> Your carbon footprint commuting on high-occupancy diesel trains while living in a 50 year old highrise is usually going to be significantly lower than commuting in a Tesla and living in green detached house. I think it could be a tossup, depending on how green the house really is. But making a truly low carbon footprint detached suburban house is still prohibitively expensive in some climates, due to space and water heating needs. If you take the same green tech and apply it in a multidwelling context, then it becomes more economically feasible. You see something similar today with Internet services like iPass that provide gigabit Ethernet service only in buildings with more than a certain number of units.
