It may have dropped pollution in Manhattan but I guess more pollution added up to the surrounding borroughs in addition to more traffic.

> but I guess more pollution added up to the surrounding borroughs in addition to more traffic Why? Fewer cars into Manhattan means fewer cars through the boroughs. And even if they all diverted, you’re still looking at less idling and less stop and start braking.

  Not necessarily. I use my brake far more in stop and start traffic on the highway than I do in Manhattan. In the city stop and start is primarily determined by traffic lights, which are predictable, rather than the traffic itself.

    > I use my brake far more in stop and start traffic on the highway Is that because of gridlock or because of the higher energies? > In the city stop and start is primarily determined by traffic lights Source? In my experience it's unexpected incursions, whether that be cars changing lanes, pedestrians stepping off the sidewalk or food-delivery bikers yeeting themselves into an intersection.

Good question, this happened in London for sure, congestion charging increased the net pollution from vehicles but reduced the metrics inside the city, probably not much either way.

This was a common anti-congestion pricing talking point, but it ends up not being the case. People either don't drive into the city, or they take transit.

The article speaks to this as well, "Pricing led to a drop in pollution across the greater metropolitan area, according to the study, published in the journal npj Clean Air." So while this was/is a common sentiment about congestion pricing, looks like it luckily didn't pan out.

The study found the opposite: people are picking healthier choices throughout the region. This makes sense: if you switch to taking the train, in addition to not driving in the congestion zone you also aren’t driving the distance between the closest train station and Manhattan, which for many people will be more engine operating time than they spend in the zone itself.
