What You'll Learn
Ground pollution
In the game Cities Skylines, pollution is a negative effect that can cause sickness, death, and abandonment. There are four types of pollution: air, ground, water, and noise. Ground pollution is generated through industrial buildings and other buildings that produce unhealthy atmospheric conditions. Factories, power plants, incinerators, and garbage dumps are all sources of ground pollution.
While it is challenging to eliminate ground pollution entirely in the game, players can take several measures to reduce it. One strategy is to spread out industrial zones and leave ample space between them. This approach can help transform industries into high-tech zones, reducing pollution significantly. Additionally, players can construct the Eden Project monument, which prevents the spread of ground pollution to neighbouring buildings.
Another way to minimise ground pollution is to prioritise green energy sources over coal and gas power plants. Wind turbines, available from the start of the game, are an excellent choice for cleaner energy production. Players can also use the "district tool" to ban heavy traffic and combustion engines from residential areas, reducing ground pollution caused by vehicles.
It is worth noting that ground pollution dissipates over time if the source is removed. Therefore, players can choose to de-zone polluted areas and wait for the pollution to vanish before re-zoning the area. However, this process may take considerable time, and players must exercise patience.
To monitor ground pollution levels, players can utilise the "info view" feature in the game. This view provides information on all pollution types, allowing players to assess the impact on their city and make informed decisions to mitigate ground pollution.

Water pollution
To address water pollution in Cities: Skylines, there are several strategies you can employ. Firstly, ensure that your Water Towers and Pumps are not placed near polluted areas. Move them away from any sources of pollution, be it ground or water pollution. This will help prevent the contamination of your water supply.
Next, set up Water Pumping Stations upstream and Water Draining Pipes or Water Treatment Plants downstream. Make sure to connect these with water pipes, ensuring that the pipes run underneath every structure so that your citizens have access to water and can dispose of sewage effectively. Additionally, consider the direction of water flow. Avoid placing pumps in areas with weak water flow, as they may pull pollution towards them.
If your water body is already polluted, you can speed up the cleaning process. Place pumps to suck up the dirty water and connect them to outlet pipes. This will allow you to remove the polluted water and replace it with clean water. Alternatively, you can simply wait for the fresh water to push the dirty water downstream naturally.
It is important to note that upgrading to better water sewage treatment plants will help reduce the amount of pollution in your water supply. Additionally, try to keep your industrial zones and power plants away from residential areas to minimise the impact of pollution on your citizens.

Noise pollution
In Cities: Skylines, noise pollution is a common problem that players must manage. Noise pollution is caused by loud frequencies from various sources, such as wind turbines, traffic, airports, and areas with high sound levels. It is represented by an icon with headphones, and clicking on it will display the noise pollution levels across your city.
To view the pollution tab and manage noise pollution, follow these steps:
- Click on the informational panel in the upper left-hand corner of the screen.
- This will open a panel with various icons, including the noise pollution icon (headphones).
- Click on the noise pollution icon to access the pollution tab.
- The tab will show both the emitters of noise pollution and the areas most impacted by it.
Once you have identified the noise pollution sources and affected areas, you can implement strategies to reduce noise pollution levels. Here are some strategies to consider:
- Planting trees: Trees placed alongside roads and highways can help reduce noise pollution. Consider using a tree 'paintbrush' mod to cover large areas efficiently.
- Sound barriers: Construct sound barriers along highways and roads to mitigate vehicle noise.
- Zone planning: Avoid placing noisy buildings, such as industrial and commercial structures, near residential areas. Try to maintain a distance between the noise sources and residential zones.
- Electric vehicles: Encourage the use of electric cars, which tend to be quieter than other vehicles. Policies favoring electric cars or restricting large vehicles can help reduce traffic noise.
- Office areas: Place office areas instead of industrial zones to reduce noise pollution while maintaining economic activity.
- Green energy: Opt for green energy sources, such as wind turbines, over coal and gas power plants.
- Downwind placement: If industrial zones are necessary, place them as far downwind as possible, preferably near the border of the map.
- Health and leisure facilities: Adding more hospitals, public pools, and health buildings can help citizens stay healthy despite noise pollution.
- Unique buildings: Some unique buildings, like the Eden Project, can reduce or eliminate certain types of pollution.

Air pollution
In Cities: Skylines 2, air pollution is a pressing issue that can negatively impact the happiness and health of your citizens. It is caused by a combination of factors, including industry, traffic, garbage management, and specific power plants. Poor management and placement of these facilities can lead to decreased life satisfaction and even death among your citizens due to poor air quality.
To effectively address air pollution, it is crucial to consider the wind direction. By clicking on the "i" symbol in the top left corner of your screen, you can access the Air Pollution Info View, which displays small arrows indicating wind direction. This information is vital as it determines the direction in which pollution will spread. As a result, it is recommended to place industrial zones downwind from residential areas to mitigate the risk of air pollution spreading to where your citizens live.
Additionally, ensuring smooth traffic flow with minimal traffic jams can significantly reduce vehicle emissions and improve air quality. This can be achieved through careful planning and thoughtful design of your road network. Implementing district policies such as combustion engine bans, heavy traffic bans, and speed bumps can also reduce air pollution and noise pollution. Encouraging the use of public transportation is another effective strategy to reduce the number of vehicles on the road.
While it is challenging to completely eliminate air pollution, you can take several measures to reduce its impact. These include choosing green energy sources, such as wind turbines, over coal and gas power plants, and transitioning to electric buses. As your city grows, you can also assign more commercial and office zones instead of industrial zones, but this requires a large population and a developed economy.
By carefully managing the sources of air pollution and implementing strategic measures, you can significantly improve the air quality in your city and ensure the well-being of your citizens in Cities: Skylines 2.

How to reduce pollution
In Cities: Skylines, pollution is a significant concern, as it can cause sickness, death, abandonment, and a decrease in property values. While it is challenging to completely eliminate pollution, implementing specific strategies can effectively reduce it. Here are some detailed instructions on how to reduce pollution in your city:
Understanding Pollution Types and Sources:
Firstly, it's essential to understand the different types of pollution in the game: air, ground, water, and noise pollution. Air pollution arises from industries, traffic, specific power plants, and garbage management. Ground pollution is mainly generated by industries, power plants, and garbage management facilities. Water pollution is caused by sewage and improperly placed water pumps. Noise pollution, on the other hand, comes from commercial and industrial buildings, roads, service buildings, and monuments.
Reducing Air Pollution:
To reduce air pollution, pay attention to wind direction by using the Air Pollution Info View. Ensure good traffic flow and minimize traffic jams. Choose renewable and cleaner energy sources, such as wind turbines, solar power plants, or nuclear power plants, instead of coal and gas power plants. Use the "district tool" to ban heavy traffic and combustion engines from residential areas.
Reducing Ground Pollution:
Ground pollution is challenging to prevent, especially when starting your city. Opt for cleaner and renewable energy services and facilities. While costly, nuclear power plants, wind turbines, solar power plants, and wastewater treatment plants can help minimize ground pollution.
Reducing Water Pollution:
To minimize water pollution, ensure that sewage is placed downstream, close to your border, and that water pumping stations are placed upstream, away from pollutants. Use water drain pipes and water treatment plants to reduce pollution levels before dumping treated sewage downstream from your city's water pumping stations.
Reducing Noise Pollution:
Keep noise pollution sources, such as commercial and industrial buildings, away from residential areas to prevent sickness and maintain land value.
City Planning Strategies:
When planning your city, place industrial zones and power plants away from residential areas. Check building descriptions before placement to understand their pollution output. Draw districts around industrial zones and specialize in farming or forestry, which produce less pollution. As your city grows, transition from industrial zones to more commercial and office zones.
By following these strategies and making thoughtful decisions, you can effectively reduce pollution in Cities: Skylines and create a healthier and happier environment for your citizens.
