How is the environmental governance applies to climate change?

In my manual, I discuss the definition of environmental governance, key players/actors, its framework, its principles, and its application. One of the applications that I looked at is the watershed. Another one that I want to look at is the climate change and the type of framework that is used. The material I wanted to use was more complicated than I expected. If there is something simple and typical, I would appreciate any help with a list of references.
