The Nature Conservancy: Sustainable Land Bonds - How governments can finance climate commitments and strengthen rural economies. Co-authored by ESS, March 2018. See: 

This report shows how tropical forest countries can tap mainstream bond markets and secure long-term capital at extremely low net cost through the issuance of Sustainable Land Bonds to finance the large-scale transition to sustainable and low carbon land management practices.

SLB financing can help countries achieve their Nationally Determined Contributions (NDCs) under the Paris Agreement while, at the same time, protecting the environmental infrastructure that supports rural production.

By doing this, governments can catalyze a virtuous cycle of inward investment, higher rural productivity and increased employment, as well as meeting their climate mitigation targets.

UN-REDD Programme: Lower the cost of financial capital to reduce exploitation of natural capital - a blog contribution by ESS, October 2014

There is a critical missing link in REDD+ thinking, and that relates to the high cost of finance for SMEs in developing countries, widely acknowledged to be the engines of economic growth. Yet SMEs face strong headwinds when it comes to accessing funding. For many SMEs, the unsustainable exploitation of natural resources – or “natural capital” – is a substitute for financial capital.

Forest Investment Review:  The Forest Investment Review was published in June 2009 by Forum for the Future.

Meeting the Climate Challenge: Using Public Funds to Leverage Private Investment in Developing Countries:  This Report was published in September 2009 and is the output of a public/private discussion coordinated by Lord Nicholas Stern, Chair of the Grantham Institute for Climate Change and the Environment at the London School of Economics. The main purpose of that discussion was to identify the most efficient instruments that Governments could use to leverage private finance and thereby enable sufficient financial flows to developing countries to achieve their mitigation and adaptation objectives. ESS contributed to Chapter four (pp30-41) which makes recommendations on how public finance can be used to stimulate private sector investment in reducing emissions from deforestation and degradation of forest land (REDD).
