CzechCarbo - studium cyklu uhlíku v terestrických ekosystémech ČR
Ústav systémové biologie a ekologie AV ČR, České Budějovice ; Marek, Michal V.
Obsahem monografie je problematika globální změny klimatu, která je zde pojímána jako předmět odborné analýzy v rámci tří problémových okruhů: atmosféra - ekosystém - lidská společnost. Okruh atmosféra je zúžený na problematiku vývojových scénářů a okruh ekosystém na problematiku lesa. Je pojednána nová funkce lesa jako úložiště uhlíku. Byly získány unikátní výsledky s velmi cennou vypovídající hodnotou, které jsou využitelné pro lesnický a krajinářský výzkum i praxi. Kapitoly: Globální změna klimatu, Scénáře vývoje globální klimatické změny, Ekofyziologické předpoklady úložiště uhlíku ve fytomase, Toky uhlíku mezi ekosystémem a atmosférou, Les, uhlík a lesnictví ČR v podmínkách měnícího se prostředí, Zásoby uhlíku ve vegetaci České republiky a modelová uhlíková bilance krajiny, Vnímání globálních ekologických změn ve společnosti, Vázání uhlíku lesními ekosystémy a jeho místo v systému celospolečenských funkcí lesů.

Effect of flash ads on the environment and its comparison with the production of PET bottles
Krejčí, Martin ; Koblovský, Petr (advisor) ; Rod, Aleš (referee)
This bachelor thesis examines the impact of online advertisments created using Flash technology on the environment in the U.S. and then compares it to influence of production of PET bottles on the environment in the U.S.. The thesis describes the functioning of the flash ads. In the analysis there are compared the carbon footprint left-out of the difference in electricity consumption in the enabled and disabled Flash ads and production of PET bottles. The aim of the analysis is to compare the costs of flash advertising and PET bottles in term of environment and to consider revenues resulting from them and to answer the question whether the flash advertisement market is not regulated only because it does not seem originally to damage the environment as much as PET bottles does, and if it should not be regulated.

Gaseous products of microbial decomposition of organic pollution in constructed wetland used for wastewater treatment.
ŠTĚPÁNEK, Jindřich
This master thesis is dealing with monitoring of gaseous products of microbial decomposition of organic pollution in constructed wetland. This wetland was used for wastewater treatment in a village Slavošovice, Czech Republic. Emissions of CO2, CH4 and N2O were measured in one treatment bed of the system. The emissions were quantified, their seasonal course was followed, and the main factors affecting gaseous emissions were identified. Only 3 % of total C emissions were in form of methane, N2O emissions were negligible and only 1,5 % of nitrogen denitrified were in form of N2O. Carbon and nitrogen balances of the system were estimated.

Current state and perspectives on taxation of motor vehicles in the EU
John, Jiří ; Láchová, Lenka (advisor) ; Teklý, Lukáš (referee)
Bachelor thesis focuses on the issue of taxation of motor vehicles in the EU. Taxation of motor vehicles is harmonized these days on the grounds of elimination of market failures and motivation of customers to buy environmentally friendly cars. Work consists of 3 main parts. The first part describes the concepts of tax competition, coordination and harmonization. Furthermore, this section deals with the steps the EU, leading to a reduction of carbon dioxide emissions and their impact on the taxation of motor vehicles. The second part focuses on the taxation of motor vehicles used in selected member countries of the European Union. These countries tax cars based on emissions of carbon dioxide. In the third part of the paper is described the current state of taxation of motor vehicles in the Czech Republic. This section also deals with the future taxation of motor vehicles.
