This toolkit, based on existing good practice, aims to help governments in the EU’s Eastern Partnership (EaP) countries (Armenia, Azerbaijan, Belarus, Georgia, Moldova and Ukraine) to design and implement key instruments to promote environmental compliance and green business practices among small and medium-sized enterprises. Reducing the environmental impact of SMEs in both manufacturing and services is a key success factor in greening the economy. At the same time, improving environmental performance is a significant business opportunity for SMEs as important suppliers of goods and services. Developed under the EaP GREEN project, this report will be of interest to environmental and economic ministries, as well as business associations and non-governmental and academic institutions in EaP countries.
