Abstract
This research aims to investigate the level of cluster approach adoption to support the environmental management of small and
medium enterprises and reduce their environmental impact. The research identifies the main phases of cluster approach
methodology and assesses the level of its adoption in 28 international case studies included in 5 different categories of cluster.
Our study carried out a comparative analysis between the experiences of each cluster category and the level of implementation of
the cluster approach methodology. The analysis shows the “distance” from the full cluster approach implementation and the case
studies broken down by category.
