What You'll Learn
Oslo is the most polluted Norwegian city
While Norway is among the European countries with the lowest risk of premature death due to local air pollution, it still faces challenges in this regard. Air pollution is a complex issue, and various factors contribute to the overall air quality of a country.
Norwegian cities, including Oslo, have been impacted by air pollution, primarily due to particulate matter (PM), nitrogen dioxide (NO2), and ozone (O3). These pollutants can have significant health consequences for residents. Oslo, the capital city, has been identified as the most polluted Norwegian city in a recent ranking of Nordic capitals. It placed 66th out of 760 cities, significantly behind other Nordic capitals like Copenhagen, Helsinki, Stockholm, and Reykjavik.
The reasons behind Oslo's poor air quality are multifaceted. One factor is geography. The Oslo basin experiences less wind than other cities, leading to longer stagnation periods and the accumulation of pollutants in the atmosphere. Cold winters, with increased wood burning and road maintenance practices like gravel and salt sprinkling, also contribute to elevated levels of particulate matter. Additionally, emissions from road traffic, including exhaust fumes, are a significant source of nitrogen oxides (NOx) in Norwegian cities.
The health risks associated with air pollution are well-documented. Vulnerable groups, including children, the elderly, pregnant women, and those with existing respiratory and cardiovascular problems, are particularly susceptible to the adverse effects of air pollution. The Norwegian Institute of Public Health estimates that annually, approximately 185 and 115 deaths can be attributed to pollution from fine fraction PM2.5 and PM10, respectively. The total burden of disease (DALY) for Oslo is estimated to be 2674, with particulate matter contributing significantly to premature deaths and severe health problems.
To address these challenges, Norway has implemented measures to reduce air pollution levels. Both national and local authorities have actively worked to improve air quality in cities and towns. This includes focusing on reducing road traffic and wood burning, which are significant contributors to air pollution. Additionally, Norway has introduced air quality criteria and management goals for local air quality, including legally binding limit values and national goals. These efforts aim to protect the health and well-being of Norwegian citizens, particularly those vulnerable to the harmful effects of air pollution.

Air pollution causes health issues
Air pollution is considered the most important environmental factor that causes health effects. In Norway, air pollution is far more prevalent during the cold winter months. This is due to higher emissions from wood-burning, road dust from studded tyre use, and exhaust emissions from cold engines in freezing temperatures. Meteorological inversions also result in poorer dispersal conditions in winter.
Particulate matter (PM2.5 and PM10), nitrogen dioxide, and ozone are the main components of air pollution in Norway. These pollutants are caused by road traffic, wood-burning, and industrial emissions. Exposure to these pollutants can cause respiratory tract issues, such as asthma, COPD, and cardiovascular disease. Vulnerable groups, including those with existing illnesses, pregnant women, children, and the elderly, are at a higher risk of adverse health effects. The Norwegian Institute of Public Health estimates that 185 and 115 deaths annually can be attributed to fine fraction PM2.5 and PM10 pollution.
To address air pollution, Norway has implemented legally binding limit values, air quality criteria, and national goals for local air quality. The limit values in the Pollution Control Regulations ensure a minimum air quality level, while the air quality criteria indicate safe levels for everyone, including vulnerable groups. National goals represent the government's future aspirations for air quality. Efforts to improve air quality in Norway have shown progress, with measurements indicating improved air quality in cities.
While Norway has made strides in managing air pollution, there is a continuing need to acquire knowledge and implement measures to sustain good air quality amidst the country's growing urbanisation. Norway's air pollution levels are similar to other Scandinavian countries but are lower than most other large towns in Europe. The European Environment Agency estimates that approximately 1,700 people in Norway die annually from high levels of PM2.5.
Overall, air pollution in Norway poses health risks, particularly during winter. The country has implemented various strategies to mitigate this issue, resulting in some improvements. However, ongoing efforts are necessary to ensure sustainable urban development and maintain good air quality for the well-being of its citizens.

Particulate matter and nitrogen dioxide are major pollutants
Nitrogen dioxide (NO2) is produced when oxygen and nitrogen in the air react during the combustion of fossil fuels, such as oil, diesel, and gas. Long-distance pollution from other European countries also contributes to elevated NO2 levels in Norway. Both PM and NO2 have been linked to adverse health effects, particularly for vulnerable groups such as children, the elderly, and individuals with respiratory and cardiovascular issues.
To address this issue, Norway has implemented measures to reduce road traffic and wood burning, which are significant contributors to air pollution. These efforts have shown positive results, with a decline in PM levels over the last decade. The Norwegian Institute of Public Health and the Norwegian Environment Agency have set stringent air quality criteria for PM10 and PM2.5 to protect public health.
While Norway's air pollution levels have been relatively stable over the years, seasonal variations exist, with higher pollution levels during the cold winter months due to increased emissions from wood burning, road dust, and exhaust emissions. Meteorological inversions during winter further exacerbate the issue by hindering dispersal conditions. Nonetheless, Norway's air pollution levels remain lower than those of most other large towns in Europe.
The Norwegian government has introduced various initiatives to tackle air pollution, including providing municipalities with tools to manage air quality, such as queue pricing and increased tolls during high air pollution days. Additionally, a nationwide service has been established to provide real-time air quality information and health advice for the general population and vulnerable groups.

Pollution is worse in winter
While Norway is among the European countries with the lowest risk of premature death due to local air pollution, it still faces challenges in this regard. Air pollution is far more prevalent during the cold winter months. This is due to several factors, including higher emissions from wood-burning, road dust from studded tyre use, and exhaust emissions from cold engines in freezing temperatures. In addition, meteorological inversions during the winter result in poorer dispersal conditions, leading to higher pollution levels.
Particulate matter (PM), nitrogen dioxide, and ozone are the primary contributors to local air pollution in Norwegian cities and towns. PM refers to microscopic liquid or solid particles suspended in the air, which can be inhaled and cause respiratory and cardiovascular health issues. PM2.5 and PM10 are the most common types, with PM2.5 being the smallest particles primarily originating from combustion sources such as wood-burning and car exhaust. PM10 particles are larger and come from sources like road dust and tyre wear.
Nitrogen dioxide (NO2) is produced during the combustion of fossil fuels, while ozone (O3) is formed from the reaction of nitrogen oxides, volatile organic compounds, and sunlight. Both have detrimental effects on human health, particularly for vulnerable groups such as children, the elderly, and those with existing respiratory and cardiovascular conditions.
To combat air pollution, Norway has implemented various measures, including legally binding limit values, air quality criteria, and national goals for local air quality. The Norwegian Institute of Public Health plays a crucial role in establishing criteria and guidelines to reduce pollution from traffic and wood-burning. While air pollution levels have remained relatively stable over the last decade, there is a continuous effort to improve air quality and protect the health of Norway's citizens.
In conclusion, while Norway has made strides in managing air pollution, it remains a concern, especially during the winter months. By addressing the sources of pollution and implementing strategies to reduce emissions, Norway can continue to improve air quality and mitigate the health risks associated with pollution, particularly during the winter season.

Traffic and wood-burning contribute to poor air quality
While Norway is among the European countries with the lowest risk of premature death from local air pollution, it still faces challenges with poor air quality, particularly in its cities. Oslo, for instance, is the Nordic capital with the most air pollution, ranking 66th out of 760 cities in a recent report.
Traffic and wood-burning are significant contributors to Norway's air pollution problem. Emissions from road traffic, including exhaust fumes and road dust from studded tyres, are the most important source of nitrogen oxides (NOx) in Norwegian cities. These emissions react with other compounds in the atmosphere to produce ozone, another harmful pollutant. During the cold winter months, emissions from traffic increase due to the use of cold engines in freezing temperatures, and the burning of wood for heat becomes more prevalent, leading to higher levels of air pollution.
Wood-burning and the use of studded tyres for traction during heavy snowfall are cultural practices that impact air quality. While these practices contribute to the comfort and safety of Norwegians, they also release pollutants into the air. For example, wood-burning releases particulate matter (PM), which includes microscopic solid or liquid particles that can be inhaled and cause respiratory issues. Similarly, studded tyres generate road dust, which contributes to the overall concentration of PM in the air.
To address these issues, Norway has implemented various measures to reduce air pollution caused by traffic and wood-burning. These include setting criteria and introducing measures against traffic and wood-burning and providing health and activity advice for vulnerable groups. The Norwegian Meteorological Institute, the Norwegian Public Roads Administration, and other organisations have collaborated to develop a real-time air quality monitoring service, enabling people to adapt their activities based on pollution levels.

Frequently asked questions
Yes, air pollution is a problem in Norway, although the country is among those in Europe with the lowest risk of premature death as a result of local air pollution.
Particulate matter (PM2.5 and PM10) and nitrogen dioxide (NO2) are the major substances that contribute to local air pollution in Norwegian cities and towns. Particulate matter is produced by combustion in engines, stoves, fireplaces, and exhaust emissions, as well as road dust from tyres, asphalt wear, and brake pads. Nitrogen dioxide is produced by the combustion of fossil fuels, such as oil, diesel, and gas.
People exposed to air pollution can become ill, or their existing medical problems can worsen. This primarily affects diseases of the respiratory tract, such as asthma, COPD, and cardiovascular disease. There is also evidence that air pollution can affect the nervous system and cause issues such as diabetes. Children, the elderly, pregnant women, and those who are already ill are particularly vulnerable.
Norway has three different management goals for local air quality: legally binding limit values, air quality criteria, and national goals for local air quality. To reduce air pollution, criteria have been set, and measures have been introduced to reduce road traffic and wood burning. A nationwide service also provides real-time air quality data for Norway, allowing vulnerable groups to receive health and activity advice.
