Motor transport is one of the factors producing the highest emission of polluting substances into the atmospheric air in Ukraine. In 1998 it emitted into the atmospheric air 1,884,500 tons of pollutants, which makes up 31% of the total emission volume in Ukraine. Over 63% of the lead, 54% of the carbon monoxide, 36% of the hydrocarbons and 25% of the nitrogen oxides of the total quantity of these substances in the country are emitted by vehicular sources.

In 1998 the vehicular pollution in most regions of the country was 60% higher than the total volume of emissions in the region, specifically in Zakarpattya (82%), Zhytomyr (81%), Odesa and Volyn regions (78%), in the Autonomous Republic of the Crimea (76%), and in Chernivtsi (74%), Ternopil (70%), Sumy and Mykolaiv (63%), and Khmelnytskyi (62%) regions.

Over the last years vehicular pollution has gradually decreased. However, when making more precise the assessment of the amount of fuel used by individual transport, it appeared that in 1998 the volume of polluting substances emitted into the atmospheric air was 32% higher than in 1997. Thus, emissions of polluting substances into the atmospheric air from vehicular sources increased in most cities of Ukraine. So, in the cities of Vinnytsa, Dniepropetrovsk, Dnieprodzerzhynsk, Kryvyi Rig, Marganets, Nikopol, Gorlivka, Donetsk, Debaltseve, Dzerzhynsk, Druzhkivka, Kostyantynivka, Kramatorsk, Makiyivka, Mariupol, Kirovograd, Oleksandriya, Svitlovodsk, Yevpatoriya, Sevastopol, Krasnoperekopsk, Antratsyt, Alchevsk, Rubizhne, Izmail, Kharkiv, and Chernigiv emissions of polluting substances into the atmosphere from motor transport increased more than 60% in 1998 as compared to 1997.

In most cities of Ukraine: Vinnytsa, Lutsk, Uzhgorod, Zhytomyr, Ivano-Frankivsk, Fastiv, Kirovograd, Lviv, Rubizhne, Severodonetsk, Odesa, Izmail, Poltava, Sumy, Ternopil, Khmelnytskyi, Chernivtsi and Uman, and in the cities of the Crimea: Yevpatoriya, Sevastopol, Simferopol and Yalta vehicular pollution makes up 60-90% of the total quantity of emissions.
