Chapter 7 develops the idea that there are sufficient existing pro-public public banking functions (and resources) to synthesise what a democratised green & just public bank can and should look like. It does so to illustrate how public banks can be made to function in pro-public green & just ways otherwise impossible under the short-term, high-return regime of corporatised and private financiers. The proposal revolves around pursuing a Triple Bottom Line, or mandate, aimed at (1) a green & just transition, (2) financial sustainability, and (3) democratic decision-making.
