Which is more sustainable: online shopping or shopping in bricks-and-mortar stores?
Construction of malls must have a colossal carbon footprint, and running online stores should be better, I think. On the other hand, the fact that you don't actually see the goods you buy increases the risk that it won't suit you and you'll ship it back (or it'll just have been manufactured for nothing, with all the associated carbon emissions). Those are just a couple of factors. Was there a comprehensive academic analysis on the matter?
