The research evaluates the impact of AI on the detectability of SSBNs, finding that AI enhancements are most effective in shallow waters (0-200 ft). This creates asymmetric strategic risks: the US enjoys a geographic advantage with direct deep-water access, while Russia and China's reliance on 'bastion' strategies is reinforced by AI's ability to secure shallow perimeters. The UK and France are identified as particularly vulnerable during the transit phase from port to deep ocean. While AI improves the 'Search' and 'Classify' phases of the detection chain, the authors conclude that fundamental physics and the cost asymmetry between seeking and hiding prevent the realization of 'transparent oceans,' though the perception of such a shift could destabilize nuclear strategic stability.

The briefing highlights the bipartisan support and technological advancements, particularly in Enhanced Geothermal Systems (EGS), that are driving geothermal growth in the U.S. It notes that 1.16 GW of capacity is expected by 2028 and that the Trump administration's policies, including permitting exclusions and support from Energy Secretary Chris Wright, favor the sector. However, the author argues that geothermal cannot replace wind and solar, which are necessary to meet a projected 128 GW increase in demand by 2030.

The report analyzes the environmental, health, and economic impacts of medium- and heavy-duty vehicle (MHDV) pollution in the US and advocates for an accelerated transition to battery-electric trucks. It highlights that while MHDVs make up a small fraction of road vehicles, they contribute a disproportionate share of NOx, PM2.5, and greenhouse gas emissions. The document argues that battery-electric vehicles (BETs) are technically and economically superior to hydrogen fuel-cell alternatives for most duty cycles. It details the role of state policies like California's Advanced Clean Trucks (ACT) regulation and federal investments from the Inflation Reduction Act (IRA) in driving adoption. The report concludes with recommendations for expanding charging infrastructure, implementing indirect source rules for warehouses, and maintaining high-road labor standards during the transition.

Brazil is positioned as a potential global leader in green steel due to high-quality iron ore and vast renewable energy resources, though its industry remains heavily reliant on coal-based blast furnaces. While the country leads in biochar use, a full transition requires shifting to electric arc furnaces (EAF) and green hydrogen-based direct reduced iron (DRI). The report emphasizes that strategic policy and the upcoming COP30 summit are critical to overcoming the longevity of existing coal-based infrastructure and the high capital costs of new technologies.

The document warns investors against chemical recycling due to high energy intensity and technical failures, while recommending separate collection (specifically reverse vending machines) and reuse-and-refill systems as high-growth, low-risk opportunities driven by regulatory shifts and consumer demand.
