Politicians are constantly exhorting us to get out of our “polluting” cars and onto “clean” public transport – and criticising us – from the comfort of their chauffeured limousines, of course – for not doing so.
Well you can rest easy: in your car, you are in the least polluting form of motorised conveyance. Using publicly-accessible sources quoted in the references below, a very different picture from the political dogma emerges:
Cars and taxis account for 77.8% of all national road miles travelled, but are responsible for just 12.4% of national emissions of CO2, 13.5% of national NOx, 5.1% national PM2.5 and 4.7% of national PM10.
Further, on an emissions per billion kilometres basis, a typical bus would need to permanently (24/7 x 365) carry a respective minimum of 25 and 20 passengers to achieve parity on NOx and PMs with a typical, singly-occupied private car. If the car is carrying, say one-, two-, or three passengers, the numbers get worse for public transport by a factor of two, three and four; dramatically further worsening if the car is Euro 6 compliant.
|Vehicle Type||BnVkm (2017)3||% of Total Distance travelled (2017)||% of National Man-made CO21,2||% of National Man-made NOx1,2||% of National Man-made PM2.51,2||% of National Man-made PM101,2|
|Cars & Taxis||409.4||77.77||12.40||13.47||5.14||4.72|
So don’t let duplicitous politicians and eco-zealots pull the wool over your eyes. Persecution of car drivers on emissions grounds is entirely unjustified. Accept NONE of their car bans, ULEZs etc which are all empty virtue-signalling to disguise rapacious, entirely revenue-led policies which have no justification in fact – and even less in science.
