The urgency of addressing climate change has underscored the need for precise carbon management—an approach that precisely monitors, assesses, and manages carbon emissions and sequestration at fine spatial, temporal, and sectoral scales. This perspective paper examines the current state of precise carbon management, highlighting advancements in ground-based observations, remote sensing, process-ba
“Right to repair” (R2R) has become an important policy objective in European Union (EU) policy and law. The main objective of R2R is to remove barriers that inhibit consumers from repairing the products they own. The EU has made use of different regulatory frameworks to enforce R2R, most notably product regulation to induce design changes and ensure that spare parts and software updates are availa
Does the level of attention that politicians direct toward complex environmental problems impact how frontline bureaucrats in municipal settings form relationships? The collaborative interactions among civil servants are a defining feature of environmental governance, drastically shaping how issues are addressed. In this article, the authors incorporate political attention, or the priority status
Tropical rainforests have complex responses to seasonal climatic variations. Compared to the Amazon and Asian rainforests, the Congo rainforest exhibits a more widespread bimodal seasonal pattern, yet it remains understudied. Here, we use three independent satellite-based vegetation indices to investigate the seasonal variations of the Congo rainforest, including solar-induced chlorophyll fluoresc
In this paper, we investigate how the lockdown-induced exposure to remote work affected the likelihood of switching to longer commutes using a longitudinal full-population register of Swedish employees. We find that employees with little experience of longer commutes were more likely to start commuting longer if they had occupations with high potential for remote work. Examining heterogeneity acro
Combustion of NH3 with H2 addition can improve the combustion stability. In this study, the laminar burning velocities (LBVs) of NH3/H2/O2/CO2 mixtures were determined under atmospheric pressure and an initial temperature of 303 K by the heat flux method, spanning CO2 fractions of 0.50-0.75, H2 fractions of 0.20-0.70, and equivalence ratios of 0.6-1.5. Evaluations of three kinetic models (modified
Investeringssparkonto (ISK) infördes den 1 januari 2012 som en schablonbeskattad sparform för fysiska personer. I stället för att beskattas för faktiska utdelningar och kapitalvinster erlägger innehavaren en årlig skatt beroende på ett kapitalunderlag som approximativt motsvarar portföljens förväntade avkastning. Systemet är kon-struerat med utgångspunkt i en inhemsk skattemässig kontext. När inneThe Swedish Investment Savings Account (ISK) is a lump-sum taxed savings vehicle introduced on 1 January 2012. Instead of being taxed on actual dividends and capital gains, the account holder pays an annual tax calculated on a deemed capital base approximating the portfolio’s expected return. When foreign listed shares are held in an ISK, a complication arises: the source state’s right to withhold
Datacenter utgör en central del av den digitala infrastrukturen, och efterfrågan på datacenterkapacitet ökar snabbt i takt med digitalisering, AI-utveckling och framväxten av det smarta samhället. Samtidigt står datacenterbranschen inför betydande utmaningar kopplade till ett energisystem under omställning samt en tilltagande geopolitisk osäkerhet som aktualiserat frågor om digital suveränitet och
Simuleringar för avancerad återvinning av blandat plastavfall Det globala plastavfallet ökar men återvinningsgraden följer inte med. Kemisk plaståtervinning är en lovande metod men står inför ingenjörsutmaningar kopplade till värmeöverföring och energiförbrukning. Denna studie använde beräkningsmodellen CFD-DEM för att undersöka uppvärmningen av blandat plastavfall i en kemisk återvinningsprocesGlobal plastic waste production has more than doubled in the past two decades, with plastic packaging accounting for 40% in 2019. Due to low recycling rates, pollution and limited fossil resources, increasing circularity in the plastic industry has become increasingly important. Chemical recycling through pyrolysis, unlike mechanical recycling, can treat contaminated, mixed plastic waste and incre
This thesis investigates the economic and operational consequences of price-responsive operation of a large-scale alkaline electrolyzer producing hydrogen for fossil-free steel production. A time-resolved linear optimization model was implemented in Python, describing the interaction between a 740 MW electrolyzer (37 units of 20 MW), a hydrogen storage and a constant hydrogen demand. Three operati
This thesis aims to address a dual crisis. Globally, the construction industry relies on a linear “take-make-dispose” approach and a “tabula rasa” tactic in each novel project, draining the Earth’s resources. Locally, around a half of residential buildings in Riga, Latvia, are of Soviet mass housing typology. These structures are on the verge of structural expiration, at risk of progressive collap
This thesis investigates the performance and hysteresis behaviour of building-integrated halide perovskite solar modules (BIPV PSCs) under various environmental conditions. With perovskite solar cells emerging as promising third-generation photovoltaic technology due to their high efficiency, scalability, and relatively low production costs, their integration into building surfaces offers signific
Precision medicine for complex diseases uses individual-level characteristics to improve prediction of risk, therapeutic response and prognosis. Many precision medicine studies leverage existing data types and analytic methods to reveal new insights; however, beyond oncology, there has been limited success in translating precision medicine research for complex diseases into clinical practice. Thus
Background: Climate change is emerging as a major global health crisis, escalating occupational hazards across all sectors and exacerbating social inequalities. Workers, especially those in outdoor, informal, and precarious employment are increasingly exposed to multiple hazards, leading to adverse physical and mental health outcomes, productivity losses, and premature death. Objective: This comme
Our societies are ageing, and an urban-regional perspective on these developments is urgently needed. This figure shows an uneven geography of population ageing in Sweden—in the level and pace of ageing—and calls for variegated societal adaptations across municipalities.
It has been suggested that an intensified trade war between China and the US could reduce CO2 emissions associated with exports. We develop an export-greenfield-endogenous merger model, showing that significantly increased tariffs can enable domestic firms to undertake entry-deterring acquisitions. This forces foreign firms to remain exporters, which, in turn, leads to higher emissions. Strong com
