In this article the authors develop and test a model that incorporates exte
rnal and internal antecedents and consequences of the integration of enviro
nmental issues in marketing. The external antecedents of green marketing in
clude consumer environmental sensitivity, competitive intensity and regulat
ory intensity. The internal antecedents consist of marketers' environmental
consciousness and business sensitivity towards environmentalism. The integ
ration of environmental issues in marketing is made manifest through the de
velopment and commercialisation of green products and the incorporation of
environmental issues in marketing communication. The consequences of this s
o-called green marketing are reflected in the performance of a business. Th
e model is tested on a sample of 138 Dutch manufacturing businesses using p
artial correlation analysis. The results indicate that environmental regula
tion is still the most important reason for marketers to adopt environmenta
lly friendly marketing programmes. The results further show that businesses
that voluntarily adopt green marketing are able to exploit green market op
portunities and improve their business performance.
