I was thinking more along the lines of forced behavior modifications such as reducing the number of children. Too many cultures and religions are all about making more and more babies. And while you might convince Western cultures in the need for infrastructure work, developing nations tend to demand their own period of industrial revolution where they can pollute and poison the Earth and there people. Forcing them to use more expensive green methods will be considered very totalitarian. To change things globally will require global participation.
Population is expected to decline on it's own due to improving lifestyles and access to healthcare. Most women don't want to be breeding factories.
If we can stop the industrialized nations from polluting then the developing countries will be able to develop without significant additions to the problem. Especially if there is a working green alternative to build up to. Plus, most developing nations are already feeling the crunch of climate change and are not as oblivious to the problem as comfortable developed nations are, they already want to go green and choose it whenever they have the option. Solar power is already a major player in Africa, where it powers most rural communities.
More and more Africa is pumping oil to sell to us while building a green power grid for it's own use.
There are also major power projects in the works to sell green electricity to European markets... DESERTEC has a goal to provide 15% of Europe's electricity by 2050 and provide power to the local communities.
Certain developed nations like to use the specter of developing nations to avoid action, but it's just an excuse. While our century old infrastructure crumbles due to complacency the developing world is building to surpass us in the next few decades.
It's sad when a single storm system can leave large sections of the USA without electricity sometimes for more than a week at a time... and that this now happens almost annually.
