These large-scale changes will have to be coordinated, at least informally if not tightly, among the major economies. Each should understand the basic directions of change that will be required at the national level and globally, and all nations must share in the deployment of new sustainable technologies and in the co-financing of global responsibilities, such as increased investments in African infrastructure.
这些大规模的改变需要在主要经济体中协调起来，这样的协调即使是不紧密的，至少也要是非正式的。每个经济体都应该明白在国内层面和国际层面需要的变化的基本方向，所有的国家都应该分享新型可持续 技术的应用，以及分担在诸如增加非洲基础设施投资的全球责任中的共同出资。
