The report argues that Concentrating Solar Thermal power (CST) is a viable large-scale, zero-carbon alternative to coal-fired power, particularly when combined with thermal storage to meet baseload demand. While currently more expensive than coal, costs are expected to decline through technology learning, R&D in materials and optical design, and economies of scale from larger plants. The document highlights that a carbon price of approximately $115 per ton of CO2 would make CST with 6 hours of storage economically competitive with coal. It emphasizes the need for stable policy support, such as feed-in tariffs, to bridge the current cost gap and calls for increased deployment in rapidly developing economies like China and India to alter their emissions trajectories. Additionally, the report notes that widespread CST adoption requires improved transmission infrastructure, specifically federal coordination in the U.S. and links between the EU and North Africa.

The analysis identifies 105 cities with populations over one million across 34 Global South countries where electrification is currently a viable low-carbon strategy. Suitability is determined by a minimum 90 percent urban electricity access rate and a carbon intensity of electricity supply below 600 tCO2e/GWh. While all South American cities meet these criteria, suitability is significantly lower in sub-Saharan Africa (3 out of 40 cities) and South and East Asia (26 out of 202 cities).

Groundwater is the most abundant freshwater source, supporting 40% of irrigated crop production and over 25% of the global population's drinking water. However, it is being consumed at unsustainable rates, with 20% of river basins currently overdrafted and over 50% at risk by 2050. Over-extraction leads to saltwater intrusion, dried-up wells, and land subsidence. Sustainable management requires measuring extraction, setting volumetric caps, and implementing natural or managed recharge solutions, as demonstrated by the Edwards Aquifer in Texas.
