Especially a carbon market still invites for strong resistance (although this is perhaps less the case if you call it “cap-and-trade”). I used to be pro carbon tax, then indifferent, and now firmly pro carbon market – for the five reasons listed below.

Carbon pricing still meets resistance. But if you consider the cold arguments and evidence, it is the best performing instrument on all key criteria. The table below illustrates this. It merits to be basic knowledge of everyone participating in debates and decisions regarding climate policy.

There is wide agreement that carbon pricing is the key instrument in a climate-policy mix. I agree, but for several reasons that tend to be ignored, even though these may help to convince skeptics. Below I list both classic and additional reasons.

Just changed our Tesla microwave for a Bluesky!

An agrowth worldview comes down to removing the constraint of “always/unconditional growth” (= growthmania). This in turn enlarges the search space for societal progress. In this way we can garner more support for ambitious climate policy.

This third option is "agrowth", which means ignoring GDP and its growth. This is not “ideo-logical” but logical: since GDP is not a good proxy of welfare we better ignore it. This automatically implies indifference/disinterest in GDP growth. Results in being anti-growthmania instead of anti-growth.

I like to post messages about design of climate policy to assure a systemic approach (which limits rebound).

In my ERC project CLIMGROW, an 8-person team studies coevolution of policy design & political support, including the role of "growth opinions"- based on modelling, surveys & experiments.
