The case at local and regional levels are well developed, but the discussion at international level seems poor, maybe the authors could exclude this mentioned focus o the Introduction I'll suggest a format review in the figures and their quotations, as well as the box and the table.
Following on the latter, my final point concerns the relation between transformative change and NSC. One the one hand, the paper trumpets collaboration, joint principles and responsibilities, mutual trust, etc. On the other, the paper also refers to vested (eg ‘carbon’) interests (38, 619), strong voters’ resistance (574), policy holdups (507) and opposition from disadvantaged groups (118). I would suggest the paper can delve deeper into the question of how the NSC can help to meet and overcome such resistances, and to bring forces of change and resistance more in line in the story.
