Jak dlouho by musela jezdit stará škodovka, aby vyprodukovala tolik emisí, jako by vyprodukovala výroba jednoho nového ekologického auta?

This thesis covers primarily the detection of operating emission of an old Škoda Felicia car and the emission produced during the manufacturing of a new Toyota Prius, as the selected representative of an ecological car. The thesis also touches on hybrid technology in itself, the question of the greenness of hybrid cars, sphere of emission, but also related problems so called "scrapping" and its influence on environment and also current situation in automobile industry. The target of this study is calculation of operation time of an old Škoda Felicia during which the CO2 emission will reach the same amount of emission produced during manufacturing of a Toyota Prius. The objective is to point out incompetent and therefore not always serious comparison of cars greenness when only the operating CO2 is being compared. Other energy consumption and therefore also the greenhouse gases production is related with the car manufacturing, raw material extraction, petroleum processing and other economic sectors affected by production. Emission laboratory measurement executed by TÜV SÜD Czech discovered that the old Škoda produces 260m/km CO2 during its real running time. For the emission calculation was used an American model EIO-LCA created by Green Design Institute at Carnegie Mellon University that records ecological influence of car production, in stated amount, on all economy sectors. The outputs are quoted in CO2 equivalent. According to this model during manufacturing of 1 hybrid car 13.5 t of CO2e (equivalent CO2). is produced. Recalculation found out that the old Škoda Felicia could run for more than 5 years in order to produce as much emission as the manufacturing of new Toyota Prius third generation.
