Exactly. Because government sponsored social engineering always works out so
well.

serial contrary views?

Usual problem with these sort of tests, they are only measuring one
type of pollutant. Tends to lead to simplistic "cures" that only
address part of the problem.* It was the same concentration on one
pollutant and ignoring the others that gave us the Diesel Disaster.

That is a symptom, not the problem.* The problem is by wanting a quick
political fix for CO2 emissions they ignored the fact that diesels are
responsible for much greater general pollution even if the
manufacturers hadn't been cheating on the tests.


Taking you at your word, that may be a problem.

But where is the "disaster"?

[By that, I mean other than the financial disaster which has befallen
anyone stuck with a running term of car finance and now having to find
an extra £62.50 a week - or more - simply to be where they were before
Khan stabbed them in the back. Obviously.]


The health problems it is causing.

At the time when the government were pushing for diesel cars, all the
green lobby were bemoaning how much more CO2 petrol cars emitted than
diesel, so all petrol cars must be replaced immediately by diesel ones.
When it was pointed out that petrol ones were cleaner in other ways than
diesel, they effectively just put their fingers in their ears "La, la,
la. I can't hear you. Got to reduce CO2 to save the planet"


CO2 is the important pollutant, all the others are irrelevent. If all traffic
stopped now the particulates and NOx would be gone in a day. The CO2 will still
be around for thousands of years to come.

Slightly related to this, I run a G-Wiz, and have worked out that using


Why? Apart from having no crash protection they're small, slow and have a very
limited range. They're 1980s engineering.

the normal mix of generation in the UK, my CO2 emissions are equivalent
to a petrol car doing 40 MPG.


That seems a bit pessimistic to me, especialy given UK generation has run
without coal now for a week.

It's nice that you know more about my personal circumstances than I do,

CO2 is a greenhouse gas, but far less potent in that respect than water vapour
- but no-one suggests
trying to reduce emissions of water vapour! Neither gas is a pollutant, they


I can't believe people are still rehashing this tired old excuse for not
cutting CO2 emissions.

photosynthesis without which all life would cease. Moreover, horticulturists
deliberately increase
atmospheric CO2 concentrations in greenhouses and polytunnels to boost crop
yields.


*sigh*. You might as well state that because all plants require water why not
plant them underwater. Also there are different type of photosynthesis and
when the temperature goes up the most important one stops working properly.

https://en.wikipedia.org/wiki/C3_carbon_fixation

"The C3 plants, originating during Mesozoic and Paleozoic eras, predate the C4 p
lants and still represent approximately 95% of Earth's plant biomass, including
important food crops such as rice, wheat, soybeans and barley."

"C3 plants cannot grow in very hot areas "
