While protocols appear to be the ultimate top-down mode of governance, having "scant provisions for public participation," it is widely thought that the influence of transnational networks has been growing Public opinion is relevant, as concern must exist to prompt action and dedication of government resources. It kept growing more and more since the young activist Greta Thunberg started Fridays for Future. Non-governmental organizations also fulfill certain roles, from gathering information and devising policies to mobilizing support. Science plays an important part, although Susskind asserts that sometimes this role is diminished by uncertainty, disagreement, and the rise of "adversary science."
