摘要：The main objective of this study was characterised by analysing the barriers associated with the insertion of sustainable practices in small and medium-sized companies in the metalworking sector, considering the Brazilian reality. Thirteen barriers were previously listed from the literature, and information about them was collected from 24 experienced managers who know the realities of small and medium-sized companies in the sector. Data were analysed using descriptive statistics. The frequency distribution showed that in each barrier, there was more than 50% of the responses allocated in the upper range, that is, medium or intense observation, demonstrating that SMEs experience many difficulties in this theme. When comparatively analysed via Fuzzy TOPSIS, difficulties associated with lack of knowledge and financial resources/incentives that can support SMEs in adopting sustainable practices are highlighted. The main contribution of this study is to provide robust information that company managers and other researchers can use. In addition, the provided information can support more complex debates for structuring public policies.
