Delivery emissions should be attached to the person getting the delivery. Otherwise you could just skip most of your emissions by having everything delivered.
Either way, it changes your behavior, because if delivery is more expensive (to factor in the externalities it causes) you will either consume less, or pay more. This ultimately "attaches the emissions to the person getting the delivery" but in a far less complex and less game-able way.
If I order something off Amazon, do I get a say in where the package is shipped from to control "my" emissions.
Yes, you would have to use some of your carbon credits to pay for the delivery and manufacture of the shoe. The product would have both a monetary and a carbon price. If you don't have enough credits, then you can buy some on the spot market from someone who isn't using theirs up.
This would incentivise repair of the shoe, as it may require fewer carbon credits.
