure income inequality. To study the impact of income inequality on CO2 emissions in the Russian regions, we estimate econometric models with fixed and random effects and apply GMM method. We test the hypothesis of the environmental Kuznets curve to determine the impact of economic growth on CO2 emissions. Findings & value added: The results show that CO2 emissions increase in tandem with growth in income inequality between 10% of people with the lowest income and 10% of people with the highest income. Simultaneously, CO2 emissions decrease with growth of Gini coefficient. The hypothesis of the Environmental Kuznets Curve was confirmed based on GMM method. Our findings underscore that the activities of the extraction and manufacturing sectors, as well as energy consumption, increase CO2 emissions. The chief significance of this paper is the finding that large income gap between extremely rich and extremely poor population cohorts increases CO2 emissions. This implies that economic policy aimed at reducing income inequality in Russian regions will also reduce CO2 emissions, especially if accompanied by increased use of environmentally friendly technologies. From the international perspective, our research can be extended to study other countries and regions.

W artykule przedstawiono, w jakim stopniu wykonanie dozwolonych przez konserwatora prac związanych z ociepleniem bryły zabytkowego, murowanego kościoła spowoduje zmniejszenie rocznego zużycia energii na cele grzewcze oraz ograniczy występowania w kościele różnych, niekorzystnych zjawisk związanych z przepływem ciepła i wentylacją. Analizowano również, o ile po termomodernizacji może zmniejszyć się zużycie paliwa tj. gazu lub węgla na cele grzewcze i tym samym emisja CO2 do atmosfery. Porównano efekty takiej termomodernizacji, przy stałym i okresowym sposobie ogrzewania kościoła oraz gdyby był on zlokalizowany w różnych miastach Polski. Do analizy przyjęto bryłę zabytkowego kościoła znajdującego się w gminie Zarszyn.
The article presents the extent to which the execution of works permitted by the conservator and associated with insulation of the historical, stone church will reduce the consumption of annual energy for heating purposes and will reduce the occurrence in the church of different unfavourable phenomena associated with heat and ventilation. It was also analysed how much the consumption of fuel for heating (gas and coal) may be reduced and thus the reducing CO2 to the atmosphere. The effects of such thermomodernisation have been compared, with constant and periodic method of heating of the church and for different church locations, in different Polish cities, towns. For analytical purposes a solid of the historical church located in the Zarszyn borough was adopted.

Za pomocą diagramu Czekanowskiego podzielono kraje na grupy jednorodne pod względem badanych cech. Dla wszystkich badanych państw oraz dla poszczególnych grup oszacowano modele ekonometryczne, aby sprawdzić istotność wpływu rozwoju poszczególnych rodzajów transportu na zanieczyszczenie powietrza. Potwierdziła się hipoteza badawcza, że zbiorowy transport osób ma korzystny wpływ na jakość powietrza.
The article examines the development of transport of goods and people in 15 EU countries between 2000 and 2014. Transport was divided into road, rail and air transport. Using the Czekanowski’s diagram the countries were divided into homogeneous groups in terms of the examined characteristics. Econometric models have been estimated for all countries studied and for each group to examine the significance of the impact of the development of particular types of transport on air pollution. The research hypothesis confirms that collective transport of people has a beneficial effect on air quality.
