Expanded ULEZ

[Mottie]

Are there sensors in childrens bedrooms next to busy London roads?

I’ve got no problem with the central London congestion charge or the initial ULEZ area even though it prevented me from taking my own car to my workshop and lost me a fair few customers. I do have a problem with the Khants expansion to all London boroughs. It is just not needed in those areas.

do you have evidence that they aren't?

Are air quality sensors accurate?

While air sensors are useful for providing general information about air quality, air sensors have a number of limitations that could include occasionally reporting questionable data points and a bias that may result in data that systematically over- or under-estimates the actual pollutant concentration


London is one of the most polluted places in the UK, according to the London Air Quality Network. Pollution builds up when it becomes trapped between buildings,


Bad luck if you are anywhere near tall buildings in London, with no sensor to pick it up, eh.

Of course your source [missing as usual] comes from somebody paid to fluff up the argument that London is one of the most polluted places in the UK (which actually means nothing much at all).

"....monitors placed as little as 5m apart can return hugely varying results, as pollutants vary massively over time and space...."

Lol.

I bet you own a damp meter, lol.

Cleaner than Paris, Berlin, New York


From your source - I see you didn't post this bit..

Within Europe London is the largest city, but we have less pollution than some EU cities because we are on the western edge of the continent and often receive fresh air from the Atlantic.

So London, not too bad, ULEZ expansion - just a tax on poor people. Not everyone can afford to go out and buy a Tesla on whim.

Irrelevant.

Sensors, lol.

Might as well stick yer finger in the air, boyo.

London is a polluted shíthole and someone needs to stand tall and clean it up. Good ole Sadiq.

Sensors, lol.

So if you don’t believe in 'sensors', where are you getting figures for pollution in 'London'?

How far out from the centre of London do you believe the polluted shîtehole extends?

So if you don’t believe in 'sensors',

Where did I say I don't believe them?

I merely suggested that your reliance on their random readings is unreliable and that you shouldn't prematurely go skipping to the teacher, just because on gives a low reading at 4 a.m. one morning.

Not as far as Staffs, thankfully.

Good ole Sadiq.

yep such a great place to live - 3 houses for the price of a Tesla.

The 'lol' bit of your post.
