In the eco-friendly game Carbon Island, obtaining experience points is extremely difficult. We all know that experience points determine our level, and the more experience points we have, the faster our character levels up. However, due to the difficulty of acquiring experience points in Carbon Island, many players' levels progress very slowly. In this article, I will share some methods for quickly leveling up in Carbon Island.

As a manager of the island, if players want to gain experience and level up quickly, there are 5 methods in total.
1. Complete the rating conditions
Each time a player completes a rating in the game, they can earn a large amount of experience points. To complete the rating, players need to find the trophy icon on the main page, which is located at the bottom right corner. Open the trophy, and there will be an option for promotion evaluation. First, check the rating requirements, understand them, and then complete each requirement one by one. After that, click the upgrade option, and follow the system prompts to complete the rating.

2. Build and upgrade infrastructure
In the game, the island has just suffered from a natural disaster, and most of the infrastructure has been destroyed. Each time a player builds a set of infrastructure, they can earn a specified amount of experience points. The infrastructure includes power plants, residential buildings, hospitals, factories, and docks. After all the infrastructure is built, you can continue to earn experience points by upgrading it.
3. Invest in research and development
When the island's economy starts to recover, players can also earn experience points again by investing in technological research and development or upgrading buildings. For example, you can upgrade the coal-fired power plant on the island, which will then become a gas power station or a nuclear power plant. After the upgrade is completed, you will receive an experience point reward from the system.

4. Plant greenery
The construction of the island cannot do without ecological construction, and planting greenery is one of the most direct methods of ecological construction. By following the requirements and planting the specified number of green plants, you can naturally obtain experience points.
5. Renovate polluted areas
The polluted areas in the game constantly affect the city's greening, making renovation necessary. Once the renovation is successful, you will also receive corresponding experience points.

In summary, there are many ways to obtain experience points in Carbon Island. As long as you complete all these methods, you will earn a large amount of experience points, which can also quickly increase your level.
