Carbon model for buying second-hand #172

Buying perfectly good second-hand goods instead of brand new is a very good way to campaign against the unsustainable consumerism society we live in.

In France, several websites exist for facilitating second-hand transactions, such as Leboncoin or Vinted (mainly for clothes).

The type of a good exchanged in a given transaction could be analysed and the carbon footprint induced by the fabrication of that good could be viewed as a negative carbon footprint.

The carbon model could be a simple mapping from generic types of good (e.g. pants, shoes, vacuum cleaner, mirror) to the environmental cost associated with their manufacturing.

This is an interesting thought. I don't think this should be counted as a negative carbon footprint, but there could be an idea of decay, as the models are Life-cycle based. A simple model would just allow you to say that it's been pre-owned and we discount the carbon model by 2. We haven't even really started on carbon models for individual items, but let's keep this in mind for later.
