In the context of Strategy 2020 and in the follow-up to the United Nations Conference on Sustainable Development (Rio+20), ADB prepared the report Environment Operational Directions, 2013–2020. The report aims to provide a coherent overview of its environment operations and to articulate how it will step up efforts to help the region achieve a transition to environmentally sustainable growth or green growth. Building on ADB sector and thematic plans, this paper provides a brief review of recent ADB experience in environment operations, and identifies effective approaches for the development of “greener” country partnership strategies, investment projects, and associated knowledge and technical assistance activities. The paper is aligned with key elements of relevant ADB sector and thematic operational plans, particularly for sectors where environmental sustainability is a priority. These include the Sustainable Transport Initiative Operational Plan, the Urban Operational Plan, the Water Operational Plan, the Energy Policy, and the Sustainable Food Security Plan, as well as the Climate Change Strategic Priorities.
