Today the official full-year car registration data for 2025 was published.
Looks good. And 2026 will be even better, with the many smaller EVs now hitting the market.
Note: The fleet only increased by 50,000 cars, so the EVs are mainly displacing ICE cars -> BEV fleet is about to pass diesel! 😀

Republicans are literally dismantling US democracy in front of us & the US media is glaringly, obviously inadequate to the task of covering it, so they all just desperately want to return to the equilibrium, where they all shit on Biden, all nod at one another, all celebrate one another's bravery.

Today, electric cars outnumber diesel cars on Danish roads ⚡🚗
Five years ago, Denmark had just 32,000 EVs. Now they’ve overtaken diesel – powered by lower prices, policy certainty, and a fast-growing charging network.

Ah, which country is doing that (or even trying to do that)?
Countries deploying wind, solar, EVs, etc, seem to be doing just fine to me. Modelling does not suggest that climate policy screws your economy either.

🚙 Global road transport emissions could peak as soon as 2025, driven by policies adopted over the past 4 years.

The gap: 58 billion avoided tonnes still needed to meet Paris Agreement 🎯

The US—already a laggard on electric vehicle adoption—fell further behind Europe & China in 2025. Both Europe & China have substantially increased their EV market shares, while the US EV market share fell from 2024 to 2025.

A striking part of the reaction to ICE is the solidarity of those not under attack with those who are and the incomprehension of the right who think it's madness or secretly someone is paying and organizing, because self-organized determined resistance mystifies them.

Important verdict.
Wondering what implications, if any, it might have re Denmark’s responsibilities to curb climate change, particularly affecting the Arctic, and thus Greenland.
