Reducing traffic with β€œcarrots”: A review of the evidence Reducing traffic volumes is one way to reduce carbon emissions from the transport sector. Since increasing driving costs is often met with public resi…

Yet another evidence review argues very strongly that simply providing alternatives to driving doesn't reduce driving

This isn't surprising, if only thanks to habit. If I unthinkingly jump in my car for every trip (as many do), new buses won't change that

@bmj.com, a renowned health journal, slams car bloat:

"Cars are becoming steadily larger, [and] with this comes potential harms to health...Action is needed locally, nationally, and internationally to curb sales of new SUVs and to reduce their presence in urban areas."

EV drivers could face new tax in Budget The BBC understands there have been

Clearly a lot of details to work through in how it’s implemented but this new pay per mile charge for EVs is a necessary& fair policy. Hope HMT are engaging with devolved nations & local gov on its design as this is a real opportunity to think creatively & more holistically about motoring taxation

Low-income areas in England and Wales face worst air pollution, analysis finds Exclusive: Experts say impact on people of colour and those who do not drive is β€˜grave environmental injustice’

Analysis from @friends-earth.bsky.social provides new insight on environmental injustice in the UK:

β€œβ€¦ people of colour, those on low incomes and non-drivers are now disproportionately overrepresented in the 5% of neighbourhoods still exposed to the most extreme air pollution.”

Sounds like a great trip! We’ve just got back from over a week in Rotterdam and used the trams most days. I really enjoyed it but the 4yr old loved it - especially the bits on grass or by the water. Really easy to use with the 1yr olds buggy too.

Really the only downside to having an electric cargo bike is inevitably becoming boringly evangelical about how good they are πŸ˜… If you’re thinking about it, do it. Zero regrets.

Load and behold: should you opt for an electric cargo bike over a second car? Cargo ebikes are ideal for the millions of short-distance car trips Australians take every day. Here’s how to make one work for you

Love this on e-cargo bikes & family life:

β€œForgoing a second car may have been the reason we bought it, but it was simply more fun to see my son grinning on the bike.”

β€œYou see the joy that the kids get out of it, the time you get to spend with them … [and] it encourages you to use it more.”

Chief Raoni: β€˜The Amazon is our biggest chance to keep living on this Earth’ The Indigenous leader on the threats to his KayapΓ³ tribe, why ancestral knowledge matters β€” and the meaning behind his β€˜visions’

It barely gets any attention, but the Amazon rainforest is on the brink.

I was fortunate to meet Chief Raoni, who has helped to protect an area of Brazilian forest the size of Portugal, and who - at the age of approximately 90 - just keeps on fighting. Please read:

Exactly the same on our narrow residential streets here in Bristol. Positive that councils are starting to act & the public are (mostly) on board with it. Totally agree there should be nationwide action to address the externalities caused by vehicle design/size (eg through reforming VED)

Bravo Cardiff.

β€œIt’s only fair that those driving the biggest, heaviest and most polluting vehicles pay more for the extra space and danger they bring” - Spot on from @olord.bsky.social

Important: two-thirds (66%) of respondents to the related consultation agreed larger vehicles should pay more.

An Austrian adaptation of the Barcelona Superblock, Vienna is putting the finishing touches on its first SupergrÀtzl ("Super neighbourhood") in the tenth district, where through traffic is filtered out to regenerate an intersection into a liveable, climate-adapted, pedestrian-friendly public space.🧡

"People in the UK are already experiencing the impacts of a changing climate, and we owe it to them to prepare, and also to help them prepare. Adaptation in the UK is not keeping up with the increase in climate risk. The impacts on the UK are getting worse and (the government) needs more ambition”

Switching 50km/h speed limits to 30km/h would protect cyclists while barely affecting commutes, research finds One expert says a cyclist hit by a car travelling 50km/h has about a one-in-ten chance of surviving, while at 30km/h it was a nine-in-ten chance

New study from Melbourne finds reducing residential speed limits from 50km/h to 30 km/h on local roads would protect cyclists from danger, make riding less stressful and get more people cycling while not causing traffic delays for cars.
