Place industrial zones away from residential areas
When playing Cities: Skylines, it's important to consider the placement of your industrial zones in relation to your residential areas. Here are some reasons why you should place industrial zones away from residential zones and some strategies for doing so effectively:
Impact of Industrial Zones on Residential Areas
Industrial zones in Cities: Skylines are a significant source of pollution, including air, ground, and noise pollution. Air pollution is caused by industry, traffic, garbage management, and specific power plants. Ground pollution is mainly generated by industry, power plants, and garbage management facilities and can contaminate groundwater and resources such as forests and fertile land. Noise pollution, which is inevitable, can annoy and sicken citizens, affecting their happiness and health.
Strategies for Placing Industrial Zones Away from Residential Areas
- Distance and Buffer Zones: While distance alone may not be a solution, as wind direction plays a crucial role in the spread of pollution, creating a buffer zone between industrial and residential areas can help. Commercial zones, which are unaffected by pollution, can be placed between industrial and residential zones. Similarly, office zones can be used as a buffer for noise pollution, especially for high-density residential areas.
- Specialized Industries: Once you reach the Worthy Village milestone, you can create districts with specialized industries. Farming and forestry do not cause pollution, so you can meet the demand for industry zoning while preserving the environment. However, some farming and forest buildings in the Industries DLC do produce pollution.
- Upgrading Industrial Buildings: Regular industrial buildings can be upgraded, and these upgraded versions tend to produce less pollution than level one buildings.
- Water Management: Proper water management is essential. Ensure that sewage is placed downstream, away from water pumping stations, to prevent citizens from getting sick. Investing in sewage upgrades is crucial as your city expands.
- Traffic Management: Traffic is a significant issue in the game. Keeping high-density and low-density residential areas separate, except for highways, can help prevent traffic problems. Additionally, implementing district policies such as combustion engine bans, heavy traffic bans, and installing speed bumps can reduce traffic and noise pollution.

Manage traffic flow and use electric buses
Managing traffic flow and reducing pollution caused by vehicles are important aspects of maintaining a thriving city in Cities: Skylines. While cars do not create air pollution in the game, electric buses can help reduce noise pollution, making them more suitable for residential areas. Additionally, switching to electric buses and implementing district policies such as combustion engine bans, heavy traffic bans, and speed bumps can effectively reduce air and noise pollution.
To manage traffic flow, players can utilize the Traffic Flow heatmap, accessible from the left-hand menu. This tool highlights areas with moderate (yellow) and heavy (red) traffic, allowing players to identify problem areas and implement solutions. One strategy is to build slip roads to divert traffic and ease congestion on main roads. Roundabouts at highway exits can also help distribute traffic more evenly.
Another approach to managing traffic is through the use of public transportation. By encouraging the use of electric buses and other efficient modes of transportation, players can reduce the number of private vehicles on the roads. This not only helps alleviate traffic congestion but also contributes to reducing air pollution.
While the game offers mods that provide additional traffic management options, such as changing traffic rules and creating restricted roads, they are not necessary for effective traffic management. Players can implement strategies such as placing industrial zones away from residential areas and utilizing sewage upgrades to minimize the impact of pollution on their citizens' health and happiness.
Overall, managing traffic flow and using electric buses are crucial components of maintaining a healthy and happy city in Cities: Skylines. By reducing congestion and transitioning to cleaner modes of transportation, players can create a more sustainable and enjoyable environment for their citizens.

Use renewable energy sources
In Cities: Skylines, pollution is a major aspect of the game that players must manage. Poor placement of services that output pollution can be detrimental to your city. Air pollution is caused by industry, traffic, garbage management, and specific power plants. Ground pollution is more challenging to deal with due to its lasting impact on your city's land, and it takes a long time for the pollution to disappear entirely.
To reduce pollution, players can implement policies and make thoughtful building choices. For example, players should place industrial zones away from residential zones, and ensure that sewage output is placed downstream from the city's water pumping stations.
Renewable energy sources play a crucial role in reducing pollution and creating a positive image for your city. While they may be more expensive to implement, they are the best option in the long run. Here are some ways to utilize renewable energy sources in Cities: Skylines:
- Wind Power: Wind turbines are a popular choice for renewable energy in the game. They are easy to scale by placing more turbines, and they can be aesthetically pleasing, especially on maps with mountains. Players can unlock the "Green Energy" achievement by building a windmill at the start of the game.
- Solar Power: Solar power plants, including Solar Updraft Towers, are another option for generating renewable energy.
- Geothermal Power: Geothermal power plants are also mentioned as a source of renewable energy in the game.
- Ocean Thermal Energy Conversion: This type of power plant is included in the list of buildings that can unlock the "Green Energy" achievement.
By transitioning to renewable energy sources and implementing other policies, players can minimize pollution and keep their citizens happy and healthy.

Place sewage pumps downstream
In Cities: Skylines, pollution is an important aspect of the gameplay that can affect the happiness and health of your citizens. While it is impossible to completely avoid pollution without using DLC buildings or special mods, implementing the right policies and building choices can keep pollution to a minimum.
One crucial aspect of managing pollution is understanding the water and sewage systems in the game. Water pumping stations and water towers are used to draw water from rivers and wells, while water drain pipes and water treatment plants are used to dispose of sewage. However, even after upgrading to treatment plants, sewage water remains polluted. Therefore, it is essential to place the output buildings downstream from the pumps to prevent the pollution of the city's water supply.
To effectively manage sewage and pollution, it is recommended to place sewage pumps downstream, preferably close to your city's border. This ensures that the sewage is carried away from the population centers and reduces the risk of water contamination. By placing sewage pumps downstream, you can minimize the impact of pollution on your city and maintain the health and well-being of your citizens.
Additionally, it is important to keep water pumping stations upstream and away from any pollutants entering your water system. Regularly monitoring the water info view and ensuring that both "Water Availability" and "Sewage Treatment" are in the green zone is crucial. If they start to enter the yellow zone, consider boosting the budget or adding more pipes and drains to accommodate the demand.
While managing sewage and pollution, it is also essential to consider the wind direction. Air pollution spreads in the direction of the wind, so utilizing the Air Pollution Info View can help you strategically place your industrial zones to minimize the impact on residential areas. By combining strategic placement of sewage pumps and industrial zones with effective water and sewage management, you can significantly reduce pollution levels in your city and create a healthier environment for your citizens in Cities: Skylines.
