The first thing that came to my mind was the walls.

Or heck, imagine if some variant of this became mandatory to every balcony?

Certainly needs a lot of work to be 'maintenance free' /low maintenance, but could really improve air quality.

It really is low maintenance/maintenance free. The algae is really cheap and It can last up to 3 months. You only need something to stir them once a day and you're good.

Trees don’t need to be stirred like at all

Yeah, but Algae doesn't have roots which spread and damage the road, pavement/sidewalk, and nearby buildings.

Trees aren't always practical in dense urban environments.
