The amount of drivers who absolutely lose their shit when asked to keep pedestrians safe is infuriating. You're driving fucking tanks that can obliterate the human body. You should be held to far higher safety standards than currently exist, and you're still whining. Grow the fuck up.

What @notalawyer.bsky.social said.

🧵 I have a few thoughts as a single mom of two YA kids who are the sun and moon in my sky and who now live across state lines. These go out to other parents whose kids have left (for college or a job somewhere else) and are in the throes of grief and bewilderment. My main message is TAKE NOTES. 1/

Yes! Yes yes yes. Half the conversations I had at Climate Week were about how shitty & stupid climate funders are, and the central complaint is just this: they don't fund movement infrastructure. It's all one-off, campaign-based. Leaves nothing behind, builds nothing.

My first job was a transit and rail engineer/planner. Civil engineering is cool and it's a cool college major even if you don't end up working in engineering.

“The average [Californian] born in 2024 will likely face up to $500,000 in additional lifetime costs from climate crisis, and those who experience more severe effects will see up to $1m in costs." www.theguardian.com/us-news/2025...

It’s great that the EV transition is going so fast in Denmark! But. The significant tax breaks incentivise bigger cars and more driving. And contrary to previously, the taxes doesn’t cover the externalities. That’s why we need roadpricing. #dktrp #dkgreen #dkpol politiken.dk/klima/art105...

More bikes than cars. That means more people moving in less space with less public cost, less pollution, more retail spending, longer and healthier lives, greater happiness etc. In more and more centre cities the Simpsons is proving prophetic.

Why do headlines say "norms shattered" when what is meant is "laws broken" or "Constitution violated"?

A client was recently sharing all the plans/strategies created for their city over decades, and how they always had “bad timing” that some shock, usually economic, would commonly follow the plan’s completion. But good strategies aren’t dependent on the absence of bad shocks. They plan for them. 1/

List 3 things you can talk about for 3 hours without prep: 1. Climate action 2. Transport planning, particularly parking 3. Danish politics

Today on Volts: "dry printing" of battery electrodes avoids toxic solvents & big industrial ovens, but engineers have struggled to make the process cheap & fast enough to compete. Now a company called Sakuu says it has cracked the code & is selling 3D battery printers. I talk with the CTO about it.

Let's just be clear on this. 600 billion dollars is enough money to decarbonize the entire US power grid. But somehow our species is spending that money on trying to build a machine which pretty nobody wants, except like the 5 richest guys in the world. www.nrel.gov/analysis/100...

Gatwick expansion blows another huge hole in the UK Government's already perforated climate commitments. New article on Gatwick expansion with my @tyndallcentre.bsky.social colleague Dr Lois Pennington @loispennington.bsky.social climateuncensored.com/gatwick-expa...

Why offer a report on future threats when you don't care about the future?

"Aviation expansion is not about fairness, nor the economy, and certainly not the climate. Behind slick and carefully crafted headlines, it is about privilege; protecting the frequent-flyer advantages of the few, paid for by all, while sacrificing the many."

To be clear, “sufficient” is here not to be understood in the modern ‘essential needs met within planetary boundaries’ term, but as “enough”. (Whatever that means.)

In the US, even a “cheap” transit bus costs 2-3x more than in Asia or Europe -- and one agency may pay twice as much as another for nearly identical vehicles. In Bloomberg, I explored a ripe opportunity to improve transportation by applying Abundance-coded, supply-side reforms. 🧵

Traffic lights in Copenhagen are synchronised so a rush-hour cyclist at 20km/h can catch green lights all the way. “It’s so important to have the freedom on a bike to just ride along at a good speed… You can feel the city wants you – and supports you – going on a bike.”

Keir Starmer's aides are reportedly telling him not to go to the COP30 climate conference, because Reform would attack him for it. Yes, they might. And he should wear it as a badge of honour. Standing up for humanity, for science and a habitable planet. Where's the hazard in that?

Interesting-looking new study on the impact on European regions of ETS2 which will increase the price of heating and transport from 2027 doi.org/10.1016/j.en...

Some cheery thoughts from me this week (bear with it, I do think there is cause for hope!). www.technosphere.earth/roaming-deat...

Fully agree that EU rather should extend the ETS to cover the full climate impact of aviation (right now only the CO2 from flights within EU is covered).

Parking policies is again a major theme in the upcoming local elections in Denmark. Particularly in Copenhagen where the incumbent mayoral party wants *sufficient* parking, and the challenger wants *much less*. So, today I try to add some facts to the discussion: www.berlingske.dk/synspunkter/...

Since you all are talking about interventions at the Climate Summit 2025: 1) remarkable how Jinping’s 1st sentence refers to the 10 year anniversary of Paris Accord 2) Remember: China tends to underpromise, always 3) China is not going all electrostate for normative climate leadership purposes

Sorry but parking "cops" are good, unarmed civil servants rightly ensuring access to public spaces remain accessible. I own a car and almost never get parking tickets because I park correctly and in consideration of other people who need curbspace.

Xi Jinping announced China's new climate targets personally, a positive gesture, but the targets brought little clarity on China’s future emission pathway. Targeting a 7-10% emission reduction by 2035 from an undefined "peak level" undersells China's current clean energy boom.

This is a great short piece worth thinking about when it comes to transportation & urbanism. “We cannot optimise both proximity and mobility. Proximity and Mobility cannot be friends. We settle into one of two worlds: (a) high proximity, low mobility or (b) high mobility, low proximity.”

it's going to be like when we got rid of smoking in restaurants and on airplanes and within a matter of maybe a year everybody was like "we allowed WHAT?"

It's weird - but now in Oslo, there's so many EVs that you notice the noise and the smell from individual ICE cars, and you realise how much we've been normalising it for ever. You can smell them half a street away. And inside parking lots are just *quiet*.

America: Renewable energy doesn't work. China: Hold my baijiu.

Fossil fuel drilling, refining, and transportation already occupied huge amounts of land, as expertly documented by the photographer Edward Burtynsky. These land uses are much more destructive than solar panels!

Yes, and downtowns are the easiest places to eliminate parking mandates. Much of the parking is already open to the public. Much of it is already priced. There is parking enforcement. Public transport, bike, taxi/ridehail, walk options are usually more viable for downtown than anywhere else.

Parking mandates hurt downtowns: “If off-street parking is required, as it is in many cities, then it becomes rational for firms to locate in places where land is less expensive, meaning it becomes rational to locate outside the CBD [Central business District].”

Great to sit down together on the margins of UNGA.
