This research study was inspired by the partnership between the Environment and Animal Society of Taiwan, a local NGO, and Carrefour to promote the welfare of hens, support small farmers, and boost food safety for the consumers. Through a qualitative single-case study approach, this research aims to describe Carrefour Taiwan’s CSR commitment to the cage-free eggs social initiative and identify the added value from the integration of the SDGs. Unstructured in-depth interviews with the CSR Director, online articles, literature review, and materials from EAST were analyzed to address the main purpose of the study. With a clear and central corporate mission to lead global food transition, Carrefour was able to integrate the relevant SDGs in its business strategy and further into its CSR programs. Carrefour’s partnership with EAST plays a vital role in the effectiveness of its cage-free campaign. The application of social innovation in its business model to support the cage-free eggs initiative has captured the attention of the retail industry, media, government, and consumers. Carrefour Taiwan’s commitment to supporting the cage-free eggs campaign has not only allowed it to mitigate risk from food-related scandals that pose a major threat to food companies’ reputation, but it has also strengthened the company’s reputation among its stakeholders. In addition, Carrefour was able to differentiate its brand from its competitors and thus gain a competitive advantage.
