Economic Environmentalism is a school of Environmentalism that specifically uses economic forces to achieve its goals of protecting climate and nature.
It differs from 
other ideologies that may seem similar 
in that it doesn't use only one economic system that "works well" with environmentalism, but is completely opportunist and only focused on what helps its environmental cause. When it uses Socialism, it doesn't do it for the well-being of the workers. When it uses capitalism, it doesn't do it for economic freedom. All it does is for the environment, and the environment only.
