This comes from Congressmember Alexandria Ocasio-Cortez's plan for a Green New Deal, which will be tabled next year:
The Plan for a Green New Deal (and the draft legislation) shall recognize that innovative public and other financing structures are a crucial component in achieving and furthering the goals and guidelines relating to social, economic, racial, regional and gender-based justice and equality and cooperative and public ownership set forth in paragraphs (2)(A)(i) and (6)(B). The Plan (and the draft legislation) shall, accordingly, ensure that the majority of financing of the Plan shall be accomplished by the federal government, using a combination of the Federal Reserve, a new public bank or system of regional and specialized public banks, public venture funds and such other vehicles or structures that the select committee deems appropriate, in order to ensure that interest and other investment returns generated from public investments made in connection with the Plan will be returned to the treasury, reduce taxpayer burden and allow for more investment.
The part in italics (which I added) is, of course, pure Green Infrastructure Quantitative Easing.
I first explained this (including the multiplier effect) here, in 2010.
I explained it in more depth in 2015.
And now, I think, it's time is coming.
In a world where the biggest existential threat is global heating (warming is now in the past: heating is now what's happening) then Green QE is not radical. It's just plain common sense, whatever the opponents (who can always find money for wars and tax cuts) might say.
