This chapter looks at the institutional structures that EaP countries need to establish in order to support the greening of SMEs. It begins with a discussion of the need to build the capacity of government actors, especially local and regional government administrations, to help signpost SMEs to where they can get appropriate resources and information (if it is not available at the local level). The role of national environmental authorities in overall co-ordination of efforts to promote green activity of SMEs is also noted. The chapter then discusses the vital place of trade associations and other industry groups in supporting greening efforts, as they are most likely to have effective communication channels with both their members and government authorities. Finally, the chapter addresses the potential role of financial advisors such as accountants, banks and insurance companies. SMEs are regularly in contact with them, and they are a trusted source of information; they could potentially increase awareness of changes to environmental requirements as well as sources for further information.
