This gets even more true when you start talking about the developing world. I'm sure Africans are going to stay poor to help deal with a problem largely created by the Europeans and Americans that have been abusing that continent for centuries. There is not a "fuck you" big enough.
I call the approach in this article "abstinence-based environmental solutions" by analogy with "abstinence-based" sex education, and it will be about as successful as trying to shame teenagers into not having sex.
This approach to sex education results teens hiding their sexuality, not using condoms or birth control, and getting more STDs and teen pregnancies. The analogous approach to fixing environmental problems will get us a lot of fake "greenwashing" and a continuation of the current CO2 growth trajectory.
Attempting to force austerity on us will result in a massive populist backlash and the election (or installation) of explicitly anti-environmental quasi-fascist or economic libertarian leaders.
