Abstract (eng)
An increasing awareness of environmental issues such as climate change and environmental pollution is causing consumers to reflect on their own buying behavior. Green consumers are not only addressed by emotional advertising subjects, but also expect additional information about the advertised product to be provided.
The objective of this research paper was to explore the impact of green advertising, taking into account the personal green involvement and green consumer knowledge. For that purpose an experimental study was designed. In the course of this, also the perception of a possible virtual nature experience was questioned, respectively, whereby it is favored. In view of these requirements, a fictional advertisement for green clothing was created, which was varied in terms of image (nature image / neutral image) and claim (health claim / environmental claim).
To test the hypotheses, a 2x2 factorial design experiment was carried out with a sample of 176 German-speaking persons with a relatively high level of education. Findings showed that the claim effectiveness depends on consumers’ environmental involvement, which can be measured by environmental concern, attitude toward green products and green purchase behaviour. Concerning people with strong green involvement, a better claim effectiveness also leads to a better brand rating. Also with regard to the intention to buy green products, the claim effectiveness is essentially moderated by the green involvement of the recipients. Limits of the study concerned Virtual Nature Experience and green knowledge.
There was a tendency for some combinations of image and claim to be perceived differently by people with high green involvement and those with low green involvement. For future research, it is therefore recommended that the advertising impact of different image-claim combinations on differently-involved green consumers be highlighted in more detail, in order to tailor green advertising subjects to the target group.
