Kenya’s E-Mobility Knowledge Roadmap: Research Priorities to Support Economic and System Transformation

Kenya’s e-mobility transition is often discussed through a relatively narrow lens focused on vehicle adoption, charging infrastructure, and the fiscal implications of declining fuel tax revenues. The consultations that informed this knowledge roadmap pointed to a much broader opportunity.

From Fragmentation to Coordinated Action: Building a US Resilience Finance System

Communities across the country are losing ground to floods, fires, heat, and storms. Insufficient resilience investment is often framed as a simple shortage of money; however, there is existing capital across federal agencies, state programs, pension funds, philanthropy, community lenders, and private infrastructure investors. Better coordination is needed, not just access to funding. On April 20, 2026, Duke University and the Milken Institute brought together more than 40 senior practitioners—from green banks, infrastructure investment, commercial finance, think tanks, academia, housing and community development finance, local and state government, climate adaptation and resilience organizations, and international development—to examine what financial infrastructure is needed so that capital consistently reaches the communities and projects that need it.

Heat Legislation in California: Gaps, Innovations, and Opportunities

This report examines California’s legislative record on extreme heat from 2014 through 2025. During this period, California introduced 128 bills addressing extreme heat mitigation and adaptation, of which 57 passed—a passage rate of approximately 45%. California has also committed funding at a scale no other state has approached, treating heat as a comprehensive public investment rather than a narrow regulatory problem.

What Is the Future of Grid Utilization and Energy Affordability in Virginia?

The publication summarizes high-level takeaways from a working session about implementing Virginia's new grid utilization law (HB 434/SB 621), which aims to lower energy costs by better using existing infrastructure. Participants in the convening—organized by Deploy Action Labs and Duke's Nicholas Institute for Energy, Environment & Sustainability and moderated by Tim Profeta—included private sector leaders, advocates, researchers, regulators, and legislative staff.

When Centroids Mislead: Quantifying the Consequences of Sub-Optimally Aggregating Gridded Raster Data to Polygons

Point data, such as population, disease incidence, and greenhouse gas emissions, are commonly aggregated to a uniform grid of raster data for storage and representation. In many remote sensing applications, polygons are instead used to describe regions of interest (e.g., countries and cities) that form the spatial basis for analysis. The values associated with these polygons are estimated by aggregating the underlying gridded raster data within the boundary of the polygon.

Development and Evaluation of a Health-Based Heat Wave Categorization System: A Case Study of Seville, Spain

In the summer of 2022, a team of climatologists and researchers piloted the first heat warning system that ranks heat events based upon human health outcomes. This system uses local all-cause mortality data in addition to meteorological factors including air mass identification and the Excess Heat Factor to identify heat events that are likely to endanger human health in the region and applies three categories representing increasing severity.

The Case for Data-Centered Convening: A New Pathway for Interstate Water Governance

Interstate water management is a highly contested domain in American environmental governance. Competing claims over shared rivers, aquifers, and watersheds have produced decades of litigation, failed compacts, and entrenched political standoffs. Despite widespread recognition that these disputes must be resolved, the institutional mechanisms for doing so have largely stalled.
