Asking the real question here.

In most European cities, if you could free up 30% of space you should probably use most of it for housing.

This would also avoid people commuting from far away, thus saving a ton of energy and CO2 emissions. The CO2 captured by a 20-year tree through its growth is probably emitted in a few months max by a single suburban car commuter.
