> Levels of asthma in London are highest among kids in the vicinity of the docks
Someone else pointed out that there's very little shipping in central London now. It's all cars and buses causing this pollution.
> In fact if you try to do anything about inner city pollution you can pretty much guarantee an angry pushback.

There are still cruise ships that dock, and they have been a big issue for local kids. They use a lot of power while docked. I believe the solution is to hook them up to the grid, but that requires that they and the dock both have the facilities.
There is a dock in the Greenwich area, and another one further down the Thames estuary.
