Abstract: How a city grows and changes, along with where people choose to live likely affects travel behavior, and thus the amount of transportation CO2 emissions that they produce. People generally go through different stages in their life, and different travel needs are associated with each. The impact of the built environment may vary depending on the lifecycle stage, and the years spent at each stage will differ. A family with children may last for twenty to thirty years, while the time spent without dependents might be short in comparison. Over a family’s lifecycle, how big of a difference might the built environment, through household location choice, have on the amount of transportation CO2 emissions produced? From a climate change perspective, how significant is residential location on the CO2 produced by transportation use? This paper uses data from the Osaka metropolitan area to compare the direct transportation CO2 emissions produced over a family’s lifecycle across five different built environments to determine whether any are sustainable and which lifecycle stage has the greatest overall emissions. This understanding would enable the design of a targeted policy based on household lifecycle to reduce overall transportation CO2 of individuals throughout one’s lifecycle. The yearly average per-capita family lifetime transportation CO2 emissions were 0.25, 0.35, 0.58, 0.78, and 0.79 metric tonnes for the commercial, mixed-commercial, mixed-residential, autonomous, and rural areas respectively. The results show that only the commercial and mixed-commercial areas were considered to be sustainable from a climate change and transportation perspective.
