This article intends to show the results of the review of literature of studies of emerging environmental sustainability practices in micro, small and medium enterprises (MSMEs) in the last five years (2010)(2011)(2012)(2013)(2014)(2015) . The method used to review and evaluate the literature was based on the seven-step synthesis for research: problem formulation, literature search, obtaining information of studies assessing the quality of studies, analysis and integration results, interpretation of evidence and presentation of results. We evaluated 16 studies from 15 different countries, with a sample of more than 300 different companies. The findings suggest the existence of at least five emerging practices that promote environmental sustainability in MSMEs.
