I don't understand how any pollution would be removed, just because it's now in tunnels doesn't equal it being gone.
Wouldn't it just be blasted back out through the ventilation system? Or were there plans to build some kind of "pollution scrubbing" into those?
- deegles 8y agoI think the tunnels would run electric cars/trains only.
- Symmetry 8y agoAlso, cars use a minimum of CO2/mile when traveling at 40mph. Time spent idling in traffic is time spent burning gas to no purpose and to the extent that these tunnels decrease surface traffic there are add on benefits.
- enraged_camel 8y agoOkay, but what about the (probably massive) upfront environmental costs of digging the tunnels and building their infrastructure?
