In 2016, it is no longer possible to deny the existence of global warming and its harmful effects on our planet and the environment. Not only experts, but also consumers, have become increasingly concerned about the environment. This increased awareness and concern has increased consumers’ interest in purchasing environmentally friendly food products, and has caused companies to focus on programs intent on reducing their environmental impact and helping the environment. Companies have introduced more environmentally friendly food products, accessible on a large scale, and have changed their communication to focus more on green products and green product attributes. Scandinavian countries have some of the largest numbers of organic food consumers in Europe and the world, with the Swedish organic food industry measuring the highest growth rate in organic food sales in 2015. Therefore, this study focuses on the Swedish green food industry. A major way for companies to make consumers aware of their available environmentally friendly food products is through green advertising. An increasingly frequent problem, however, is that consumers tend to distrust these green ads. They have knowledge of green washing practices and misleading information in green advertising. In this thesis, the relationships between green consumerism, green washing and green advertising skepticism were investigated. The potential relationship between demographic factors such as gender, age, income and level and area of study, and green advertising skepticism were tested as well. A research model with three main hypotheses was used in this thesis. The results showed a significant relationship between green consumerism and green advertising skepticism when green washing was a moderator. There was also a significant negative relationship between attitude towards green products and green advertising skepticism and a positive relationship between environmental concern and green advertising skepticism. There existed no significant relationship between the tested demographic factors and green advertising skepticism in the Swedish green food industry.
