Strategies To Reduce Air Pollution In Simcity 4

Air pollution is a common issue in SimCity 4, caused by dirty industries, manufacturing industries, power plants, traffic, and airports. It lowers the land value, makes it difficult for Sims to breathe, and causes illnesses, lowering the happiness of both industrial and commercial zones. While there is no single solution to eliminating air pollution, several strategies can help mitigate it. These include the use of public transportation, enacting pollution-reducing ordinances, and carefully placing polluting industries and structures. Additionally, natural elements like trees and parks can help absorb and reduce air pollution, but they have limitations and can be expensive. Players must also consider the education level of their Sims, as higher education encourages the development of high-tech industries, which are less polluting.

Use of trees and parks to reduce air pollution

Trees and parks can play a significant role in reducing air pollution in SimCity 4 and in real life. In the game, players can strategically place trees and parks to mitigate air pollution caused by dirty industries, manufacturing industries, power plants, airports, and traffic. Similarly, in real life, urban forests and green spaces have been shown to effectively reduce air pollution and improve air quality in cities.

Trees are known for their ability to directly remove pollutants from the air. They achieve this through the absorption of gaseous molecules and the interception of particulate matter. The leaves of trees are covered in tiny pores called stomata, which allow trees to absorb air, including toxic pollutants. Once inside the leaf, the gases are converted, effectively removing them from the air. Trees can also temporarily catch particulate matter, reducing the amount of harmful pollutants in the air.

Urban forests and parks contribute to improved air quality by removing multiple tons of ozone, gaseous air pollution, and particulate matter each year. According to the U.S. National Park Service, the trees in their urban forests have led to a net reduction in urban ozone formation. Studies have calculated that certain parks can remove over 1.1 million metric tons of air pollution annually, including pollutants like ozone, sulfur dioxide, nitrogen dioxide, carbon monoxide, and fine particulate matter.

In addition to their direct impact on air pollution, trees also provide indirect benefits. They can reduce air temperature, lower energy consumption in buildings, and decrease the need for conventional air conditioning, which in turn reduces greenhouse gas emissions. Trees also play a vital role in ecosystems by absorbing carbon dioxide and emitting oxygen, improving the air quality for humans and other living beings.

While trees and parks can effectively reduce air pollution, it is important to note that not all trees are equally effective. The effectiveness of trees in reducing air pollution depends on the specific species and the local environmental context. For example, while maple trees are known for their ability to trap air pollution particles, yew trees may not be suitable for certain locations due to their poisonous nature. Therefore, a holistic understanding of urban ecosystems is necessary to maximize the benefits of tree-planting initiatives.

Move polluting industries and power plants to a different city

If you want to transition to a high-tech industry and get rid of polluting industries and power plants, you can do so by starting a new small neighbouring city and filling it with heavy industry tiles. Each city in SimCity is wrapped in an airtight bubble that doesn't allow pollution to waft over from city to city.

To get rid of polluting industries, you can slowly increase taxes to 13% to slow down and stop growth, then to 18-20% when you're ready to get rid of them entirely. However, it is important to note that your city must have sufficient demand for high-tech industries to replace the tax revenue from polluting industries. Hi-tech demand is strongly dependent on education, so make sure the education level and the RCI indices for Hi-tech are high.

While transitioning, you can also try to control the spread of pollution by using trees and parks. The Pollution Ordinance (Clean Air Act) will also reduce the overall amount of pollution emitted by each building. As your Sims become more educated, I-M and later I-HT should replace I-D buildings. However, both, especially I-HT, desire unpolluted areas and will abandon polluted areas.

Additionally, you can use the Industrial Revolution Mod, which changes Ind zoning so that low-density zones grow only I-D and polluting I-M, while high-density zones grow only low-polluting I-M and I-HT. This gives you more control as a player and prevents I-HT abandonment.

Enact pollution-reducing ordinances like the Clean Air Act

To reduce air pollution in SimCity 4, players can enact pollution-reducing ordinances like the Clean Air Act. This in-game ordinance functions similarly to its real-world counterpart, the Clean Air Act of 1970, which led to a significant reduction in pollution and brought about various social and economic benefits.

The Clean Air Act ordinance in SimCity 4 will reduce the overall amount of pollution emitted by each building. This is particularly important when dealing with dirty industry buildings, which produce high levels of air pollution. By enacting this ordinance, players can take a proactive step towards improving the air quality in their simulated cities.

Additionally, players can complement the Clean Air Act with other in-game ordinances that combat pollution. For example, the carpool incentive program targets car emissions, a significant contributor to air pollution. By incentivizing carpooling, players can reduce the number of vehicles on the road and, consequently, decrease traffic-related air pollution.

It is worth noting that while these ordinances are effective tools, they do not provide a complete solution to the pollution problem in SimCity 4. Players should also consider other strategies, such as strategically placing polluting industries in corners or near natural barriers like mountains to contain pollution spread. Additionally, investing in parks and planting trees can help absorb and reduce air pollution, creating a healthier and more aesthetically pleasing environment for your simulated citizens.

By enacting the Clean Air Act and other pollution-reducing ordinances, players can make a substantial difference in managing air pollution in SimCity 4. These measures not only enhance the gameplay experience but also reflect the real-world importance of environmental regulations in improving the quality of life for individuals and communities.

Reduce traffic congestion and provide more public transportation

Traffic congestion in SimCity 4 can be mitigated by installing the Network Addon Mod (NAM). This mod encourages Sims to take the fastest route to their destination, rather than always using the same route, even if it is overused. NAM also provides more transport options, such as subways and highways to the same location. Decentralising your zones can also help to reduce congestion, especially when used in conjunction with NAM.

To reduce car usage, it is important to provide realistic zoning practices. Ensure that residential zones are not separated from job zones, as commute time has a large impact on desirability and development. Commercial areas can benefit from high traffic, so routing traffic through these areas can be beneficial.

Public transportation in SimCity 4 is represented by mass transit. Unlike cars, mass transit trips do not have the 24-second overhead that is meant to cover the time it takes for Sims to walk out of their house, get in their car, and so on. This helps to equalise the advantage that cars have over mass transit.

While public transportation in SimCity 4 is inexpensive and convenient, it is not faster than a car. This is realistic, as the player must factor in walking and waiting times, which can make public transportation much slower than a car.

Use of the Industrial Revolution Mod to control the types of industries in different zones

The Industrial Revolution Mod is a useful tool for controlling the types of industries in different zones in SimCity 4. This mod allows players to specifically zone high-tech and dirty industries, which was not possible in the vanilla game.

With this mod, low-density zones will only grow dirty industry (I-D) and polluting manufacturing industry (I-M), while high-density zones will only grow low-polluting manufacturing industry (I-M) and high-tech industry (I-HT). This change gives players more control over their cities and helps prevent the abandonment of high-tech industries due to pollution.

To utilise this mod effectively, players can confine pollution to specific locations by placing polluting industries at the city's corners or enclosing industrial zones behind mountain ranges. Additionally, the negative effects of air pollution can be mitigated by planting trees and building parks, and the Clean Air Act ordinance can be enacted to reduce overall pollution levels.

While the Industrial Revolution Mod can enhance gameplay, it is important to note that it has not been updated since 2017 and may require a significant amount of time to install due to its long list of dependencies. Players may need to start a new game or destroy existing industries in their regions to use the mod effectively.
