DE temporarily cuts gasoline & diesel taxes: -expensive -not really progressive -mutes oil-saving incentives -encourages other countries to do the same -resulting lack of demand response leads to higher oil prices Why are more sophisticated solutions deemed infeasible, politically/administratively?

Climate politics sounds increasingly polarised. But in Europe, support for climate isn’t driven by die-hard supporters or opponents. It tends to be shaped by a large “conditional middle” (33%).

Most of these damages come from non-market values: nutrition, coastal protection, and the existence value of marine ecosystems — not just market losses.

1. In a GREAT paper (why isn't it published??), Anthoff, Dennig & @johannesemm.bsky.social show that most IAMs have a hidden goal of a uniform price and define Negishi weights to arrive at that goal. Yet, carbon price should grow at the discount rate (at least under a carbon budget constraint)...
