This paper extends previous environmental management research by building and empirically testing a model of the contingency effects of green advertising on the relationships between environmental management practices in terms of environmentally conscious manufacturing and product stewardship, environmental reputation and financial performance. We examine the value of green advertising in sharing and publicizing information about organizational achievements in environmental preservation in a business‐to business context with the Taiwanese electronics manufacturing industry. The theoretical propositions are largely confirmed by structural path analyses of survey responses collected from 122 Taiwanese electronics manufacturers. Green advertising delivers financial benefits only for those manufacturers that do not have an established environmental reputation. Copyright © 2013 John Wiley & Sons, Ltd and ERP Environment
