The greening of economic growth series ESCAP, its partners and Asia-Pacific countries have advocated "green growth" as a strategy to achieve sustainable development in the resource-constrained, high-poverty context of the Asian and the Pacific region. The conventional "grow now, clean up later" approaches to economic growth are increasingly placing the futures of regional economies and societies at risk. The forward-thinking policymaker is tasked to promote development based on eco-efficient economic growth and at the same time, record more inclusive gains in human welfare and socio-economic progress. In order to assist policymakers in responding to such challenges, ESCAP’s activity on green growth has been developed to focus on five paths: sustainable infrastructure development; investment in natural capital; green tax and budget reform; sustainable consumption and production; and the greening of business and markets. The ESCAP “Greening of economic growth” series provides policymakers with quick access to clear, easy-to-read guidance to specific "green growth" policy tools and actions. This publication, Eco-efficiency Indicators: Measuring Resource-Use Efficiency and the Impact of Economic Activities on the Environment, is produced as an output of an ESCAP project entitled “Pursuing Green Growth by improving eco-efficiency of economic growth in Asia and the Pacific” under the Korea-ESCAP Cooperation Fund.
