I think our diesel emission laws for cars are too stringent (like 1/3 of the NOx allowed in Europe). We've tended to go towards hybrid vehicles as a result. Thing is we still have this massive heavy commercial truck fleet and they all use diesel.

This may be a more realistic and sober analysis.

Seven days to break the annual limit........
Quote:
European Union and British law states that no area should exceed hourly limits for nitrogen dioxide more than 18 times in one year. But a monitoring station in south London recorded 19 breaches of the cap in a single day.

It’s estimated that nearly 10,000 Londoners die prematurely every year as a result of air pollution.

Those 10,000 premature deaths make Chicago's 700 murders look respectable.

How many premature deaths in Chicago as a result of air pollution?

"The group tracked ground-level emissions from sources such as industrial smokestacks, vehicle tailpipes, marine and rail operations, and commercial and residential heating throughout the United States, and found that such air pollution causes about 200,000 early deaths each year. Emissions from road transportation are the most significant contributor, causing 53,000 premature deaths, followed closely by power generation, with 52,000."

The WaPo piece says London air pollution is much worse than US, and your MIT piece confirms, per capita deaths from air pollution in London are almost double the US rate.

London = 10,000/8,500,000 = 0.117%

US = 200,000/320,000,000 = 0.0625%

But you are comparing the most densely populated area of the UK with the whole of the US. A more valid comparison would be London with New York or London with Chicago.

I could compare air pollution in Wester Ross with that of Washington DC but there would be no validity to such a comparison. The same would be true when comparing the whole of the UK to the whole of the US given that the UK is generally more densely populated.

Air pollution is a health problem in both countries and the more so in densely populated and industrial areas. However, I don't think that comparing deaths from that to murders is especially helpful.

Oh no you don't..........You were the one who made the comparison between London and the US, by citing the MIT piece...........not me.

Then when it comes back to bite you.......you try to shift responsibility onto me.

Believe it or not, whether in the UK or US, typically, few people die of air pollution in sparsely populated areas.

60% of the US population lives in the much smaller portion east of the Mississippi. When you reduce population and deaths to 60% you get the same 0.06% rate.

London Pm 2.5 and Pm 10 are both considerably higher than in NYC (WHO and other records). Anyone who has lived in both cities (like me) can taste it in the air without being told that anyway.

I quoted the MIT piece to demonstrate that the US has the same issue with air pollution. That piece specifically stated that pollution was worst in industrial areas such as the Chicago to Detroit area. So my comparison stands and did not come "back to bite me".

But I am glad we agree that the rates of deaths from air pollution are broadly the same which makes your remark about murders in Chicago rather redundant, at least from a UK perspective.

I lived in both cities, albeit not too long. London overall feels far more cleaner (including air), and civilized, than the stinky dump called NYC, just no comparison.
You cannot rely on any US statistics they provide, Americans on average are very poorly educated, I doubt they can correctly measure anything, including Pm values.
