On September 19, Minsk / Olga Belyavskaya - BELTA /. The "Car-Free Day" campaign will be held in Belarus on September 22, BELTA was informed at the Ministry of Natural Resources and Environmental Protection. The event is aimed at drawing public attention to the problems of air pollution in the country's cities. Despite the fact that the road transport complex is the most important sector of the economy, satisfying the needs of society and the population in transportation, it is also the largest polluter of the environment. On a national scale, the share of transport in the total emissions of pollutants into the atmosphere from all sources reaches 72%. Thanks to the measures taken in Belarus to reduce the harmful impact of transport on the environment, last year it was possible to reduce emissions of pollutants into the atmospheric air from mobile sources, which in general for the republic amounted to 942.3 thousand tons and decreased compared to the 2009 level by 194.9 thousand tons, or by 17.1%, with an increase in the fleet of motor vehicles during this period by 4.8%. In 2010, on average per day in Belarus, about 2.6 thousand tons of pollutants were emitted into the atmosphere with exhaust gases (in 2009 - about 3 thousand tons), including about 430 tons for Minsk. In 2010, 209,012 motor vehicles were imported into Belarus, including 193,710 units imported by individuals. Of the total number of imported cars, 10.2% were cars under 3 years old, 33.5% were from 3 to 7 years old, and more than 56.3% were over 7 years old. On average, when a car travels 15,000 km per year, it burns more than 2 tons of fuel and consumes about 30 tons of air. In this case, about 700 kg of carbon monoxide (CO), 400 kg of nitrogen dioxide, 230 kg of hydrocarbons and other pollutants, the total number of which is more than 200 items, are emitted into the atmosphere. Annually, about 1 million tons of pollutants are emitted into the atmospheric air with exhaust gases from mobile sources.
