This toolkit provides governments with policy guidance across three areas – regulatory tools, financial tools, and information tools – to help SMEs in the ASEAN Member States enhance their environmental performance and economic competitiveness. In each of these three areas, approaches are highlighted that focus on supporting cost-effective measures that enhance competiveness. Chapter 3 of this report also provides a series of quick and digestible messages about the benefits of greener practices for both SMEs and for policy makers, and their respective roles in this process.
