There are complex trade offs there: housing uses more power than a parking lot but it also provides far more significant social goods, housing can be built with very different levels of energy usage and external heat emissions, and while people need housing they don’t need cars the same way so you can offset a substantial fraction of the pollution from housing by reducing the number of cars used by residents.
The main lesson I draw is that everything would improve by taxing externalities: the land is vacant because the property owners doesn’t have enough incentive to do something useful with it and we have a lot of inefficiency in our housing and transportation which a carbon tax would go a long way towards reducing.
