The Impact of Passenger Cars on Air Pollution

The impact of passenger cars on air pollution is particularly noticeable in cities, where road traffic is heavy throughout the year. Passenger cars, which dominate urban roads, account for a significant share of air pollution, affecting residents’ health and quality of life.

In areas with heavy traffic, such as city centres, passenger cars can account for 30% to as much as 60% of air pollutant emissions. Pollutants such as carbon dioxide, nitrogen oxides and particulate matter not only deteriorate air quality but also contribute to the formation of smog, which can be particularly severe in winter, when additional emissions come from building heating.

In urban areas, emissions from passenger cars are a major source of photochemical smog, which forms when vehicle exhaust gases react with other substances in the air under the influence of sunlight.

Smog is a serious health concern that affects the respiratory system and increases the risk of asthma, heart disease and respiratory infections. In addition, inhaling particulate matter and nitrogen oxides can negatively affect the body’s overall immune response. This is particularly concerning for children, older people and those living with chronic conditions.

How can we reduce the impact of passenger cars on the atmosphere?

Use public transport

Reducing the number of cars on the roads is a simple way to reduce transport-related emissions and traffic congestion.

Switch to low-emission vehicles

Choosing hybrid, electric or hydrogen-powered vehicles can reduce the amount of pollutants generated and help improve air quality.

Eco-driving

Eco-driving involves smooth acceleration, maintaining a steady speed and avoiding unnecessary stops. These practices can reduce fuel consumption by up to 20%, thereby reducing pollutant emissions.

Introduce low-emission zones in cities

Restricting the use of combustion-engine vehicles in designated areas can improve air quality in city centres and reduce the risk of health problems associated with air pollution.
