1. United Nations Environment Programme Finance Initiative (2022): Diving Deep: Finance, Ocean Pollution and Coastal Resilience: Launched at The Economist World Ocean Summit, the guidance focuses on the problem of solid waste pollution—including plastics—and coastal infrastructure projects. It provides easy-to-follow recommendations on where to challenge companies to adopt clear sustainable practices, to avoid financial transactions with companies that have no sustainable transition plan in place and to seek out opportunities in ocean-related sectors where there is evidence of sustainable practice, for example designing product for reuse, repair, and recycling at end of life.

4. Sustainable financing and policy models for municipal composting
   Organic waste management can deliver big benefits to cities at a relatively low cost, but rates of composting is low in most cities. This report looks at the ways that cities can use composting to reduce municipal organic waste and provides good practice examples. The report is aimed at Global South cities but draws on experience from across the globe.

Analysing six case studies in Austria, Bangladesh, Brazil, Bangalore, Sri Lanka and Europe, the report outlines the strategies, financing mechanisms and policies that can create the right environment for a successful municipal composting project.
