A de-linking of pollution from economic growth and de-materialisation can p
robably be seen as the most important single characteristic of sustainable
development. With regard to this, ecological transparency means understandi
ng all human activities, processes and patterns that have an impact on the
potential for sustainable development. Closely linked with this is the idea
that the ecological footprint of the information society should be concern
ed with the environmental implications of its generations, applications and
the disposability of information and communication technologies (ICTs). Th
is paper aims at developing scenarios, and a set of criteria, plus indicato
rs as tools for identifying various environmental impacts inherent in the i
nformation society. Furthermore, it aims for the successful unification of
the positive factors of the information society with ecologically sustainab
le development. It is concluded that policy plans for the information socie
ty would benefit from the enhanced level of ecological transparency the inf
ormation society can provide, as presented via the indicators mentioned lat
er in the text. Further, it is suggested that prerequisites should be creat
ed for evaluating the implications of the information society and for the a
pplication of related information society technologies. Such an approach co
uld be labelled an Information Society Assessment. (C) 2001 Elsevier Scienc
