Powering the New Champions: How Green Can US$ 20 Trillion Be? The International Energy Agency (IEA) forecasts that US$ 20 trillion in new investment is required to meet world energy needs by 2030. Much of this investment is required in the world's fastest-growing economies and expectations for China alone amount to 18% of the total. Innovative policies and technologies present significant opportunities to ensure economic growth and social development while minimizing the unintended costs of investments such as urban air pollution, resource depletion, health damage, water stress and climate change. 1) How can fast-growing economies realize and deploy domestic innovation and clean technology breakthroughs? 2) How can a focus on enhanced energy efficiency and demand-side management enable sustainable growth in these countries? 3) What are the practical, most cost-effective ways to reduce carbon emissions across various sectors, and how can these be scaled up in the context of a carbon constrained world?
