The Bali negotiations will succeed if the world keeps its eye on supporting the speedy adoption of low-emissions technologies in power, automobiles, heating, and carbon sequestration. We could waste years discussing who is to blame and who is to pay for emissions control. We could endlessly debate the merits of alternative control measures such as tradable permits, taxes, and industrial standards. Yet issues of blame, costs and choice of control mechanisms are less important than rapid technological development and deployment, backed by some form of control mechanism chosen by each country.
If the less polluting technologies pan out at low cost, the rich countries will be able to afford to clean up their own act while also helping the poor make the needed conversions. Climate control is not a morality play. It is mainly a practical and solvable technological challenge, which if met correctly, can be combined with the needs and aspirations for a growing global economy.
