Many of the above resources are quite technical, and may appear to complicate a quite simple concept. Do we need to know exactly what the assumptions are behind a carbon footprint, as long as it is produced on a basis that allows comparison and action? Or is there a danger that a simple footprint can be twisted to allow vested interests to start making ‘greenwash’ claims?
