While this chapter has examined a wide range of promising green growth policies, it would be premature to claim that a comprehensive list of best practices has been identified.
The available evidence suggests that there has been significant policy experimentation in both developing and developed countries, which highlights potential growth policy options. There has, however, been relatively little comprehensive analysis of the effectiveness, efficiency, and robustness of these policy options, under a range of political, economic, and social conditions. A major conclusion of this chapter, therefore, is that governments and their policy analysts need to address this significant gap in information.
This is especially true for analysis of policy portfolios. One of the difficulties in analyzing policy portfolios stems from the issue of attribution—which of the policy portfolio parts is responsible for the greatest change. Accordingly, increased research is needed on natural policy experiments, where differing combinations of similar policies have been applied under varying enabling conditions.
It is also important to conduct deeper research on specific types of policies that can drive green growth transformation. This includes further assessment of the conditions under which countries should pursue policies designed to support breakthrough innovations in technologies and business models versus supporting more incremental innovations and adaptations of existing technologies. In addition, a more extensive understanding is required for the policies and measures that improve skills of new and existing workers and ease the transition to new green industries for displaced employees. Governments and other practitioners would also benefit from more detailed analysis of sector level green growth policies that will achieve the greatest impacts in reducing poverty and achieving social inclusion, while advancing green development objectives.
