The document addresses the investment gap for climate-smart infrastructure in developing countries, where high perceived risks lead to high risk premiums and non-bankable projects. It defines de-risking as the reallocation or reduction of risk through policy measures (establishing rules and mandates) and financial measures (using public capital to bear risk). Three examples illustrate these mechanisms: the Green Climate Fund's anchor equity in Chile's Espejo de Tarapacá project, the Africa Energy Guarantee Facility's multi-layered insurance chain, and Climate Investor Two's tiered tranche structure. The guide concludes that while not applicable to all projects, strategic de-risking leverages small amounts of public capital to mobilize large-scale private investment.

The document clarifies that in science, uncertainty refers to the degree to which something is known rather than a complete lack of knowledge. It explains that climate scientists use specific probabilistic language—such as 'very likely' to denote a greater than 90 percent chance—to inform public policy and decision-making. While certain facts are established without uncertainty, such as the role of fossil fuels and the greenhouse effect in warming the Earth, uncertainties remain regarding the exact magnitude of future warming and the timing of specific ecological losses, often depending on future human actions to reduce emissions.

The document defines key maritime zones under UNCLOS, the roles of different states in fisheries management, and technical terms related to overcapacity, overfishing, and Maximum Sustainable Yield (MSY). It also highlights the impact of different types of fisheries subsidies on stock sustainability.
