European Union Emissions Trading System

The European Union (EU) Emissions Trading System is like a game where countries in the EU try to have less pollution. Pollution is bad for the planet because it makes the air dirty and the weather change. The game has rules that say how much pollution each country can make.

Each country gets a certain amount of "points" that lets them pollute a certain amount. If a country does not pollute as much as their points allow, they can sell their extra points to another country that needs more points to pollute more.

The goal of the game is for all the countries to work together to have less pollution. If a country pollutes too much, they get in trouble and might lose their points, which means they can't pollute as much anymore.

The EU Emissions Trading System is important because it helps make the planet healthier by reducing pollution. It encourages businesses and industries to find new and better ways to make things without polluting the air as much.
