Intergenerational justice is implicit in international commitments to susta
inability. If ecological, economic, and social components of sustainability
are to be achieved, there is a necessity for intergenerational justice con
siderations to be included in decision making. The present generation's ris
k judgments should include consideration of the possible outcomes for their
children. But intergenerational issues cannot be considered in isolation f
rom other current risk and fairness concerns. This article reports on a com
munity-based integative model that describes justice and other attitudes an
d motivations that determine community and individual proenvironmental beha
vior in two nations: Germany and Australia. This model can account for a co
nsiderable amount of the Variance in political compliance as well as variou
s proenvironmental behaviors. Group or individual self-interests have nearl
y no effects on global protective behavior. It is shown that universal as w
ell as contextual principles, including distributive (within or between gen
erations), procedural, and interactive justice, play a crucial role in fair
ness judgments. Other principles are also taken into account, such as effic
iency, environmental rights, and rights to economic welfare. The results ar
e discussed in relation to the importance of complex community fairness jud
gments in predicting and evaluating acceptance of political decisions, and
for promoting proenvironmental behavior.
