States are really important when it comes to taking care of our environment around the world. Here are some ways they do this:

1. International Agreements:

   • More than 190 countries have agreed on the Paris Agreement. This is a promise to try to keep global warming below 2 degrees Celsius.
   • The Kyoto Protocol is another agreement that 191 countries signed. It aimed to cut greenhouse gas emissions by 5.2% compared to levels from 1990.

2. Regulatory Frameworks:

   • States create rules like carbon pricing. Right now, over 60 regions have carbon markets. These cover about 22% of the world's emissions.

3. Funding and Support:

   • Wealthy countries have promised to give $100 billion every year by 2020. This money is for helping poorer countries deal with climate change.

4. Collaboration:

   • Programs like the United Nations Environment Programme (UNEP) help countries work together to protect the environment.

By working together, states can make a big difference in keeping our planet safe and healthy!
