Or we could tax carbon and internalized the negative externality. If you think that without capitalism we suddenly would take care of the environment, compare the destruction of the environment in communist countries to capitalist ones. Soviet Russia had a "nuclear lake" they just dumped nuclear waste into, Bitterfeld in the GDR was known for having it's creeks discolored from the chemicals dumped into them, the amount of smoke coming out of old, massive rural Chinese factories is hard to imagine if you haven't seen it; The Trabant spewed out orders of magnitude more exhausted than any western car. The problem isn't capitalism, but resource constraints.
