The present work had as objective to investigate the effects brought by the 4C standard for Brazilian coffee agriculture. More specifically, analyze what types of improvements (upgradings) brought to producers that adopt the 4C standard. Improvements can be classified as economic, social and environmental. For this, a qualitative methodological approach of case studies was used. The first stage of the research corresponded to a systematic literature review, in which it was possible at the end to formulate the propositions. Interviews were then conducted with various agents within the coffee value chain-meso-institutions, cooperatives and producers. Through interviews, document analysis and articles published in specialized journals and journals, data were collected that were analyzed using the qualitative analysis software Atlas TI. The results indicate that most of the improvements can be characterized as environmental upgrading. In addition, the results show that the adoption of the 4C standard made farmers better organize their production processes and have more control of activities related to 4C coffee cultivation.
