Returns packaging bonanza

I recently filled in an online request to return my iPhone headphones for a replacement. Apple quickly sent a jiffy-bag containing return instructions, the replacement headphones, an envelope to put the defective headphones into, and a pre-paid return envelope.

For a company that seems to be taking steps to focus on the environmental impact of their products, as can be seen in the Environmental Status Report of the iPhone Tech Specs, the size of the pre-paid envelope is absurd.
