Building on recent applications in Latin America, this paper overviews WRI’s Green-Gray Assessment method, and provides recommendations for applications.
Sustainable Development Goal 9
Build resilient infrastructure, promote inclusive and sustainable industrialization, and foster innovation.
Greater investment in sustainable infrastructure is essential. Yet financing it is a challenge everywhere, especially in developing countries.
WRI research shows that that about $90 trillion in infrastructure funding will be needed by 2030 to achieve the goals of SDG 9. Ensuing this infrastructure is environmentally sustainable does not need to cost more and may even save money. The investment choices made by low- and middle-income countries in the next few years as they build cities, industries, and energy and transport systems could lead to a clean, climate-smart growth pathway or they could lock the world into a high-carbon, inefficient and unsustainable future.
To avoid the consequences of business-as-usual, WRI’s Finance Center, Energy Program, the New Climate Economy project and other programs work with governments and corporate leaders to guide investment choices in manufacturing, innovation, energy, urban environments and more. We share in-depth analyses, robust and timely data, and recommendations to move decision-makers toward resilient, low-carbon choices (SDG 9.1, SDG 9.2, SDG 9.4).
Green infrastructure can mitigate most of the world's major water problems, but investment has been held back by lack of certainty about returns. Our new methodology helps lay out how to measure the costs and benefits of green and gray infrastructure projects.
The Natural Infrastructure for Aquifer Recharge Financial Calculator, is an excel based tool with a flexible financial model that estimates the private costs and benefits, including the return on investment (ROI), of natural infrastructure interventions designed to enhance aquifer recharge. The technical note explains the methods, data and assumptions used to produce the tool.
Green infrastructure like forests, wetlands and coral reefs can help traditional “gray infrastructure” perform better. Yet, green-gray infrastructure projects remain relatively niche, mainly because of persistent myths about their costs and feasibility.
There is a strong and compelling environment and development case to be made for securing indigenous and community lands. Securing collective land rights offers a low-cost, high-reward investment for developing country governments and their partners to meet national development objectives and the 17 Sustainable Development Goals. Securing community lands is also a cost-effective climate mitigation measure for countries when compared to other carbon capture and storage approaches.
Indigenous and community lands, crucial for rural livelihoods, are typically held under informal customary arrangements.
