The thesis is about Green Marketing and Competitive Advantage: A Case Study of Eco-Friendly Products in South-South Nigeria. In recent times, there has been a lot of harm done to our environment, and people are now forced to rethink their actions. consumers are now forced to lean towards eco-friendly products, and businesses are now looking to turn green as a way to cause less harm to the environment. By doing this, they now have a sustainable competitive advantage over competitors. According to my research there is a gap between the attitude and behaviour of the consumers, regarding green products, as some people are aware of the harm done to the environment but still will not consider green products due to other factors that are covered in the research study. I strongly recommend that companies educate the public about their products, as most people are not aware of the reason behind green marketing.
