As we wrote: "a limited reliance on carbon pricing provides a disproportionately large share of the benefits offered by theoretically optimal carbon pricing."

What our research showed is that there is a range of policy mixes that are near-optimal. This is because the efficiency advantage of carbon pricing has diminishing returns, which is the main fundamental insight from the paper.

This is not meant to let nations off the hook. The proposal being discussed in Italy is highly ill-conceived. But the point is that climate policy can overcome political challenges by changing how much it relies on different instruments within the policy mix.

As EU lawmakers are looking to soften the continent's CO2 price, it's worth remembering that policy makers can overcome political constraints by complementing CO2 pricing with subsidies without sacrificing much economic efficiency, as I and @knittelmit.bsky.social show here: doi.org/10.1016/j.en...

It’s definitely harder, don’t get me wrong.

There’s a lot to say but to start it makes uncertainty/ignorance explicit. The process itself helps forecasting improve over time. And you can track accuracy with Brier scoring, etc.

In other words, Trump’s mandate is not what he and some others think it is. It is in fact much, much narrower. Also, he is failing it.

Opinion | The Great Capitulation Is Over. What Will Take Its Place?

Reason for hope:

β€œThe 2024 elections weren’t a tectonic social and cultural shift. They were not about rejecting the Enlightenment; they were a complaint about the cost of ground beef. Voters were not embracing patriarchal dictatorshipβ€œ.

An important and underappreciated fact of electricity economics: The US average *wholesale* electricity price is ~5 c/kWh, or ~25% of the average *retail* price of ~19 c/kWh. The other ~75% of the electricity prices we pay is about poles, wires, transformers, generation capacity, and utility profit.

British wind farms drive down day-ahead wholesale energy prices by almost a third in 2025 British wind farms helped limit the role of gas power plants in setting prices, cutting power prices by almost a third, according to new analysis.

β€˜Great Britain’s day-ahead wholesale prices in 2024 could have been up to 33 per cent higher had there been no large-scale wind capacity…around Β£83/MWh, but could have been as high as Β£121/MWh…has over 29 GW of operational wind capacity’

We’re just not a free country.

Any American watching this play out between regime forces and journalists overseas would recognize it for what it is.

Good point. Here the approach was top-down and we fitted an S curve. This does capture the network effects at the beginning where they act as a brake, but is in contradiction at the end (where the ICE phase out slows down rather than speeds up).

In our case we are not using consumer electronics as a reference class and I agree that would be an inaccurate analogy.

The point here is that what matters for emissions is how many miles are being driven in clean vehicles. A closely related proxy for this is how many of of the total vehicles on the road are clean; i.e. the share of EVs in the "fleet". The problem we face is that the fleet turns over very slowly.
