Big words, big figures on a subjective subject.
Since the start of the industrial revolution CO2 emissions have increased by roughly. 50%. Pre industrial revolution 280 ppm (max) today 414ppm. But the worlds population has increased by 400%. Using these figures means that those living prior to the industrial revolution were bigger per capita polluters than we are today. Diesel Motorhomes and all.
Now Derek we have a problem and that problem is over population, possibly global warming will be our saviour getting rid of a few billion, whilst maintaining lower birth rates owing to lower reproductive rates.
The worlds Forrest’s used to absorb 50% of all produced CO2. But today that figure is only around 30% with an area of Forrest the size of Wales disappearing every year. So stop cutting down trees and start planting trees could do more than removing all internal combustion engines from the planet.
It’s smoke and mirrors, it’s lets tax the man on the street, it’s never give a sucker an even break, it’s global warming. (We could do with that up here).

Tell me Derek do you believe that we only discovered what comes out of a diesel tail pipe. We have known for decades about nitrogen oxide, and the particulate matter. Yet ten years ago go it was “ dash for diesel” now it’s £12 a day to drive your 4 year old diesel with a Euro 5 engine 80 times cleaner than the first diesels.
The new 6b models have taken levels from 85ppm on the current euro 6 down to 50ppm. In the 1960s that figure was 490ppm,with much higher particulate. Today diesels produce 40% less CO2 than petrol. Yet you can drive a 12 year old petrol in London, but a 4 year old diesel producing much less CO2 will cost you £12 a day.
Smoke and mirrors Derek, nothing definitive, just one thing is certain, more taxes.
Clarity is lacking, detail obscured, and minds are being bent towards concern for the planet.
Today it’s go electric, yesterday dash for diesel.
Tomorrow who knows, but if it’s electric you can bet one thing it will somehow get much more expensive, no matter how beneficial it is to the planet.
