Relocate factories to other islands
One of the most effective ways to deal with pollution in Anno 1800 is to relocate factories and industrial production to other islands. This strategy not only helps to reduce pollution on your main island but also allows for more efficient resource management and city planning. Here are some detailed instructions and tips for relocating your factories:
Choose the Right Island:
Select an island that is nearby and easily accessible from your main island. This facilitates the transportation of goods and workers between the two islands. Consider the size and resources of the new island to ensure it can accommodate all the necessary factories and infrastructure.
Set Up Transportation:
Construct a Commuter Pier on both your main island and the new industrial island. This building is crucial as it enables the transfer of workforce populations between the islands. You can then use the Stamp tool to transfer factories and production facilities to the new island.
Stepwise Relocation:
Instead of relocating all factories at once, consider a stepwise approach. Start by relocating a specific type of production, such as agricultural or steel production, to the new island. Continue producing raw materials on both islands and bring them to the old island to create a buffer stock. Once you have a stable supply, destroy the old production facilities and establish new processing facilities on the new island. Update your trade routes accordingly.
Create Specialization:
You can create specialized islands dedicated to specific types of production. For example, you can have an island for agriculture and food/drink factories, one for non-food items and materials, or even a beer and schnapps island. This approach streamlines production and can make resource management more efficient.
Manage Raw Materials:
As your city grows, the demand for raw materials will increase. Consider the mining potential of your industrial island(s) and whether you need to dedicate trade unions to buff mines. Alternatively, invest in items and electricity to boost production or reduce the needed input.
Plan for High Population:
When playing with a high population, be prepared to adapt your strategy. You may need to relocate your production multiple times to larger islands or split production across multiple islands. Focus on creating islands with high-density housing and production, providing your workforce with the necessary lifestyle goods.
By following these steps and tips, you can successfully relocate your factories to other islands, reducing pollution on your main island and creating a more efficient and attractive city in Anno 1800.

Improve city attractiveness
City Attractiveness in Anno 1800 is defined by six factors: culture, nature, festivity, vulgarity, pollution, and instability.
To improve city attractiveness, you can focus on the positive factors: culture, nature, and festivity, while reducing the negative effects of pollution and vulgarity.
Culture
Bring new species of animals and exotic artifacts from your expeditions to increase the culture factor. You can also construct objects of interest, such as ornaments, a zoo, or a museum, to attract visitors and increase city attractiveness.
Nature
Ensure that your city is covered with greenery and natural monuments. Free space, untouched forests, and meadows create scenic beauty, enhancing the nature factor.
Festivity
Gain majority support from your society by taking care of your dwellers' needs and constructing community buildings. This will encourage your settlers to organize parades and festivals, increasing the festivity factor.
Pollution
To deal with pollution, consider the following strategies:
- Delocate polluting production chains to another island, specifically one with low fertility or limited space, to reduce the impact on your main island.
- Utilize items that decrease pollution within trade unions, such as the Bumm Brimmell item from the Land of Lions DLC, which provides +20 attractiveness for every Bootmaker.
- Spread out your factories across multiple islands to minimize the concentration of pollution in one area.
- Establish specific production islands for certain industries, such as a beer island or a canned food island, to isolate pollution.
Vulgarity
Avoid building multiple military facilities or leaving ruins of destroyed objects, as these will negatively impact city attractiveness.
By implementing these strategies, you can improve city attractiveness in Anno 1800 while also dealing with pollution.

Focus on nature and culture
In Anno 1800, there is a new system called City Attractiveness, which rewards players for building beautiful and attractive cities. The higher the attractiveness of your island, the more tourists will arrive and the more money they will spend.
Nature and festivity are two of the three positive factors that contribute to the City Attractiveness rating. To increase the nature rating, players can focus on maintaining free space on their island, such as untouched forests and meadows, which create a scenic view.
To increase the attractiveness of your island without reducing pollution, you can obtain certain items that increase attractiveness and place them in Trade Unions, Town Halls, or Harbourmaster's Offices. For example, players can obtain the Bumm Brimmell trade union item, which gives +20 attractiveness for every Bootmaker.
However, it is important to note that these methods only cancel the negative effects of pollution and do not actually reduce pollution levels. To effectively deal with pollution, players are advised to relocate polluting production chains to another island, known as a "dirty kitchen" island, and then ship the goods back to the main island.

Use items to decrease pollution
To decrease pollution in Anno 1800, players can use specific items and strategies. One effective approach is to relocate factories and industrial buildings to nearby islands, reducing pollution levels on the main island. This strategy, known as "offloading" or creating "dumpster islands", helps maintain the attractiveness of the main island, attracting tourists and increasing revenue.
To facilitate this strategy, players can utilise the Commuter Pier building, which allows for the transfer of workforce populations between islands. By selecting an island that can accommodate the required factories and is nearby for easy transportation, players can effectively manage pollution.
Additionally, players can obtain specific items from trade unions to decrease pollution. For example, the "Bumm Brimmell" trade union item, available with the Land of Lions DLC, provides +20 attractiveness for every Bootmaker, contributing to positive "pollution attractiveness." Players can also focus on improving city attractiveness through culture, nature, and festivity, as pollution is a significant detractor in this regard.
Another strategy to reduce pollution is to make use of the Docklands Main Wharf building, which reduces the need for factories by allowing the purchase of industrial goods. Players can also increase city attractiveness by introducing new species of animals, exotic artifacts, and constructing community buildings to enhance festivity and the happiness of dwellers.

Avoid wars and conflicts
Avoiding wars and conflicts in Anno 1800 can be crucial to maintaining a prosperous and stable city. Here are some strategies to avoid wars and maintain peaceful relations:
Diplomacy and Ceasefires
Ceasefires can be arranged with enemy factions, even if relations are strained. Negotiating a ceasefire usually involves a small monetary cost, and it can help improve your reputation with the enemy faction. Chaining multiple ceasefires together is an effective way to avoid combat and lay the groundwork for a future peace treaty.
Maintain Good Relations
Building and maintaining positive relationships with AI factions early in the game can help prevent them from declaring war. Expert AIs are more likely to initiate wars, while Normal and Easy AIs are less inclined to do so. A Non-Aggression Treaty with a faction prevents both parties from declaring war on each other.
Avoid Alliances
Alliances with AI factions can sometimes lead to unintended wars. If you are unprepared for a full-scale war, it is advisable to avoid alliances, as they can complicate your situation and lead to unwanted conflicts.
Manage Reputation
If your reputation with an AI faction is low, work on improving it. You can use flattery and money to slowly build your reputation. Once your reputation reaches a certain threshold (around 30-45), you may be able to propose a peace treaty. However, be prepared to pay a substantial sum to the AI faction to secure the treaty.
Strengthen Military
While avoiding wars is ideal, sometimes a strong military presence can act as a deterrent. If your military might is significantly greater than that of a hostile faction, they may be less inclined to declare war. Ensure your navy is well-positioned and composed of ship types suited to your strategic needs.
By employing these strategies, you can focus on managing your city's pollution levels without the added challenge of ongoing wars and conflicts.
