Strengthening environmental governance and development of sustainable environmental policies plays an important role in the achievement of many of the Sustainable Development Goals. Countries of South-East Europe are undertaking the SDG nationalization process, and although some progress has been achieved with the integration of environmental requirements into sector-specific policies, much more needs to be done to enhance the environmental dimension of sectoral policies and ensure implementation and enforcement of environment-related provisions in sectoral policies and legislation. This project supports five countries in formulating actions on the basis of their Environmental Performance Reviews in order to achieve relevant SDGs. The project assists national stakeholders, in particular the ministries responsible for environmental issues, to contribute to the revision of sector-specific and cross-sectoral strategies aligning them with the SDGs. This is achieved by building the national capacities to assess priority needs in environmental governance and facilitating the national action to integrate evidence-based environmental policies into sector-specific and cross-sectoral strategies aimed at the achievement of SDGs.
