As organizations seek to communicate with consumers who are concerned
about the environment, advertisements containing environmental claims
are becoming more prominent. While much has been written about environ
mental advertising, this phenomenon has seldom been examined systemati
cally. This paper presents an empirical study which combines two class
ification schemes to create a matrix that identifies different types o
f environmental claims and the likelihood that such claims will be jud
ged as misleading and/or deceptive. Results suggest that those claims
which extol the environmental benefits of products and those that are
designed to enhance the environmental image of an organization are mos
t prone to be considered misleading and/or deceptive. Methods for impr
oving environmental advertising are suggested.
