Medium- and heavy-duty vehicles are a major source of greenhouse gas (GHG) emissions in the United States and globally. Batteries and fuel cells can play a critical role in decarbonizing this sector. ...

Rooftop solar photovoltaics are important in generating electricity from renewable sources, yet estimates of its potential vary widely because of inconsistent definitions and measurements. Moreover, a...

Electric vehicle (EV) adoption is projected to raise global battery demand and pose sustainability challenges driven by the demand for critical minerals, energy-intensive and costly production, and en...

We evaluated 28 drill-tested North American (NA) rare earth element (REE) deposits and their suitability for commercialization to supply domestic end-use demand. Tonnages and grades (total rare earth ...

Air-source heat pumps (ASHPs) provide high-efficiency electric space heating and play an important role in residential decarbonization. In cold climates, low outdoor temperatures reduce ASHP efficienc...

Urban informality scholarship is concerned with injustice and antidemocratic practices. It addresses these issues by engaging with and critiquing urban displacement, inequality, and exclusionary gover...

Clean hydrogen is a promising decarbonization pathway, yet it continues to face a chicken-and-egg problem where high costs and sparse infrastructure have not aligned with demand. To better coordinate ...

This article, the ninth in the series, presents kinetic and photochemical data sheets evaluated by the International Union of Pure and Applied Chemistry (IUPAC) Task Group on Atmospheric Chemical...

Climate change is fueling more frequent and severe droughts, with growing consequences for water security, food production, biodiversity, and ecological wellbeing. Yet responses remain too often react...

This essay considers the political potential of informality as a force for challenging authoritarianism and creating more equal and democratic outcomes. Building on Bandauko's concept of ‘subaltern su...

As solar capacity grows in the United States, there are increasing concerns about managing End-of-Life (EoL) photovoltaic (PV) modules. Circularity through reuse and recycling aims to reduce EoL manag...

This capstone project evaluated the technical and economic feasibility of producing hydrogen for return-to-base trucking in Southeast Michigan. Two hydrogen production pathways were studied: green hyd...

Urban agriculture (UA) is frequently promoted as a pathway to improve urban sustainability, food security, and resilience, yet cross-city evidence on its scalable, system-wide impacts remains limited ...

Urbanization drives global socio-spatial transformation. Informality is central to this transformation, but is treated as a peripheral process on the margins of cities and economies. Informality is of...

This article examines the securitization of the Marange diamond industry in Zimbabwe, arguing that it represents a deliberate political strategy to engineer an “architecture of opacity” for regime sur...

Intermittent water supply (IWS), where piped water is not continuously available, can compromise water security and quality. Extreme rainfall may exacerbate these risks by enabling microbial contamina...

Global warming and electric heat pump adoption will, together, likely have a complex effect on energy burdens in the United States. Here, for 10,000 representative buildings in 28 U.S. cities, we esti...

Artisanal and small-scale mining (ASM) is often informal and constitutes the leading nonfarm source of rural income in much of the world. Despite international support, over a billion dollars invested...

Growing evidence suggests that extreme precipitation increases over most regions globally as the climate warms. However, it remains poorly understood how the fraction of annual precipitation from extr...

We comment on the recent article by Vincent at al.

Meeting global decarbonization targets requires large-scale, low-carbon hydrogen (H2) production around midcentury. A crucial pathway for this production is electrolysis driven by renewables, tying hy...

Electric vehicles (EVs) are key to transportation decarbonization, yet their battery performance and longevity are vulnerable to temperature extremes, which will be affected by climate change. Battery...

Urban resource circularity – the symbiotic sharing of material and energy between urban actors - reduces demand for raw resources and waste generation. Researchers currently lack a unified vernacular ...
