>...London’s Taxi Private Hire regulations, which from 1 January 2018, banned new diesel-powered taxis and requires zero-emissions capability.

I dare say the old ones will trundle around a while yet. Nothing's prefect.

For up to thirteen years apparently: https://www.whatdotheyknow.com/request/spread_of_ages_of_lon...

According to that, max age of a black cab is 15 years. On the plus side, given the age distribution shown, then about 10% of the black cabs will already be 0 emission.

There is already an age limit in place for existing diesel cabs, it is being reduced from 15 to 12 years for earlier models - additionally, TFL will pay up to £10k to delicense caps not built to the latest standards.

Do you have a source for that? Dropping that age limit from 15 to 12 years would obsolete about 20% of the fleet overnight, since the age spread of the cabs is fairly linear.

So it isn't overnight, it's gradual, it will accelerate fleet replacement significantly, but not 20% of the fleet overnight.

IIRC they have a mandated max life of 13 years.
