Leapfrogging is not just a developmental issue, it's also an environmental issue. As long as developing nations rely on greenhouse-gas-heavy power and industrial technologies, the worse off they'll be as they develop. We're already seeing this happen. Of the top six greenhouse gas producing countries, three are considered "developing" nations: China, at #2; India, at #5; and Brazil, at #6. Furthermore:
...between 1990 and 2000, energy-related carbon dioxide emissions grew by 69 percent in India, 57 percent in Brazil and 33 percent in China.
Argentina and the EU are crafting an agreement involving cash incentives and technology transfers to push the developing world towards sustainable energy and industrial technologies. Let's hope this assisted leapfrog plan works.
