How is it a problem to better understand which solutions are more effective than specific others? None are perfect, true. But the first line says there's no magic bullet. The point of this article, and I guess the book, is not to directly change specific behaviours, rather to educate about system thinking. Certainly, I had never heard of the Kigali accord and went away (presumably) better informed about the impact of refrigerants on greenhouse gases. The perfect need not get in the way of the good.
