Dramatic fall in London’s levels of deadly pollutants after Ulez expansion

  People in London have been breathing significantly cleaner air since the expansion of the ultra low emission zone (Ulez), a study has found.

  Levels of deadly pollutants that are linked to a wide range of health problems – from cancer to impaired lung development, heart attacks to premature births – have dropped, with some of the biggest improvements coming in the capital’s most deprived areas.

Who'd have thought vehicle emissions were so bad and that life could be better by reducing usage in dense urban areas?

I think rules as a concept are kinda under attack. This ranks really below my radar on shit to care about in the current situation.

Is there a steelmanned argument on why this matters for anyone atm?

Zero emissions sounds like a silly goal anyway, 80/20 and all that.
