Pricing between two similar products doesn't necessarily reflect difference in impact on the environment. It can also indicate scarcity in resources, an advantage in being the first (which may include setting your own price), protection by patent, or monopoly. Also, scale is another variable. While a rural area may have less-expensive housing and transportation costs than a major city, the city may have more efficient delivery methods and transportation (which could include the upkeep of having lit and paved roads to encourage walking), when accounted for on a per-person basis. However, with some refinement, I think your theory could be potent.
