What is the relationship between global environmental governance and environmental governance?

During the course of my research on environmental governance, I came across another term, global environmental governance. Even though I can find its definition, I was wondering how both terms, global environmental governance and environmental governance are related? Is global environmental governance a branch of environmental governance? Or is global environmental governance a global regulatory arm of environmental governance? or Is global environmental governance a collection of many environmental governance? I simply want to briefly mention the definition of global environmental governance and its relationship to environmental governance. Are the concept of global environmental governance and environmental governance very similar? If not, I could briefly describe its concept? Nothing complicated. Thanks for help.
