Function-based allocation for recycling and waste-to-energy systems: A unit-process framework for attributional LCA

This study proposes a reproducible, function-based allocation framework for attributional life cycle assessment that physically separates recycling systems into waste treatment, material provision, and energy provision to generate consistent, comparable cradle-to-gate footprints for recyclates while explicitly quantifying system inefficiencies and avoiding double counting.

Whole-life carbon emissions and material demand in the Swedish building stock: an archetype-based stock dynamics assessment

This study presents a novel archetype-based modelling framework to assess Sweden's building stock material demand and whole-life carbon emissions through 2045, revealing that while A-phase improvements can reduce emissions by 90%, achieving full carbon neutrality requires further decarbonization of operational energy and material production systems.

Evaluating the hydrocarbon production potential of Shemshak's formation Shale in Shahrud's Dehmolla area, using Rock-Eval Device

This study evaluates the hydrocarbon potential of Jurassic Shemshak Formation shales in Shahrud's Dehmolla area using Rock-Eval pyrolysis, revealing variable organic richness with Type III and IV kerogen and thermal maturity ranging from mature to super-mature, indicating a primary potential for gas generation with some capacity for fluid hydrocarbons.

Life-Cycle Greenhouse Gas Implications of Biomass-Based CFB Boiler Retrofit for Coal Power Decarbonization in Indonesia

This study demonstrates that retrofitting Indonesia's Paiton coal-fired power plant with a biomass-fueled circulating fluidized bed boiler can significantly reduce or even reverse life-cycle greenhouse gas emissions, particularly when utilizing Calliandra wood on degraded land, though the net climate benefits are highly sensitive to land-use changes and biomass supply chain characteristics.

Energy flows through tropical bird and mammal communities reflect anthropogenic effects and biogeographic history

This study reveals that despite similar productivity, bird and mammal communities in the Peruvian Amazon and Borneo channel energy through distinct pathways shaped by biogeographic history and anthropogenic effects, demonstrating that ecosystem functionality cannot be fully understood through species richness alone.

Regional Marine Cloud Brightening Unintentionally Exacerbates Tropical Cyclone Exposure

While regional Marine Cloud Brightening in the eastern Pacific could effectively limit global warming to 2°C, large-ensemble simulations reveal that it unintentionally alters tropical cyclone tracks to significantly increase land exposure and human risk by the end of the century.

Spatiotemporal Dynamics and Health Risk Assessment of Gross Beta Radioactivity in a Tropical Reservoir: Insights from Phase Partitioning and Long-Term Monitoring

This 14-quarter study of the Mudan Reservoir in Taiwan reveals that while summer monsoons significantly elevate dissolved gross beta radioactivity through runoff, the resulting water remains radiologically safe for public consumption, with estimated annual doses far below WHO safety limits despite limited removal by conventional treatment processes.

Embodied Carbon Benchmarking for Low-Carbon Smart Buildings in Saudi Arabia Waqar Hussnain

This study addresses the lack of localized benchmarks for Saudi Arabia's construction sector by developing a practitioner-informed, four-tier embodied carbon benchmark typology for commercial and mixed-use giga project buildings, utilizing cradle-to-completion lifecycle data to guide decarbonization efforts within the Kingdom's Vision 2030 framework.

Geometry and Structural Controls on the Magmatic Emplacement and Geo-spatial Distribution of the San Feliciano Plutonic System, Northern Zacatecas, Mexico: Insights from Integrated Aeromagnetic Modelling and Geological Constraints

By integrating aeromagnetic modeling with geological constraints, this study reconstructs the three-dimensional geometry and structural controls of the Late Cretaceous San Feliciano Plutonic System in Northern Zacatecas, revealing a large, irregularly shaped intrusive body emplaced along a NE–SW trend and subsequently deformed by NW–SE tectonic forces associated with the Mexican Orogen.

LLM Agent-informed 1.5 °C Global Mitigation Pathways Considering Sustainable Development Goals

By coupling the Global Change Analysis Model with an LLM agent-coordinated workflow, this study demonstrates that the temporal pacing of mitigation under a fixed 1.5°C carbon budget critically determines Sustainable Development Goal outcomes, revealing that front-loaded strategies reduce long-term overshoot and pollution but increase near-term pressures, whereas delayed mitigation shifts burdens to the late century and increases reliance on carbon removal.
