PurposeFilling a gap in extant research regarding the measurement of an export country's environmental image and investigating its importance for consumers' evaluation of an environmentally differentiated imported product.Design/methodology/approachOnline surveys carried out in Denmark (Study 1), Germany and France (Study 2; N˜500 from each country). In Study 1, we develop an environmental country image instrument and investigate its nomological validity vis-à-vis other country image constructs and Danish consumers' evaluation of organic milk from Germany. In Study 2, we validate the instrument with consumers from Germany and France, evaluating organic milk from Denmark.FindingsConsumers differentiate between a country's environmental image and its general and production-related images. The country's environmental image is important to consumers' evaluation of an environmentally differentiated product from the country. Specifically, we find that a country's environmental image strongly influences its product-specific images and, through these, the consumer's evaluation of an organic food product from the country.Practical implicationsConsumers' use of a country's environmental image as a cue to the credibility of environmental claims gives competitive advantages to exporters from countries with a favorable environmental image, while exporters from countries with an unfavorable environmental image need measures to compensate. Companies and countries should monitor how the environmental image of their country evolves in important markets and be ready to act when facing damages to their country's environmental image.Originality/valueThis article is the first to propose a measure of environmental country image and to document that consumers use the environmental image of an exporting country to assess environmental claims on imported products.
