In Response to Pollution Spike, Paris Temporarily Halves Traffic By Decree
As reported by News.com.au, the city of Paris has implemented a harsh (but temporary) measure for drivers, in response to a surge in pollution: banning cars with even-numbered registration plates from the streets. According to the article,
City mayor Anne Hidalgo had asked authorities to prevent one in every two cars from taking to the capital’s streets and make all public transport temporarily free in a bid to drive down pollution. Only vehicles with numberplates ending in an odd number will be allowed to drive, though exceptions exist for vehicles like taxis, electric cars and ambulances. ... Public transportation is to be free until at least Monday in Paris and its surrounding towns in an effort to force pollution down by coaxing drivers to give up their cars for a few days. Similar emergency measures were last implemented almost exactly a year ago — on March 17 — during a particularly bad spike in the pollution levels.
Utter nonsense. I drive a French car which is a 2Litre diesel and it's cleaner than either its 1.6 or 2Litre petrol engined models.

Except it's not a question of green. CO2 emissions here aren't what's causing the problem, it's particulate matter and Nitrous Oxides.
From your own link your diesel produces double the NOx emissions.
Not wanting cancer trumps the minor differences in CO2 emissions between the models, and diesel is definitely no longer considered greener or healthier the way it used to be.
The diesel sold in Europe is much better fuel than the one we dump into trucks and trains. Lower sulfur, for one thing, although we are catching up. Most environmentally friendly motor fuel is diesel (no, it is not the remote-polluting electrics; look at the output of, for example, the Four Corners power complex). Modern biodiesel burns clean and has a very low carbon footprint. Soot traps take care of the particulates.
Additionally, diesel fuel has much more energy available by volume or mass, is less flammable, and hygrophobic (doesn't pull water from the air into the fuel tank) than the lighter hydrocarbons (gasoline, methane, ethanol), or hydrogen (unless fused, of course)
I wish I could have purchased the turbo-diesel version of my Jaguar XJ, rather than having to settle for an XJ-R.
I agree, but there's nothing in the article to suggest that it'll be half the vehicles today and the other half tomorrow. Instead it says "Only vehicles with numberplates ending in an odd number will be allowed to drive... for a few days" You'd think it'd be odd numbered plates on odd numbered days and even plates on even days, but that's not what it says.
"It" being an Australian news source that is being a bit vague. What actually happens in Paris is that it goes by whether the day of the month is odd or even. Monday is 23rd, so only odd digit cars are allowed on the road. If it extends to the 24th, then only even numbered cars will be allowed.
And the ban certainly does apply within the city. Pleading ignorance will still get you a fine.
