Maybe the solution is dense, high rise concrete buildings surrounded by woodland. The size of the woodland being determined by the net emissions from the concrete.

The emissions occur during production. Concrete itself doesn't emit CO2, it's the cement being made from limestone that generates emissions.

I might even prefer that to living in suburbia if you also added room for commercial zoning.

I think the way we designed cities around cars could really stand a serious second look. Cars are really a necessary evil for me. I just bought one after 6 years of not having a car. I wish I didn't need it.

I hear that. We can put bike lanes and a tram track beside the building, shops and amenities at the bottom, and room for food trucks to come and go. It'll be perfect.

More seriously, sorry to hear about the car. It sucks to be that way. I've always been lucky enough to arrange my life around access to public transport (I don't drive) but I've been tempted many, many times.
