Reviewer 1 Report

is necessary to explain the connection between the research topic and focus of the journal in the sections of Abstract, Introduction, and Conclusion

also I would recommend to add recent studies (2019-2020)

Reviewer 2 Report

The paper is very well written. I have several recommendations/issues.

There is no research hypothesis constructed and empirically tested in this paper. It will be more rigorous if research hypotheses are constructed from theories and/or existing literature.

The authors should put more emphasis on discussing their data. What is special in the choosing 29 OECD and nine non-OECD countries? Why not all OECD countries?

Conclusion part seems too weak according to the rich empirical results. As mentioned, research objectives clarified could help here with emphasizing most important implications and revealing the contribution of this research to the scientific knowledge.  

Directions for future research are missing in the end of this manuscript. It should be supplemented.

There are no references to the Sustainability journal. This makes me think that the paper is not necessarily related to the scope of the journal.
