wouldn't worry about it. these are UK articles from 2018 - nothing new to report. London has long been much more restrictive when it comes to vehicles driving in the city limits.

there will always be exemptions for older cars in the US. might get harder to find fuel in 30 years, but we'll still be cooking with oil. the percentage of total vehicle emissions that comes from 35+ year old private diesel cars operating in the US (versus brand new gassers) is practically zero.
