Sweden has been really important in helping the European Union (EU) make rules about climate change. Here are some of the main things Sweden is doing:

1. Setting Big Goals: Sweden wants to cut its greenhouse gas emissions to zero by 2045. This goal matches what the EU is trying to achieve. By 2021, Sweden had already lowered its emissions by 30% since 1990.

2. Investing in Clean Energy: In 2020, Sweden got about 55% of its energy from renewable sources, like wind and solar power. This is a big help for the EU's goal of getting 32% of energy from renewables by 2030.

3. Supporting Strong Climate Laws: Sweden has worked hard to get stricter climate rules in the EU. One of these rules is called the European Green Deal, which aims to make the EU climate-neutral by 2050.

4. Giving Financial Help: Sweden spends about €1 billion every year on global climate projects. This shows how important funding is for climate policies.

Through all these efforts, Sweden continues to lead the way in promoting strong plans to fight climate change in the EU.
