Climate change is clearly a pressing concern for the majority of working-class people. But with 71% of greenhouse gas emissions coming from 100 corporations, capitalism presents a fundamental barrier to solving the problem. After all, you can't control what you don't own.
Under capitalism, production is unplanned, driven by the demands of profit. Only on the basis of public ownership of the major monopolies, with democratic workers' control and management, would it be possible to begin the work of tackling climate change.
