Opis:
Podczas produkcji zwierzęcej, która coraz bardziej się rozwija dochodzi do szkodliwych emisji gazowych. Emisje te dotyczą zarówno uciążliwych gazów odorowych jak i cieplarnianych. Powstające związki lotne przyczyniają się również do powstawania kwaśnych deszczów, eutrofizacji zbiorników wodnych i gleb, korozji w budynkach inwentarskich oraz uszkodzenia warstwy ozonowej. Wobec istniejącego problemu szuka się rozwiązań neutralizujących wpływ produkcji zwierzęcej na środowisko. Ponadto podejmuje się liczne działania na drodze żywieniowej oraz rozwiązań technologicznych. Techniki żywieniowe bazują na modyfikacji diety i wymagają stałego monitoringu utrzymywanych zwierząt. Z kolei rozwiązania technologiczne podejmują działania redukcji emisji gazów z budynków inwentarskich oraz podczas gospodarki odchodami zwierzęcymi. Proponowane sposoby utylizacji gnojowicy przynoszą zróżnicowane efekty jeśli chodzi o redukcję niebezpiecznych gazów. Wymagają one wdrożenia dodatkowych działań prowadzących między innymi do właściwego zagospodarowania odchodów zwierzęcych.
During the animal production, which is increasingly expanding, it comes to harmful gas emissions. These emissions relate to both greenhouse and odorous gases emissions. The resulting volatile compounds also contribute to the formation of acid rain, eutrophication of water aquens and soils, corrosion in livestock buildings and damage of the ozone layer. Considering the existing problem, solutions neutralizing the impact of animal production on the environment, are being looked for. Moreover, numerous activities in the way of nutritional and technological solutions are undertaken. Nutritional techniques are based on diet modification and require continuous monitoring of livestock animals. On the other hand, technological solutions are taking action to reduce emissions of gases from livestock buildings and slurry management. The proposed ways of disposing slurry result in different effects in terms of reduction of dangerous gases. They require the implementation of additional actions leading, among other things, to the proper animal waste disposal.

Opis:
Rozwój intensywnej produkcji zwierzęcej przyczynia się do skażenia środowiska naturalnego. Jednym z czynników powodujących degradację gleb, wód i atmosfery są odchody zwierzęce. Bezściółkowy system generuje odchody w postaci gnojowicy, która nieracjonalnie zagospodarowana staje się źródłem emisji gazowych. Z budynków inwentarskich podczas magazynowania oraz nawożenia gruntów rolnych dochodzi do emisji zarówno gazów odorowych, jak i cieplarnianych. Emisja amoniaku i siarkowodoru jest uciążliwa dla lokalnej społeczności. Niekorzystnie wpływa również na dobrostan utrzymywanych zwierząt i osób pracujących w budynkach inwentarskich, co może prowadzić w skrajnych przypadkach do zatrucia. Z kolei emisja metanu i podtlenku azotu pogłębia efekt cieplarniany, odpowiadający za zmiany klimatu. Dodatkowo, podtlenek azotu powoduje uszkodzenie warstwy ozonowej.
Pollution of the natural environment is caused by the animal production. The intensification of animal farming results from enrichment of society and population growth. Both processes are observed on the territories of both developed and developing countries. Farm animals’ breeding is inseparably connected with gas emissions, which are the cause of the natural environment pollution. These emissions originate when the animal fodder undergoes the process of digestion. Another source of gas emission are animal faeces, which are generated in form of slurry, during the intensive animal production process. Enormous amounts of slurry are produced in the intensive waste storage conditions. It is used as a natural fertilizer, but it requires rational management, which would help to reduce the amount of emitted gases. Livestock housings and slurry containers are the most responsible sources of gas emissions. The nuisance of animal productions is connected with the emission of odour gases. They cause the decrease in the efficiency of animal production. This is also the group of gases, which are very bothersome for the local community. Hydrogen sulphide and ammonia are two representatives of odour gases. These two gases cause upper respiratory tract problems and eyes’ irritation. The exposure to greater amounts of hydrogen sulphide and ammonia may even lead to death. Both also lead to corrosion. Ammonia is the cause of acid rain, and both water and soil eutrophication. Furthermore, in agriculture, cattle’s intestinal fermentation is responsible for the highest methane emission to the environment. The emission of methane occurs also during the management of faeces. Slurry produces the biggest amount of ammonia. On this account, it is required to use it as a substrate during the fermentation process in the biogas plants. Another greenhouse gas, emitted to the atmosphere in the process of farm animals’ breeding, is nitrous oxide. It is not a widely emitted gas, but it severely deepens the greenhouse effect. Additionally, nitrous oxide contributes to the damage of the ozone layer, thereby enabling the harmful UV light to reach the Earth. In case of the threat that gas emissions brings to the natural environment, certain actions contributing to gas reduction, should have been undertaken. Slurry is being processed during its storage. That helps to limit both the greenhouse and odour gases emissions to the natural environment.

Opis:
For a long time, experts have been emphasizing that we are in an era, in which dangerous climatic changes are getting more and more notable. We have been witnessing large climatic changes, caused by greenhouse gases, for several years. The question is no more “Are there climatic changes or are there not?”, nor “Are they being accelerated by human actions or are they not?” The fact is, the climate is changing more and more rapidly and that extreme weather conditions are becoming a daily matter. Furthermore, even if we stopped polluting the atmosphere immediately, the processes triggered by human-caused pollution would be going on for several decades. Modern logistic systems cannot operate without means of transport which enable the realization of transport. They form a transport system that makes the function of other economic systems possible. The use of different ways of transport has a bad influence on the environment in which we daily live and work. The damage of transportation has a bad influence on human health and nature, too. For that reason, we cannot treat the safety of the transportation means only through the technical impeccability of the devices which make possible direct execution of particular technological phases in different traffic subsystems. Ecological impacts of particular traffic subsystems are very complex, they have a long-term impact on our everyday existence and despite that we still do not devote enough attention to this. We have been aware that traffic, especially road and air traffic, is one of the largest sources of emissions of harmful exhaust gases of combustion engines and particles into the environment. The environmental impact of traffic is especially large due to greenhouse gases, which are part of exhaust gases being produced by internal combustion engines. In addition to that, there are many more toxic components in exhausted gases.

Opis:
An overview of long-term, sysiematic observations of trace gas composition of the atmosphere over southern Poland is given. Three major greenhouse gases (CO2, CH4, N2O) and selected halocarbons (freons F-11, F-12 and F-113; chloroform; 1,1,1-trichloroetane; carbon tetrachloride; sulphur hexafluoride and trifluoromethyl sulphur pentafuoride) were monitored. Measurements were performed at two locations of contrasting characteristics: (1) the high-mountain site Kasprowy Wierch, High Tatras, representing atmospheric conditions relatively free of local influences, and (2) two sites located in the Kraków agglomeration, representing a typical urban atmosphere. The data available for Kraków and Kasprowy Wierch were compared with the Mace Head data, representing a marine regional background. The impact of continental sources for some of the measured gases is clearly seen in the Kraków and Kasprowy Wierch records. The mean offset between CH4 concentrations recorded at Kasprowy Wierch and at Mace Head for the period 1998-2012 is 20.7 ppb and stems from continental emissions of this gas originating mainly from anthropogenic activities (leaks of natural gas distribution networks, landfills, livestock). For N2O, a similar offset of ca. 1 ppb for the period 2009-2012 was observed. Although the long-term concentration trends of selected halogenated compounds measured in Kraków coincide in general with the respective trends in Mace Head data, the Kraków records contain numerous spikes and periods of enhanced concentrations, reflecting the impact of local sources of these compounds. The impact of a legislative framework enforced in Poland in July 2002, regulating the trade, storage and disposal of ozone-depleting substances, is visible in the Kraków record of halogenated compounds.

Opis:
Emissions of greenhouse gases, such as carbon dioxide, methane, dinitrogene monoxide, water vapours and ozone was constant until the end of eighteenth century, and then began to increase. This increase was particularly steep after 1950 and continues until today. It is estimated, that changes in greenhouse gas concentrations in the air, which lasts for more than 200 years, stemmed largely from human activities, including the development of agriculture, transport and industry. The article discusses the problem of the greenhouse effect in terms of emissions of selected gases and components from the motor vehicles. It presents the results of pollutants emissions measurements, including greenhouse gas emissions from vehicles, in some research tests, curried out on the chassis dynamometer. There is assessed the impact on greenhouse gas emissions from different engine sources (exhaust system, fuel system, and crankcase) due to the following fuels: LPG, CNG, petrol, diesel oil and biodiesel. This article is a fragment of greater work devoted determination of emission indicators for greenhouse gases useful in calculation of total emissions by selected transport sectors. There are two interesting conclusion of this work: the first is that for diesel engine significant part of greenhouse gas emissions have PM emissions and the second that for older spark ignition engines equipped with open type fuel systems very important part of these emissions have hydrocarbon emissions from fuel system.

Opis:
Livestock buildings are an important source of ammonia, methane and nitrous oxide. In naturally ventilated buildings for dairy cattle interaction of weather conditions and microclimate parameters in livestock buildings have an impact on the emission of ammonia and greenhouse gases. The aim of the study was to determine the effect of the seasons on the emission of greenhouse gases (CH4, N2O) and ammonia from barns for dairy cows. The study was conducted in 6 free-stall barns located in the Wielkopolska Voivodship, during: spring, summer and fall. The median of CH4 emission factor was 14.8±2.3 g·h-1·cow-1 in spring, 16.9±3.2 g·h-1·cow-1 in summer, 17.3±2.1 g·h-1·cow- in fall. For N2O and NH3 values were 0.085±0.067 g·h-1·cow-1 in spring, 0.120±0.060 g·h-1·cow-1 in summer, 0.062±0.049 g·h-1·cow-1 in fall and 1.13±0.34 g·h-1·cow-1 in spring, 1.17±0.45 g·h -1·cow-1 in summer, 0.77±0.37 g·h-1·cow-1 in fall, respectively. The analysis for all barns showed statistically significant differences in the values of emission factors between seasons (α = 0.05). For NH3 and CH4 they were not observed only between spring and summer, and for N2O between spring and fall (α = 0.05).
Budynki inwentarskie są głównym źródłem amoniaku, metanu i podtlenku azotu. W naturalnie wentylowanych obiektach dla bydła mlecznego wzajemne oddziaływanie warunków pogodowych oraz parametrów mikroklimatu wewnątrz budynków inwentarskich kształtuje emisję amoniaku i gazów cieplarnianych do otaczającego je środowiska. Celem pracy było określenie wpływu pór roku na emisję gazów cieplarnianych (CH4, N2O) i amoniaku z kilku obór dla krów mlecznych. Badania przeprowadzono w 6 oborach wolnostanowiskowych zlokalizowanych w województwie wielkopolskim, w trzech seriach: wiosennej, letniej oraz jesiennej. Mediana wskaźnika emisji CH4 wynosiła 14.8±2.3 g·h-1·szt.-1 wiosną, 16.9±3.2 g·h-1·szt.-1 latem i 17.3±2.1 g·h-1·szt.-1 jesienią. Dla N2O i NH3 wartości te wynosiły odpowiednio 0.085±0.067 g·h-1·szt.-1 wiosną, 0.120±0.060 g·h-1·szt.-1 latem i 0.062±0.049 g·h-1·szt.-1 jesienią oraz 1.13±0.34 g·h-1·szt.-1 wiosną, 1.17±0.45 g·h-1·szt.-1 latem i 0.77±0.37 g·h-1·szt.-1 jesienią. Ogólna analiza dla wszystkich obór wykazała statystycznie istotne różnice w wartościach wskaźników emisji między porami roku (α=0.05). W przypadku NH3 i CH4 nie zaobserwowano tych różnic jedynie dla wiosny i lata, a w przypadku N2O dla wiosny i jesieni (α=0.05).

Natural gas is being considered as a “bridging fuel” that plays a crucial role in implementing the transition to a low-carbon economy and society. This study reviews an aspect of the natural gas industry that has been neglected for far too long, in spite of the growing importance of countering global warming and climate change. Reducing methane emissions from natural gas production, processing, transportation and consumption is becoming a more and more important aspect of reducing greenhouse gas emissions, and may contribute significantly to the goals of the United Nations Climate Change Conference of 2015. The key question this study aims to answer is to what degree does a stronger emphasis on natural gas consumption contribute to the fulfilment of the climate goals of the Paris Agreement per se? Is promoting natural gas consumption really the key to avoid a climate catastrophe? Is there sufficient time left to avoid such a catastrophe?

Opis:
Poland, due to the ratification of the Kioto Protocol, is obliged to diminish the emission of greenhouse gases. One of the possible solutions of this problem is CO2 sequestration (CCS – carbon capture and storage). Such an option is a priority in the European Union. On the other hand, CO2 sequestration may be potentially risky in the case of gas leakage from underground reservoirs. The most dangerous event may be a sudden release of the gas onto the surface. Therefore, it is very important to know if there is any escape of CO2 from underground gas reservoirs, created as a result of sequestration. Such information is crucial to ensure safety of the population in areas located above geological reservoirs. It is possible to assess the origin of carbon dioxide, if the measurement of radiocarbon 14C concentration in this gas is done. If CO2 contains no 14C, it means, that the origin of the gas is either geological or the gas has been produced as a result of combustion of fossil fuels, like coal. A lot of efforts are focused on the development of monitoring methods to ensure safety of CO2 sequestration in geological formations. A radiometric method has been tested for such a purpose. The main goal of the investigations was to check the application possibility of such a method. The technique is based on the liquid scintillation counting of samples. The gas sample is at first bubbled through the carbon dioxide adsorbent, afterwards the adsorbent is mixed with a dedicated cocktail and measured in a low-background liquid scintillation spectrometer Quantulus. The described method enables measurements of 14C in mine and soil gas samples.

Indonesia is the country with the greatest potential for sago in the world. This research is intended to determine the carbon footprint of sago starch produced from a semi-mechanical process. The calculation was carried out using the LCA approach with the system boundary of cradle to gate. The process steps were carried out in a combination of manual work and diesel-driven engines. The inventory data on material, energy input flows and emissions were obtained from 3 samples of typical medium-scale semi-mechanical sago mills. It was found that the carbon footprint of the sago produced from semi-mechanical processes was 37.9±0.6 kgCO2 eq per 1 ton of dried sago starch. Further analysis shows that 62% of the carbon footprint comes from the extraction stage and 38% from the transportation. It can be estimated that the amount of greenhouse gas emissions from the semi-mechanical sago starch production in Indonesia for 2018 reached around 2,617,639 kg CO2 eq.

A lot of attention is nowadays devoted to the problem of generally defined ecology. It is absolutely essential in case of systems and sources generating heat due to their direct influence on the environment through emitting post-process products to the atmosphere which are, most frequently a result of combustion. Therefore, constant searchers are made to optimize the operation of heat sources and to acquire energy from sources for which the general balance of carbon dioxide emission is zero or close to zero. This work compares the emissions of equivalent CO2 from selected systems with the following heat sources: coal, gas furnace, heat pump, and refers results of the analysis to aspects connected with regulations concerning environmental protection. The systems generating thermal energy in the gas furnaces, coal, biomass, as well as the compression heat pumps with the lower heat source as ambient air or ground were taken under consideration, as well as centralized systems for the production of heat based on the combustion of coal, gas, oil, and biomass. the Emission of carbon dioxide for the installation of cogeneration and absorption heat pump were also calculated. Similarly obtained amount of extra emission necessary for the proper operation maintenance of heating devices via the supplied electricity from external source, the mostly fuel-fired power plants for fuels as previously mentioned. The results of the calculations were presented in tables and graphs.

Nowadays, the environmental aspects of transport are very actual issues, mainly the energy consumption and GHG production. The priority of EU transport strategy is to decrease the negative environmental impacts of all transport modes. The article discusses the calculation of the energy consumption and production of greenhouse gases in transport from both the primary and secondary points of view. This means, that it reflects the implications on the environment not only while operating the vehicle, but also during production, refining, distribution and storage of the fuel used in transport. The calculation is done by using the methodology of the standard EN 16 258:2012. This standard is used on all cars using various types of propellants. The results of the calculation show in a non-discriminatory manner the energy effectiveness of the individual types of fuel, as well as the rate of their production of greenhouse gases expressed in a comparison unit of equivalent CO2e.

Opis:
The passage of more than a decade since the system was introduced and 3 years since the beginning of the third trading period (Phase 3) has coincided with a period of aggravating crisis (referred to even as a breakdown) and recurring doubts as to whether the system is capable of achieving the desired goal or perhaps it should be replaced with another instrument. However, no concept of such an instrument has been proposed yet, which would enable harmful emissions to be reduced efficiently and cost-effectively instead of the current EU ETS. Ten years after the launch of the system and three years into Phase 3, intensive work started on a structural reform of the EU ETS. The aim of this article is to give account of the state of research in the reform, present the principal directions and objectives, and to provide an evaluation.

Opis:
Na podstawie danych krajowych i zagranicznych oszacowano poziom i strukturę emisji gazów cieplarnianych (GHG) w rolnictwie polskim. Według danych Krajowego Ośrodka Bilansowania i Zarządzania Emisjami (KOBiZE) z rolnictwa polskiego pochodziło w 2015 r. 7,68% krajowej emisji GHG (bez uwzględnienia emisji spowodowanych zużyciem energii w rolnictwie), w tym 0,16% dwutlenku węgla (CO2), 29,81% metanu (CH4) i aż 78% podtlenku azotu (N2O). Po uwzględnieniu emisji GHG w wyniku zużycia energii w rolnictwie udział tego sektora gospodarki narodowej w krajowej emisji CO2 e wyniósł 10,50%. W strukturze emisji GHG w rolnictwie polskim według rodzaju emitowanych gazów udział dwutlenku węgla wyniósł 27,0%, metanu - 35,8%, podtlenku azotu - 36,5%, gazów fluorowanych – 0,7%, a według źródeł emisji: z fermentacji jelitowej - 30,7%, zagospodarowania odchodów zwierzęcych - 9,1%, produkcji roślinnej - 32,6%, zużycia energii - 27,5%, a pozostałych źródeł - 0,1%.
Basing on national and foreign data, the level and structure of greenhouse gas (GHG) emission in Polish agriculture has been estimated. According to the National Centre for Emission Management (KOBiZE), in 2015 the share of Polish agriculture in national GHG emission (without emissions resulted from energy use in agriculture) amounted to 7.68%, of that CO2 - 0.16%, CH4 - 29.81% and N2O - 78%. After addition of GHG emission caused by energy use in agriculture, the share of this sector in the national greenhouse gas emission (in CO2 equivalent) amounted to 10.50%. In the GHG emission structure in Polish agriculture by gases, the share of CO2 amounted to 27.0%, CH4 - 35.8%, N2O - 36.5%, and fluorinated gases - 0.7%, and by sources - enteric fermentation 30.7%, manure management - 9.1%, crop production - 32.6%, energy - 27.5%, and other sources -0.1%.
