A systematic framework of indicators for sustainability is presented.
In our approach there is an emphasis on societal activities that affec
t nature and on the internal societal resource use, as opposed to envi
ronmental quality indicators. In this way the indicators may give a wa
rning signal to an unsustainable use of resources early in the chain f
rom causes in societal activities to environmental effects. The aim is
that these socio-ecological indicators shall serve as a tool in plann
ing and decision-making processes at various administrative levels in
society. The formulation of the indicators is made with respect to fou
r principles of sustainability, which lead to four complementary sets
of indicators. The first deals with the societal use of lithospheric m
aterial. The second deals with emissions of compounds produced in soci
ety. The third set of indicators concerns societal manipulation of nat
ure and the long-term productivity of ecosystems. Finally, the fourth
set deals with the efficiency of the internal societal resource use, w
hich includes indicators for a just distribution of resources.
