N. Linn et al., TOWARD A SUSTAINABLE SOCIETY - WASTE MINIMIZATION THROUGH ENVIRONMENTALLY CONSCIOUS CONSUMING, Journal of applied social psychology, 24(17), 1994, pp. 1550-1572
The experiment was an educational intervention that promoted and descr
ibed an ongoing environmental tagging program located in a chain of th
ree local grocery stores. Model Community, a nonprofit community organ
ization, originated the environmental product tagging program that was
present throughout the experimental educational intervention and was
also responsible for sponsoring educational efforts in the local eleme
ntary schools and in the media. Over the period of a year, the experim
ental intervention was expected to stimulate self-reported environment
ally conscious consuming above the level generated by the tagging prog
ram alone and above the levels reported by shoppers who did not shop a
t the experimental stores. Environmentally conscious consuming or prec
ycling implies buying products packaged in recyclable materials, buyin
g least waste packaged (bulk or minimally packaged) products, and buyi
ng ''safer earth'' (nontoxic or alternatives to harsh chemicals) produ
cts. Contrary to expectations, there was no significant interaction ef
fect of year (preintervention vs. postintervention) and group (experim
ental store vs. control group) on self-reported environmentally friend
ly consuming, implying that the experimental educational intervention
did not have an effect. An investigation of the significant main effec
t of shopping at the environmentally tagged stores showed a significan
t positive effect on purchasing less toxic products, knowledge about M
odel Community, and awareness of the environmental tagging program. An
examination of more aggressive educational campaigns in future studie
s is warranted because of more overall positive (although not signific
ant) environmental shopping behaviors reported in 1990, when there was
an active education program for Model Community, than in 1991, when t
he program ceased.
