Abstract

In the urban environment the car parking places are built in components. From the standpoint of air pollution view they can be treated as square pollution sources up to a point, because pollution is formed by mobile sources – vehicles. Pollution is emitted from cars coming into and leaving parking places, as well as during warming which is especially important in winter. Cold starts are the main constitution of all emissions emitted from parking places. Nevertheless, parked cars with hot engines also emit oil evaporations, especially if the cars are older then 10-12 years (84-88% of all vehicles in Riga belong to this group). In typical emission inventories the parking place and a collective garage are both included amon
