How social networks influence the dissemination of cleaner technologies to SMEs

In their decisions to adopt cleaner technologies, small and medium-sized enterprises (SMEs) are strongly influenced by organisations like suppliers, customers and local authorities. This paper analyses how these network relationships influence the dissemination of cleaner technologies to SMEs. A case-study in the Dutch anodising industry shows that in this sector, the competitive nature of the anodising supplier industries and the dependence on customers are major barriers to the uptake of cleaner technologies, which financial help or emission regulations are unlikely to overcome. Two network strategies are proposed to overcome these barriers: involving third parties to stimulate interaction between anodising firms and their clients on environmental issues, and the implementation of pilot projects which are tied into follow-up programmes.
