Ratio Working Paper No. 309: Förutsättningar för storskaligt infångande av koldioxid.

Download PDF

Abstract

Syftet med denna översiktsrapport är att ge en nulägesbild av möjligheterna till storskalig reducering av koldioxidutsläpp och atmosfäriska koldioxidkoncentrationer genom olika former av NET (Negative Emission Technologies). Enligt 2014 års basscenario från IPCC för maximalt 2°C uppvärming måste de globala koldioxidutsläppen börja minska kraftigt i närtid samt att olika former av NET tas i bruk senast under åren 2030–2045. NETs kritiska roll för måluppfyllnad kan ses i IPCCs scenariodatabas. Utav de 113 scenarier associerade med utfall under 2°C förutsätter 107 av dessa en framgångsrik implementering och storskaligt upptagande av koldioxid både ur själva atmosfären och direkt från olika typer av utsläppskällor. Vår övergripande slutsats är att utifrån nuläget på den tekniska utvecklingen kommer 2 graders målet svårligen uppnås. För att nå måluppfyllnad behövs en kontinuerlig minskning av absoluta utsläpp, att en marknad skapas för koldioxid och en betydligt snabbare utvecklingstakt vad gäller NET, exempelvis genom ökat statligt R&D.

Abstract

The metals sector faces multiple and interconnected barriers to achieving circularity. This study examines steel, aluminum, and copper to illustrate how challenges vary between metals. While copper can often be recycled without quality loss, steel and aluminum face alloy-related limitations that drive downcycling and quality degradation. Using a matrix-based analytical framework, the study maps the interactions between economic, technological, institutional, and social constraints, distinguishing between primary drivers, secondary effects, feedback loops, and lock-in mechanisms. The results show strong reinforcing links between economic, technological, and institutional domains, with social factors playing a more indirect role. These findings align with observed industry patterns while adding a structured, quantitative perspective. By clarifying how different barriers combine and reinforce one another, the analysis identifies priority areas for intervention to advance metals recycling and support the transition toward a more circular economy.

Abstract

Circular economy debates often acknowledge material lifespans and delays, but time is usually treated as a contextual issue rather than a structural barrier. The contribution is to reframe circular economy transitions as intertemporal processes by treating time as an endogenous structural barrier. A framework is developed that classifies goods into short-, medium-, and long-lived categories, demonstrating how lagged inflows and valuation biases suppress aggregate circularity even when technology improves. By making temporal mechanisms explicit, the analysis explains why indicators remain stagnant despite policy and efficiency gains. The contribution is to introduce time as an endogenous barrier, integrating insights from environmental and resource economics into circular economy theory and showing how delayed substitution shapes both firm investment and policy outcomes.

Abstract

Artificial intelligence is reshaping academia, but instead of liberating scholars, AI might keep them running faster just to stay in place. This paper theoretically explores how AI increases institutional expectations rather than reducing workload. Using a formal workload model, the study examines how automation affects academic tasks, revealing that while AI streamlines some processes, it also creates new responsibilities in research, publishing, and administration. A case study illustrates how scholars experience rising pressures to verify AI-generated work, adapt to changing publication norms, and meet intensifying institutional demands. The findings suggest that AI’s role in academia is not one only of simplification, but acceleration—a race where efficiency gains are quickly absorbed, where the pursuit of academic excellence becomes ever more demanding, and where scholars must continuously push forward, not to advance, but merely to avoid falling behind.
