UNEP FI works closely with over 200 financial institutions that are signatories to the UNEP FI Statement on Sustainable Development, and a range of partner organisations, to develop and promote linkages between sustainability and financial performance. Through peer-to-peer networks, research and training, UNEP FI carries out its mission to identify, promote and realise the adoption of best environmental and sustainability practice at all levels of financial institution operations. Global Footprint Network Global Footprint Network is an international think tank working to advance sustainability through the use of the Ecological Footprint, a resource accounting tool that measures how much nature we have, how much we use and who uses what. Global Footprint Network coordinates research, develops methodological standards and releases annual data on the Ecological Footprint and biocapacity of 232 countries and humanity as a whole. By providing robust resource accounts to track the supply of and demand on ecological assets, Global Footprint Network equips decision-makers with the data they need to succeed in a world facing tightening ecological constraints.

Key Messages Sovereign bonds represent over 40 per cent of This report addresses how and why natural the global bond market, and are therefore one resource and environmental risks are becoming of the most important asset classes held by financially material for sovereign credit risk, investors around the world. At the end of 2010, not just in the medium term, but even in the outstanding sovereign debt was equal to USD 41 short run. The E-RISC (Environmental Risk trillion. Sovereign bonds have traditionally been in Sovereign Credit analysis) methodology considered a reliable and risk-free investment focuses on the development of metrics and of choice by fund managers. Since 2008, this methods for quantifying natural resource and perception is being increasingly challenged. environmental risks so they can be incorporated into sovereign credit risk assessments. A growing group of investors is recognising the This initiative focused on one key piece: to need for a broader understanding of emerging demonstrate the potential materiality of natural risks in the bond markets. Furthermore, there resource and environmental risks in the context is growing concern over the mounting threat of of sovereign credit risk analysis, which can systemic risks outside of the financial system, affect the underlying value of sovereign bonds. notably environmental risk, which can impact multiple financial markets. The methodology relies on the Ecological Footprint and biocapacity metrics to assess Natural resources, both renewable, biological a country’s resource situation in order to resources such as food and fiber, and non- identify how these risks might affect sovereign renewable resources such as fossil fuels, credit risk. The traditional focus on renewable ores and minerals, are critical to each nation’s biological resources by Global Footprint economy. Yet, to date, risks stemming from Network (such as fisheries, forests, cropland renewable resources in particular are not and grazing land) is supplemented with data well considered in sovereign credit risk on non-renewable natural resources including assessments. As resource constraints tighten fossil fuels, metals and minerals to provide globally, countries that depend, in net terms, a more comprehensive definition of natural on levels of renewable natural resources and resources. services beyond what their own ecosystems can provide may experience profound economic The method and metrics developed in the impacts as resources become more unreliable E-RISC project lay the foundations for enhanced or costly. analytics that can account for the growing materiality of natural resource constraints for Traditional sovereign credit risk analysis sovereign credit risk. appears to inadequately reflect pressures from increasing global natural resource scarcity, environmental degradation and vulnerability to climate change impacts. Five countries – Brazil, France, India, Japan and Results of the E-RISC project show risks Turkey – were analysed, based on consultations related to natural resource constraints and with the participating financial institutions.
