And still no answer from @ScottishEPA .
I was looking forward to reviewing the 2025 nitrogen dioxide passive diffusion tube data - but they still haven't been published. It's almost 2027. @ScottishEPA what is the delay?

Edinburgh Council's traffic convenor claimed a 75% reduction in nitrogen dioxide thanks to the LEZ. This is based on modelling. Monitoring shows Covid resulted in the largest reduction. There was little change when the LEZ was enforced. Euro 6 engines saved the day - not the LEZ.

What has happened to the price of coffee? It has doubled in price and it's going to be a luxury item.

Local authorities use small plastic tubes to measure the concentrations of nitrogen dioxide, and these measurements are published on the Scottish Air Quality website. However, it's November 2026 and the measurements for 2025 still haven't been published. @ScottishEPA Why?

Responding to a 2023 post: Scottish Government's policy of building new homes in locations where there is no public transport, no jobs and few amenities has INCREASED car depedency.
Fiona Hyslop admits the government needs to ditch its car reduction targets as they are "unachievable" and "unnecessary". 🚗 This comes after Audit Scotland said the targets were unlikely to be met due to minimal progress in this area. @TheScotsman 👇 scotsman.com/news/politics/s…

The Council told us that we needed the LEZ to reduce pollution below the legal limits. But pollution was already below the limit, 4 yrears before it was enforced, so this claim wasn't correct. The money should be returned to the people it was taken from.
LEZ raising money for improving services and making our air cleaner. Win. ✅

Passive diffusion tube pollution monitoring data for 2025 have not been published. Some of these measurements are nearly two years old, @ScottishEPA what is the delay? This is public information, why is it not available?

There is 1 automatic air monitoring station inside Edinburgh's LEZ. The Nicolson Street monitor saw a disappointing 3µg/m3 reduction in nitrogen dioxide (2022-26), including a 1µg/m3 drop AFTER the LEZ was enforced. The Drumsheugh site measured a tiny fall of 1µg/m3 (2024-26).

Edinburgh Council appears to have a problem with signs, but a least these ones are facing the right way.
Replying to @edinhelp
Thanks for your reply, the signs don’t match the info on the link. This was taken yesterday.

I notice that Edinburgh Council's case for the 777 Bus Lane Trial in Duddingston doesn't mention climate change or climate emergency. I wonder why? Has it finally realised that it's previous claims were nonsense?

If you look at the measurements of particulate matter (PM10) in Edinburgh, you will see the concentrations are below the legally enforceable limit of 40µg/m3 & the Scottish Government's aspirational target of 18µg/m3. So why has Edinburgh Council added a new particulate monitor?

I haven't been on the Scottish Air Quality website for a while, and I'm surprised to see that Edinburgh has installed another (expensive) particulate monitor in the Leith area. Why? It has run for two months and the levels are VERY low.

Edinburgh Council is proposing to create Sustainable Urban Drainage Schemes in the Craigleith area. See examples in Glasgow. Edinburgh Council has a habit of creating things like this, then it fails to maintain them. Picardy Square is a good example. worldlandscapearchitect.com/…

Had to go to the Ocean Terminal today, and it's seen better days. I remember when it was a thriving retail centre with many of the key shops and restaurants. I hope it recovers, now it's surrounded by 100s of new homes.

I've just been outside (11.15PM), and the wind is howling - but it's warm. Unusual for Scotland, at the end of October.

Edin Council hopes 7 7 7 bus lanes will appear across the city. Well, we can expect to see increased congestion across the city. These are the people who told you that we needed an LEZ to meet legal limits, when the legal limits were met 4 years before the LEZ was enforced.

LTN resulted in no significant traffic reduction, but increased congestion on boundary roads. Just like the failed Manse Road experiment in Edinburgh.
Lambeth Council's own report has found the West Dulwich LTN resulted in “no significant traffic reduction” but increased congestion on boundary roads. The courts found that the Council had acted illegally when installing it & ordered its removal. telegraph.co.uk/gift/fe78242…

My Daughter booked a train ticket to travel from Cambridge to Stanstead. But there were no trains, so they laid on buses. But not enough buses. So she had to take a taxi. She got to the airport to find there is a power failure & a massive queue for security. Is the UK broken?
