Perhaps a lot. I live in Boulder and a number of wealthy moms in my social group are all into zero waste, or minimizing waste to the point where they will pay $10-15/gallon for milk. It also helps to justify the price that the milk is sourced locally, because these people are usually cognizant of the carbon footprint from shipping as well.

Assuming those wealthy Boulder moms live in detached single family homes with individual cars, I wonder how much additional carbon footprint of that lifestyle is compared to living in an apartment.

I suspect it is orders of magnitude more than local milk in zero waste packaging compared to what you get at Costco.

A lot of Boulder homes are relatively small because they were built in the 40s-60s for a population with much more modest means. So it isn't rare to see millionaires living in a 1300 SQ ft ranch style home, and driving EVs or riding bakfiets style bikes around toting kids.

So, probably still more carbon intensive than city dwellers, but not necessarily as bad as other forms of suburban lifestyles, and that doesn't mean their efforts are for naught.
