The impending climate crisis has raised expectations of companies green marketing, at the same time the digital development and the corona pandemic have shifted consumers buying behavior more towards companies’ e-commerce platforms. The underlying problem behind the study is that companies need to create green value that is perceived as real by their consumers and does not generate a negative effect or is misinterpreted for greenwash. Thus, it is important for companies to create real green value ​​for their consumers via their e-commerce platform that in the long run will contribute to profitability, competitiveness and a more environmentally friendly planet. The purpose of the study is to contribute to an increased understanding of how companies in the Swedish retail business can create and convey green value ​​for consumers via their e-commerce platform. The study uses a qualitative multi-case study where data is collected through interviews from five Swedish retail companies. The empirical data was analyzed through a theoretical framework based on the theories of Customer Value Proposition (CVP) and E-commerce Marketing Mix. The study finds that green value ​​should be combined with other more basic values ​​that are crucial for a purchasing decision, where the green value is then perceived as more real. It could also be stated that green value creation differs between companies because it is based on their customer group and the product categories they offer. Thereby, companies start from the consumer's subjective perception in order to understand how they should act in their value creation. Regarding the conveying of green value, it could be stated that companies' messages are perceived as more credible if they are transparent in their communication. Finally, the study presents three elements that companies should consider in their green value creation; (1) that green value ​​can become more autonomous and offer a direct effect that fills the consumer’s needs, (2) to educate and inform consumers to influence their subjective perception of the green value ​​and, (3) to be transparent to show how green value is created as well as what needs to be improved, thereby reducing greenwash.
