“A left climate politics must move beyond a language of cost-internalization, and emphasize the real material benefits for a society beyond fossil fuel: not only in terms of a cleaner environment, but also cheaper energy and green jobs. This requires a language of public goods and collective action, not a language of markets and costs. If the Left must speak of costs at all, it needs to be framed in class terms — costs that the wealthy and corporations must pay to fund a better energy economy.”
