Its also somewhat of a "lead by example" situation. Those most capable of implementing solutions should implement every solution they have and show how it can be done and then the rest of the world will follow or at least feel the pressure.
Rather than rich countries with citizens living the most resource intensive lifestyles possible judging people in poverty for not having better than first world waste treatment.
I really think that the « lead by example » thing is understated. Developed countries leading by example and demonstrating that sustainable development is profitable and successful is the only way to transform the current situation into a future in which the « polluting stage of development » is understood as being only a transient phase of development and not an end state.
