• This thesis investigates the impact of sustainability labels in advertisements of fashion brands on social media. It aims to answering the following research questions: Do consumers search for more information on sustainability labels? Do sustainability labels impact credibility? Do sustainability labels impact purchase decisions? To answer the research questions an online survey with 202 participants was conducted. The empirical study revealed that consumers tend to search for less additional information when a sustainability label is displayed in an advertisement on social media. Few consumers believe that brands are fully sustainable when sustainability claims in an advertisement are not supported by a sustainability label. The display of a sustainability label may not be one of the most important factors for consumers considering purchasing fashion items. Those results suggest that brands should use sustainability labels as an important tool in advertising on social media to fill the informational need of consumers and increase credibility.
