Pardon my massive ”old man yells at cloud” energy, but when did it become normal to just completely ignore emails? I feel invisible.

Remember, with or without COP events, smart nations know that INVESTING in cities taking #ClimateAction is one of the smartest investments nations can make. The cost of NOT doing it is FAR too high, in ways we can count & ways we can’t. @mayors4climate.bsky.social #ActionStartsHere #PaidPartnership

Here is the message to #COP30 from mayors and local leaders from all over the world - and what we need to move from negotiation to action.

It's World Town Planning Day and by happy coincidence I'm in one of the world's most planned cities I first saw pictures of Brasília when I was about 11 - it's almost certainly the reason I became a town planner Whatever you think of the outcome you can't help but admire the ambition and hope

Climate action entails transition. + All transition is local. = Local politics is important.

Such a privilege to speak with and learn from this group of incredible leaders. I wish everyone who feels disillusioned with politics could be here to see that the overwhelming majority of political leaders choose to take on that responsibility out of a will to change things for the better.

Over 30 cities announced their yearly offers of action. “Acting together with urgency and determination, we're confident we can truly turn the tide and secure a safer, more resilient world for the generations to come. The yearly offer of action is the way it’s going to happen.” - Yvonne Aki-Sawyerr

👏 C40 Cities Co-Chairs, Mayor of @london.gov.uk Sadiq Khan & Mayor of Freetown Yvonne Aki-Sawyerr, celebrated that 73% of C40 cities, for which data is available, have peaked their emissions, with 23 cities delivering a 17% reduction compared to their peak. #WMS25

National governments continue to dither and delay on the climate crisis. At the @c40cities.bsky.social World Mayors Summit, local leaders are pushing ahead with bold action. When it comes to the future of our planet, now is not a moment to slow down, but to double down.

Who needs some good news? 🙋‍♂️ Today my amazing team at C40 are launching new research showing that emissions have peaked in 60 of our member cities - 75% of those for which we have sufficient data - meaning absolute emissions have reached their maximum and are now on a steady downward trend 📉

C40 Cities Co-Chairs, Mayor of Freetown Yvonne Aki-Sawyerr, and @mayoroflondon.bsky.social, @sadiqkhanlondon.bsky.social, ready to open the 2025 World Mayors Summit in Rio de Janeiro. #WMS25

The most insanely frustrating thing about the #ClimateCrisis is how the breakthrough we so clearly need isn’t technological. It’s just a collective willingness, a determination even, to change in ways that would clearly be SO MUCH BETTER than the clear and obvious consequences of NOT changing.

🎉GOOD NEWS: C40 cities reach a milestone of 21mn good green jobs 🌱👷 More than 10% of all employment in 81 global megacities is now green - and C40 mayors are on track to deliver their pledge of creating 50mn good green jobs by 2030. @london.gov.uk @sadiqkhanlondon.bsky.social

Not only was my home town a destination on Swedish tv’s Friday night rail-travel-based quiz show ”På Spåret” - my great-great-great Aunt Emmeline (Pankhurst, a leader of the British Suffragettes) was the answer to a quiz question

In the US, zero-emissions trucks & buses represented 0.6% of the market in 2024. theicct.org/publication/... Meanwhile, in China, battery-electric truck sales are booming, representing 22% of the market in the 1st half of 2025, up from 9% in 2024. ieefa.org/resources/su...

In around 2030 Stockholm will have a new metro station called Sofia. In the meantime you can ride this fine metro system in the city of Sofia which has one or two fascinating features…

It’s Kanelbullens Dag, that’s to say, Cinnamon Bun Day in Sweden. And while I mean no disrespect to Norway and Iceland, who also mark this day, it’s Swedish Cinnamon Buns that are #RecipeOfTheDay! www.nigella.com/recipes/swed...

Some mornings the tram is really the only way to travel - Tvärbanan in Stockholm is another of the projects I am proud to have contributed to

The 🇧🇪 Belgian postal service claims to be the first emission-free postal service in a European capital. All deliveries in the 19 municipalities of the Brussels capital region are now made on foot, by bike (some with e-trailer) or in an electric van.

Happy Birthday to Stockholm’s metro, Tunnelbanan - keeping the city moving for the last 75 years 🎈🥳. Ja må den leva uti hundrade år!

I may have found my defining quote. Pair this with my pinned post and you will see what I mean!

To state the obvious: if acceptance and even celebration of war crimes was the secret sauce for military success, the Russian army would be in Paris by now.

Electric Trucks Are Rapidly Approaching A Tipping Point — Just Not In The US cleantechnica.com/2025/09/23/e...

Over the past decade, local governments have shown that they can deliver some of the most effective and rapid climate solutions. Cities are not waiting for international agreements, they are taking action. @c40cities.bsky.social @mayors4climate.bsky.social www.linkedin.com/pulse/turnin...

I think this is the year that we should finally retire the word "gentrification." You can't measure it and you can't define it, so how do we know when it started and if it stopped?

It's absolutely astonishing: In just about 13 years, Norway has skyrocketed from virtually no sales of zero-emission battery electric vehicles to nearly 100% of all new passenger car purchases.

To realize the Right to Housing we need an effective right to build housing. Unfortunately that's not universally understood. E.g. the City of Vancouver has called on the province to declare housing as a human right, but at the same time it continues to severely restrict the building of housing.

Electrification is vastly more efficient than combustion technologies: 🚘 An electric car uses about 75% less final energy than an ICE car. 🔥 A heat pump delivers about 4x more heat for the same energy input. Note: Of course the exact efficiency and saving will differ between models and context.

Positive tipping points for climate, like the UK phasing out coal, show how big steps toward a low-carbon future can suddenly become unstoppable. Can we identify where the next tipping points could happen, and figure out how to help trigger them? These researchers say YES. Read more:

The share of battery-electric cars in Europe is only going in one direction: Upwards. But there are remarkable differences amongst countries with some countries exceeding 50% and others below 5%. Much of this can be explained by policy or absence of it. Source @electricnick.bsky.social

I love when the city turns into a giant illustration of traffic priorities ❤️

A colloquial Swedish word for giving a confident answer to something you know nothing about is killgissa, or “guy-guessing.” Conversely, the lesser-known word tjejveta (meaning “girl-knowing”) can describe elucidating (shelucidating?) on a topic you have expertise in.

A few days ago, Berlin opened a new stretch of urban motorway, with the stated aim to reduce congestion. Today, the stretch was temporarily closed because of too much congestion.

There’s a word in modern Swedish slang, smygflyga, which describes not admitting to taking a flight because of shame about carbon footprints. It literally means “sneak flying.”   And the word tågskryta describes when you proudly tell everyone that you took the train instead (literally “train brag”).

The adoption of EVs is surging in emerging markets, as affordable Chinese models help drive down prices With rising Chinese EV imports, battery electric cars have reached price parity in Thailand & seen major price drops in Brazil & other markets ➡️ iea.li/4khAEd6

There’s a Tamil phrase, adopted from a comedy movie, that can be said to someone who minimises your pain but makes a big deal out of their own. The phrase is unaku vandha ratham enaku vandha thakali chutneya and it means “if you bleed, it’s blood; if I do, it’s tomato sauce.”

The evidence is clear: 20mph zones save lives and don’t slow traffic ⬇️ www.theguardian.com/commentisfre...

Side Track är mer än en bar – det är en trygg plats, en mötespunkt och ett stycke levande queer historia. Det är Sveriges äldsta gaybar. I 33 år har den överlevt båda de epidemier som plågat vårt community, bara för att slutligen falla offer för dem som inte värdesätter Stockholms queera kulturliv.

We need a realistic, adult conversation about taxes, but neither politicians nor journalists are prepared to have it inews.co.uk/opinion/time...

“Don’t litter London’s parks”. One of the GLC’s anti-nuclear posters featuring the iconic imagery of Peter Kennard that was commissioned by the Council.

It’s been Pride in Stockholm this week which means a visit to our prettiest metro station, Stadion. (Yes I do look tired, like I say, it’s been Pride all week!)

Motherfucking wind farms…

What has been the impact of Norway’s shift to electric vehicles? New study finds: “… BEV ownership leads to an overall increase in car trip demand in the order of 10–20%. This reflects shifts from ICEV to BEV use, but also sizeable shifts away from public transport use, cycling and walking.”

Why is Tokyo so fashionable? Some theories. 🧵

Obsessed with my Tour de France-themed cheese spread. (Though obviously not so much that I didn’t manage to eat three of them before noticing 🫢)

With the right funding, cities can better protect people from devastating climate impacts like heat, flooding, and storms. But local governments often miss out on the money they need, even in wealthier cities. Read all about it in our latest journal issue: utppublishing.com/toc/jccpe/4/1

Stockholm is just the latest city where people move to a "cool" neighbourhood and immediately try to dismantle everything that made it "cool" If they succeed in closing our oldest gay bar, I will have to agree with Andersson that we are "a Pompeii of dorkiness" www.aftonbladet.se/kultur/a/OoV...
