If [[walkability]] was achieved by building brand-new neighborhoods, how long would it take to "break even" considering the carbon emissions of building the new homes/buildings?
If [[walkability]] is achieved by building brand-new neighborhoods, how long would it take to "break even" considering the carbon emissions of the construction & materials?


Simplified model:
==Simplified model==
* consider the carbon footprint of making a new building, per person living there.
* consider the carbon footprint of making a new building, per person living there.
* assume a full extreme lifestyle change: people go from "USA average" amount of driving, to zero driving.

The real-life figure might be higher because...
The real-life figure might be higher, because...
* can't really expect a full change to ''zero'' driving, just a lot less than before

* the calculation didn't include interior furnishings of the building, as far as I know

The real-life figure might be lower, because...
* the footprint of heating the new place would probably be lower than the old place
* the footprint of heating the new place{{x|i.e. an apartment or condo in a multi-unit residential building}} would probably be lower than the old place{{x|i.e. a single-detached suburban home}}
* less construction in other ways (especially road maintenance)


In any case, the carbon payoff of new construction could be worth it if there's no better option for [[Walkability/Existing housing]].

<!-- TALK: should i try to find a different case study that deals with per capita (or total emissions and total number of residents) instead of guesstimating floor space per person -->
