There is passionate opposition in some circles to combining “social engineering” with fighting climate chaos. But the fact is, an emissions cut is social engineering. To cut emissions, we are trying to make some of the biggest changes in individual and social behavior ever. Putting 100 percent of that change on the backs of ordinary people by giving away emissions permits that are then sold and incorporated into the prices of consumer goods is also social engineering — social engineering that transfers income and wealth from ordinary people to the wealthy.
