Climate change must be stopped. But who will do the stopping? Who, in other words, could be the political subject of an anticapitalist climate revolution?

I am convinced this social agent could be, and indeed must be, the global working class. Yet to play this role, the working class must develop an emancipatory ecological class consciousness.

Fortunately, history is rife with examples of this kind of green-red synthesis — labor environmentalism is as old as the trade union movement.
