Implementace biopotravin a lokálních potravin do společného stravování
MOUČKA, Petr
Various efforts to reduce greenhouse gas emissions are increasingly being seen around the world. Agriculture and the food sector contribute to greenhouse gas emissions, and therefore it is necessary to introduce measures aimed at their mitigation. Organic food and short supply chains are associated with lower environmen-tal impacts, and school canteens offer great scope for mitigating climate change just by implementing these measures. An often-mentioned problem is the higher financial costs of buying organic or locally produced food. This work shows that, in the case of choosing the right ingredients and involving the right logistics, the fi-nancial costs for one portion do not have to exceed 1.5 % of the price increase. The work also shows that the implementation of organic food is not necessarily as key to mitigating climate change as the implementation of local food. To apply these results to other cases, research focused on specific canteens and their possibilities for the supply of local food is necessary.

Vyhodnocení emisí amoniaku z chovu drůbeže ve vybraném zemědělském podniku
HES, Adam
This bachelor's thesis focuses on the assessment of ammonia emissions from agricultural operations and their potential impact on the environment and human health. The aim of the work is to analyze the factors affecting ammonia emissions and propose possible measures to reduce them. To achieve this goal, measurements of ammonia emissions were carried out using specialized sensors located in different places of the farm. At the same time, information was collected on the procedures and technologies used in animal husbandry and fertilizer storage. The analyzes carried out showed that the main sources of ammonia emissions in the analyzed agricultural company MTD Ústrašice are the breeding of farm animals and the application of fertilizers to the fields. We identified factors such as the type and size of animal husbandry, storage methods, and fertilizer application techniques that affect ammonia emission rates. Based on our findings, we propose the implementation of measures aimed at reducing ammonia emissions, such as optimizing fertilizer storage technologies, modifying procedures and using alternative animal husbandry methods. These measures should contribute to the protection of the environment and human health in the given agricultural enterprise.

The development of energetics in the Czech Republic during the following years
Musil, Miloš ; Kracík, Petr (referee) ; Toman, Filip (advisor)
This thesis analyses the current Czech energy sector. It describes its current state and outlines possible scenarios of its development in future years in the context of the energy transformation. The thesis seeks to analyse the current situation of the energy sector in the country, assess its strengths and weaknesses and identify opportunities and threats for future development. The thesis describes the different parts of the Czech energy sector, such as the electricity, gas, heating and oil industries, including production sources, consumption and emissions. Most emphasis is given to the electricity sector. The capacities and potentials of the different sectors are analysed alongside the possible future scenarios outlined. Part of the thesis is also focused on describing and explaining the composition and construction of electricity and gas prices in the Czech Republic. Emphasis is also placed on placing the Czech energy sector in the broader context of the energy sectors of European countries and includes various scenarios for the development of the electricity sector in Europe. In the context of the current geopolitical situation in Europe and the modernisation and transformation of this sector, it is necessary to build new energy sources.

Operation of electric vehicles, hybrid vehicles and vehicles with an internal combustion engine
Herzog, Radim ; Píštěk, Václav (referee) ; Kučera, Ondřej (advisor)
This bachelor's thesis deals with the comparison of different propulsion concepts and their consumption, efficiency, and amount of emissions produced during operation. Although electric vehicles do not produce any local emissions, it is necessary to consider that emissions are generated during the production of electricity in power plants. The main part of the thesis introduces the functional principles of individual propulsion systems. Furthermore, it describes the formation of exhaust gas emissions in combustion engines and outlines their limits. Subsequently, the amount of emissions produced by a power plant for the operation of a specific example of an electric vehicle and a hybrid vehicle is calculated. Finally, a comparison of emissions production from representative examples of each propulsion system is illustrated.

Predicting spark-ignition engine emissions
Jirout, Petr ; Böhm, Michael (referee) ; Štětina, Josef (advisor)
This diploma thesis deals with the possibility of predicting emissions of SI engines. The aim was to create an algorithm for predicting unburned hydrocarbons and carbon monoxide, based on ECU signals. The algorithm is based on practical experiments with SI engines. In the summary, the issues and the possible use of the created algorithm following the incorporation of EU7 are outlined.

Alternative Fuels for CI-engines
Matoušek, Martin ; Řehák, Kamil (referee) ; Dundálek, Radim (advisor)
The topic of this bachelor thesis is alternative fuels applicable in diesel engines. First, a brief introduction to the diesel engine is given, then the individual alternative fuels are described. The most important findings about these fuels are summarized and a comparison with diesel fuel is made. Finally, each fuel is evaluated in terms of its advantages, disadvantages and applicability in practice.

European emission legislation
Rytina, Matěj ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
The aim of this bachelor thesis was to write about exhaust emissions and their influence on environment, briefly sum issue of emission standards up and mainly sum existing facts about the “Dieselgate” affair up. I wanted to objectively evaluate this issue in my bachelor thesis. Asset of this thesis was mend to be in fact that this affair has not been academically covered yet.
