So between Person A with no telework who commutes 5km each day by car and Person B with telework who mostly works from home but commutes once every two weeks over 100km by car Person B has higher emissions.

Mmm but if they are not allowed to telework, they will stay closer to A. Whereas the more they are allowed to telework, the further away they will move, and the longer the distance of their commute (because most still commute from time to time)

Uh? How does that result in flights?

We have a new open access paper out, another one from our project "Long-Distance Society" (t.co/1bw0geAKxh)

We find that how much a person flies depends not just on their own characteristics, but also on their partner's, including whether the partner has friends abroad

Very interesting new study finding that 10% of people are responsible for 51% of total emissions from passenger transport in Germany. The concentration is even higher for long-distance travel (10%->80%) doi.org/10.1016/j.en...

Interesting-looking new study finding that substitution to electric aircraft would reduce emissions from *intra-European flights* by just *0.1%* in the short-term, though this may increase later. doi.org/10.1016/j.tr...

Interesting-looking study on the introduction of 30km/h speed limits in Edinburgh, finding it "resulted in a reduction in collisions & casualties 3-year post implementation (with) the effect exceeded expectations possibly due to a wider network effect" research.ed.ac.uk/en/publicati...

“German weekly Spiegel having a bit of a meltdown about the possibility of perhaps importing electric vehicles from China at some point in the future. The article wonders whether the "Autonation" will "survive". 🙄

Technological solutions to decarbonise aviation won’t become a massive-scale reality any time soon. Airlines depicting flying as a sustainable are simply fooling consumers. They must stop greenwashing their activities right away. Our EU complaint: beuc.eu/green-flying

NEW: Transport is on track to make up nearly half of Europe’s emissions in 2030.

Since 2007 the sector has been decarbonising more than 3x slower than the rest of the economy.

This is rather enormous. When you include the full lifecycle and construction, you're accounting for hundreds of kilometers of cement, the manufacturing and eventual disposal of trains and rails and everything else including the energy to move them. A huge amount of emissions.

We urgently need to start talking about long haul though

The point of our study is that banning short haul is not one of the "big" changes. Is a rather small one. And we won't make any "big" change unless we start doing something about long-haul and stop considering that taboo.

I think you are mixing the "what we should do" level with the "what is currently happening" level there.

Mmm not sure. That works in reverse too. Many super-short-haul flights are actually the last leg of a multi-flight journey that involves long-haul flights. Meaning that those people are in the airports already.

As a counterpoint, here is our own study that found out that even banning all super-short-haul flights in Europe would bring about very little emission reductions, as most aviation emissions are from long(er) haul t.co/Zhmg03Dt3h

Hard disagree. They estimate one side of the equation (the negative impacts), which is more than enough for a single study. Other studies can estimate the positive impacts. That's how science proceeds, bit by bit

Interesting new study finds that "carbon knowledge" (about how much activities generate emissions) influences behaviour less than "carbon engagement" (willingness to engage with knowlege on emissions) & that neither influences transport emissions doi.org/10.1016/j.ec...
