This policy brief introduces the Transnational Climate Impacts (TCI) Index, a framework developed by the Stockholm Environment Institute to measure country-level exposure to climate risks that cross national borders. The brief argues that globalization connects countries through biophysical, financial, human, and trade pathways, meaning that even wealthy nations with low direct physical vulnerability can be highly exposed to transnational climate risks. It recommends that the UNFCCC and national governments integrate these transnational dimensions into adaptation planning and finance to ensure global economic stability.

This report by the World Resources Institute examines Concentrating Solar Thermal power (CST) as a large-scale, zero-carbon alternative to coal-fired power generation. It highlights the role of thermal storage in providing baseload power and discusses the policy and economic barriers—such as high upfront capital costs and the need for carbon pricing—that must be addressed to accelerate global deployment, particularly in rapidly developing economies.

The research identifies 105 cities with populations over one million across 34 Global South countries suitable for electrification, based on electricity access (>90%) and carbon intensity (<600 tCO2e/GWh). While all South American cities meet these criteria, suitability is low in sub-Saharan Africa (3 of 40 cities) and South and East Asia (26 of 202 cities).

This report presents the first global, map-based indicator of potential threats to coral reefs, finding that 58% of the world's reefs are at risk. Southeast Asia is identified as the most threatened region, while the Pacific is the least. The primary drivers of degradation are overexploitation and coastal development. The report highlights a critical lack of adequate marine protected areas and calls for integrated coastal management to preserve biodiversity and the economic services reefs provide to nearly half a billion people.
