The World Bank and WRI have published a report called ""Integrating Green and Gray – Creating Next Generation Infrastructure" that aims to advance the integration of green and gray infrastructure solutions on the ground. Connecting with core themes in the Taskforce “Infra 3.0” concept paper, the report places a spotlight on the world’s growing infrastructure crisis, driven by climate change and growing populations. It proposes insights, solutions and examples for putting nature to work. It examines the technical, environmental, social and economic dimensions of a typical project assessment but also outlines, with new clarity and detail, the enabling conditions required to facilitate successful implementation of green-gray projects. Harnessing the collective analytical and technical expertise of the World Bank and WRI, it aims to build momentum in both policy and practice.
