The term "dynamic carbon footprinting" can be used in at least three different ways, as if we needed more confusion.
- As opposed to static carbon footprinting, I think of dynamic carbon footprinting as a method that takes into account the time dimension. When certain emissions are generated is as important as the quantity of those emissions. The timing is critical in analyzing a whole range of carbon emission and sequestration processes: CO2 gradually absorbed over time by newly planted trees, natural systems (such as soil) and products (such as wooden furniture or building components) that sequester CO2 for limited periods, emissions generated throughout a long use-phase for a durable product (especially in comparison to the production emissions generated at the beginning), etc. [More on this in previous posts: 1 2 3]
Businesses operating in a carbon-constrained world may evaluate each other's carbon footprints in a continuous attempt to minimize overall carbon emissions in their value chains. For example, this could involve comparing the footprints of similar products made in different parts of the world while choosing global suppliers . The competitive dynamics involved in these emission reduction efforts have led to the term "dynamic carbon footprinting". [More]
The least interesting and unduly complicated use of the term has to do with displaying "dynamic carbon labels" for RFID tagged goods using NFC enabled mobile phones. The idea is that each "instance" of a product has a different footprint, because of differences in transport and storage emissions. A consumer could check the carbon footprint of a product on the store shelf using a mobile phone and get a number that is good for just that store. [More]
