The carbon footprint idea seems flawed to me. It always just depends how far you look. There are machines making machines making machines and so on, the chain is really long and those early machines in the chain, which may have been necessary to create given product, may not even exist anymore. They might have existed before the product was even invented.
Note that the whole idea was mostly popularized by BP [1][2].
