An interesting article about energy, netzero and climate change.
Warning! The @DailyMail is carrying an article by me that contains numerous errors, introduced by editors while I was without access to a phone signal or internet, hiking in the Rockies. Below is the correct text that I submitted to them: The climate boondoggle is one of the…
Dundee City Council: "Although it [the LEZ]only started being enforced in May 2024, the area is already meeting air quality targets" The air quality targets inside the LEZ were met in 2022/2023 - long BEFORE the LEZ was enforced.

Running costs for Low Emission Zones An FOI release from the Scottish Government gov.scot/publications/f…
Unbelievable negligence by @Edinburgh_CC! A man was found dead in a locked council toilet SIX DAYS after being reported missing. How does this happen in 2025?! His family deserves answers NOW.
The sheer brass neck of “Honest” John - complaining that Labour have broken election promises. If Swinney makes an election promise before next year’s election then why has it taken 18 years of power to fail to deliver it? 🤔
Here's an interesting question. The Queensferry Road is now 30 mph, but there are road markings that state it's 40 mph. So can you do 40 if the road markings say the speed limit is 40 mph?
Just driven along Minto Street (Edinburgh) - what a mess. It's hard to make out the lanes, because the markings have faded. Old bus lanes with different coloured surface appear to be half bike lanes and half road - then they disappear. CEC - making a mess of the city.
Previous planners had the foresight to create dual carriageways in the 60s and 70s, to deal with the future increase in traffic. Today's planners are reducing the available road space, creating more congestion. Traffic flowed better after the bus lanes were removed.
A89 / A8 🚧 Ground surveys between West Lothian and Gogar. Most work will be nightshift with lane closures and temporary bus stops as required. Starts Mon night 14 July between Newbridge and Broxburn viaduct and runs until late Sept. edinburgh.gov.uk/broxburntogogar #edintravel
DUNDEE Whilst it's good to hear it from someone else, it's not a good idea to compare daily measurements with a figure that is the mean of all the 24-hour figures obtained over a period of 1-year.
Dundee’s low emission zone (LEZ) has been enforced for a year – but is it really making a difference? I have looked at nitrogen dioxide levels both within and outside of the LEZ boundaries to find out. 1/2 #datajournalism #ddj #dataviz
Dundee "council’s website on the LEZ states that there are still locations where that annual level is not being met" dundeecity.gov.uk/service-area/c… A quick check of the monitoring data and no sites exceeded the objective in 2023 (but 2 outside the LEZ were close to the objective) .
I also spoke to professor Jill Belch, clinical professor at the University of Dundee’s School of Medicine, about the impact of air pollution on our health which she describes as an "invisible killer". 2/2 thecourier.co.uk/fp/news/525343… Read more: thecourier.co.uk/fp/business-en…
Measurements of nitrogen dioxide in GLASGOW. There was a huge drop between 2019 and 2020. This was Covid, not the LEZ. NO2 has been falling year-on-year at all sites, except Anderston (a primary school), where it has increased since 2020 And Roadside Hope Street (buses/taxis).

This may result in a significant reduction in air pollution in the vicinity of the docks in Aberdeen. It has to be better running massive diesel engines when the ships are berthed.
Green shore power at Aberdeen's port is operational, reducing emissions and air pollution from docked vessels. This initiative stems from Tyndall Centre's research on viability + policy. Learn more about implications for ports and policymakers ⬇️ buff.ly/YmmQOhH
Passive Diffusion Tube measurements for 2024 have not been published. Some of these figures are already 18 months out-of-date. These figures should be available because the local authority air quality reports should have been published at the end of June.

A new mural in France depicting Lady Liberty covering her face in shame was unveiled the day before America's Independence Day.
This article confirms that the Scottish Government's LEZ charges are the highest in the UK. Something to think about as we get closer to the next election.
Clean air zones are now enforced in a wide range of city centres across England and Scotland to cut pollution 💨 Here are the cities affected and how much they charge non-compliant vehicles buff.ly/rKJ3mhO
Even AI (Copilot) knows if you move traffic closer to pedestrians, the concentrations of nitrogen dioxide will increase. If CEC had done an assessment of the changes to the road layout in Roseburn Terrace, they would have known this before they made the changes.

I warned CEC if the parked vehicles on the southside of #roseburnterrace were removed and traffic moved closer to the pavement, nitrogen dioxide (NO2) pollution will increase. Well - measurements show that NO2 on the southside was 4 µg/m3 higher than the northside in 2023.
#Roseburnterrace is a typical street canyon as shown below. Traffic pollution is 1/3 higher on the leeward (south) side - monitoring has confirmed this. Changes to the road layout have moved traffic closer to the leeward side and this will increase the already high levels.
