The concept of lean has been studied and proven to be an effective philosophy to eliminate waste, resulting in operational gains and improvements across the whole supply chain. However, nowadays that is not enough for an organization to be competitive only in terms of economic aspects, but also to be competitive from environmental and social points of view. This impacts the whole supply chain, especially on the supplier selection and therefore, this dissertation aims to understand the link between lean and sustainability and what are the criteria used to determine a lean sustainable supplier. Hence, a systematic literature review (SLR) was carried out, along with a bibliometric analysis of lean and sustainability relationship using the platform Web of Science from 2010 to 2021. Furthermore, a map was drawn to observe an underlying intellectual structure based on the collected data using NVIVO software. An online survey was used as the research methodology and a conceptual framework to assess the level of lean and sustainability of a supplier was proposed. Through factor analysis, the results obtained suggest that there is a strong correlation among lean and sustainability given a good global adjustment fit among latent variables. Moreover, the local adjustment displayed a mediocre fit since three out of six dimensions showed good reliability and validity among latent and manifest variables. In the end, the factor loading between lean and sustainability in 0,964 in which validates the conceptual framework.
