Green purchasing can reduce negative environmental impacts as well as promote sustainable
development. As related literature from the African context is limited, this paper tries to bridge the
gap by investigating the green purchasing behaviors of residents in the Tamale Metropolitan area of
Ghana. The theory of planned behavior (TPB) served as a theoretical framework for identifying the
main antecedents of green purchasing behavior. Standard and hierarchical regression techniques
are used to analyze data gathered from 325 residents of the city. The results indicates that the TPB
variables explained 44.4% of the variance in green purchasing intentions, but only 13.2% of the
intentions are translated into actual behavior. Academically, this study has provided further evidence
for the application of the theory of planned behavior in explaining environmentally responsible
purchasing behaviors. Practically, this study has enhanced understanding of the antecedents of
green purchasing behaviors among the urban residents and has also provided useful information
which could aid in crafting suitable policies for a transition towards more sustainable consumption
patterns in a developing country.
