Wendy, thank you for writing. I noticed that in yout comment you do not mention the need, overlooked even by the WCED 1987, to transition from pollution production economies to pollution-less economies such as the transition from environmental pollution production economies to environmentally clean economies, for which you need first to set up POLLUTION REDUCTION MARKETS LIKE GREEN MARKETS, which then can be driven towards environmental pollution-less markets by closing the renewable energy technology gap to make environmental pollution reduction A PROFIT MAKING OPPORTUNITY... None of the approaches you list there that have been advanced are based on pollution reduction market theory. which you can find in researchgate or academia now

I appreciate the comment.

Respectfully yours;

Lucio
