The document examines how different financial instruments and institutions define and calculate 'leverage'—the ability of public funds to catalyze additional investment. It finds that leverage is often conflated with co-financing and varies wildly by instrument, making cross-comparison nearly impossible. The authors propose a new framework based on counterfactuals, risk mitigation, and the avoidance of double counting to improve the rigor of climate finance reporting.

The document provides a comprehensive survey of quantitative research on the health impacts of climate change, categorizing studies by their methodological approach (primary, secondary, and comparative risk assessments) and the statistical models employed (time-series, non-parametric, and panel/spatial models). It highlights the complex relationship between climatic variables and diseases, particularly malaria, and reviews major global reports from the WHO and the Stern Review to outline the broader economic and public health implications of global warming.

The GSI has developed a manual of subsidy estimation methodologies based on the WTO's Agreement on Subsidies and Countervailing Measures to provide a foundation for internationally-agreed best practices and consistent data for subsidy reform.

The report provides a comprehensive survey of subsurface characterization technologies for superhot rock (SHR) geothermal systems, defined by temperatures above 374°C. It categorizes methods by spatial scale: exploration (100s-10s km), reservoir (10s-1 km), and monitoring (1 km-1 m). Key findings highlight that while many geophysical tools are mature, they lack validation in SHR-specific environments. The authors emphasize the need for integrated data analysis, such as joint inversion and machine learning, to reduce exploration risk and improve the accuracy of temperature and stress models. The report concludes that advancing SHR energy requires standardized data sharing, increased investment in high-temperature sensors, and the development of SHR-specific play fairway analyses.
