This is the least credible reason to not use Amazon.

They treat their warehouse workers cruelly, tolerate counterfeits, allow the review process to be juked to the point of uselessness, and contribute to a brittle monoculture.

But the environment? Any consumer good is transported by internal combustion engine from the factory, to some intermediate places, to the door. Maybe someone uses a bike for the last part, but mostly, they drive to the store in their private automobile. Amazon uses package delivery services, which is much more efficient, and warehouses have a smaller environmental footprint than stores, which are all backed by warehouses anyway.

It's either a small amount of additional cardboard and plastic, or a whole additional building and a few miles of driving a single automobile. It's pretty clear that Amazon wins this comparison.

I’m not so sure that a local electronics shop is way more ecological. More HVAC, more lighting, items shipped to an intermediate warehouse, then reshipped, then maybe transferred between stores, then customers driving their SUVs around shopping.

It wouldn’t surprise me if Amazon can get me a TV with lower total emissions than if I shopped locally. If I comparison shopped locally, I’m virtually certain Amazon’d win.
