What You'll Learn

Austria's Air Pollution Control Act
The Act establishes an Austria-wide measuring network for air pollutants and identifies exceedances of limit or target values. Standardised air pollution threshold values have been set at the federal level for pollutants such as CO, NOx, SO2, lead, benzene, and suspended particulate matter. To ensure compliance with these values, the Provincial Governor must work out a programme to reduce emissions in the event of exceedances. This programme may include measures such as the use of low-emission fuels, restrictions on machines with high specific emissions, and temporal and spatial restrictions on traffic.
The Environment Minister is required to submit a written report to the National Council every three years, detailing the state, development, and predictions for air pollutants and emissions, as well as the success of the measures taken under the Act. Citizens living or working in polluted environments have the right to take legal action to enforce the implementation of measures to improve air quality.
Austria has seen a decrease in particulate matter (PM10) exceedances in recent years, but exposure, particularly in urban areas, remains a concern. The main sources of air pollution are traffic, household heating, and industry. To address this, new targets for 2030 focus on reducing emissions from vehicles, industry, and agriculture, with maximum emission limits set for various pollutants.

Nitrogen dioxide pollution
Nitrogen dioxide (NO2) pollution is a significant issue in Austria, with around 8,200 premature deaths occurring annually due to air pollution. This colourless, reactive gas is a harmful pollutant that can have detrimental effects on both human health and the environment.
NO2 pollution in Austria is predominantly caused by traffic, particularly diesel emissions, which contribute to more than half of the country's nitrogen oxide pollution. The State of Salzburg found a reduction of up to 40% in nitrogen dioxide pollution due to decreased traffic during the coronavirus crisis. However, despite these short-term improvements, Austrian air quality still falls short of World Health Organization (WHO) guidelines. In 2024, the majority of Austrian measuring stations reported NO2 levels exceeding WHO recommendations. The highest NO2 pollution levels were recorded in Vomp on the A12, followed by Graz, Vill, Enns, Linz, and Vienna's Hietzinger Kai. Tyrol, Salzburg, and Vienna are the regions with the highest nitrogen dioxide pollution levels in Austria.
To address the issue, Austria has set new targets for 2030, aiming to reduce vehicle, industry, and agricultural emissions. The country has also established maximum emission limits for various pollutants, including nitrogen oxides (NOx). The domestic environmental technology sector plays a crucial role in providing solutions to minimise air pollutants, and Austria's air pollution control regulations, such as the immission control law and the air quality directive, further contribute to managing NO2 emissions.
The harmful effects of NO2 pollution are not limited to Austria but extend across Europe. According to the European Environment Agency, air pollution is the continent's most significant environmental health problem, with nitrogen dioxide, particulate matter, and ozone causing approximately 400,000 premature deaths in Europe annually.

Fine dust pollution
The health risks associated with fine dust pollution are severe, with the World Health Organization classifying it as the greatest environmental risk to human health. It is linked to various lung diseases, heart attacks, and is a known class 1 carcinogen. The small particles in fine dust pollution can infiltrate the body and cause damage to the lungs and other organs, increasing the risk of COVID-19 and other respiratory issues.
In Austria, the primary sources of fine dust pollution are motor vehicle traffic, heating systems, and industrial emissions. Households with biomass heating, particularly those using log wood stoves and tiled stoves, are the largest contributors to fine dust pollution. Additionally, nitrogen oxides (NOx) are prominent pollutants in Austria, resulting from the high-temperature combustion of combustibles and fuels.
To address the issue of fine dust pollution, Austria has set targets for 2030, aiming to reduce emissions and improve air quality. The country must achieve a 69% reduction in emissions by 2030, focusing on vehicle, industry, and agricultural emissions. The primary goal is to halve the health costs associated with air pollution and support regional authorities in maintaining healthy air quality. This includes setting maximum emission limits for pollutants such as sulphur dioxide (SO2), nitrogen oxides (NOx), and fine dust PM2.5, specifically targeting the elimination of black carbon (BC).
The COVID-19 pandemic provided a unique perspective on the impact of human activity on air pollution. Satellite images from March 2020 showed a significant decrease in air pollution in Austria due to reduced traffic and industrial activity. This temporary improvement in air quality underscores the importance of implementing long-term solutions to combat fine dust pollution and protect the health and well-being of Austria's population.

Traffic and industry emissions
Austria's Air Pollution Control Act is the central law for maintaining clean air and controlling air pollution. The Act aims to protect human health and the environment from air pollutants, reduce air pollutants, and improve air quality. According to the European Environment Agency, air pollution is the most pressing environmental health issue in Europe, with around 400,000 premature deaths occurring annually due to particulate matter, nitrogen dioxide, and ozone. Cities and metropolitan areas are particularly vulnerable to the effects of air pollution.
To address traffic-related emissions, Austria has implemented measures such as temporal and spatial restrictions on traffic. The Air Pollution Control Act also plays a crucial role in managing these emissions. When threshold or target values for air pollutants are exceeded, the Provincial Governor is responsible for identifying the status quo and developing a programme to reduce emissions in designated "redevelopment areas." These measures aim to ensure compliance with the Air Pollution Act and EU standards.
Industry emissions are also addressed by the Air Pollution Control Act, which mandates the use of low-emission fuels and imposes restrictions or prohibitions on machines with high specific emissions. Additionally, Austria has set new targets for 2030 to reduce the health impacts of air pollution and support regional authorities in maintaining healthy air quality. These targets include maximum emission limits for sulphur dioxide (SO2), nitrogen oxides (NOx), volatile organic compounds (VOCs), ammonia (NH3), and particulate matter (PM2.5). By implementing these measures, Austria is striving to improve air quality and protect the health and well-being of its citizens.
