Integrated Assessment Models (IAMs) have become the dominant approach for envisioning different mitigation scenarios. While they are not intended to deal with justice, IAM assumptions and structure justice implications that been explicitly discussed or clearly elucidated in critical accounts of modelling practices. Given their key influence policy decisions increasing imperative just transitions climate action, a more explicit consideration dimensions IAM-derived pathways is necessary. This paper reviews existing critiques IAMs through three-dimensional lens examine extent which concerns emerge remain unnoticed literature. review helps substantiate how disciplinary geographical norms shape choices. Focusing mostly on role technoeconomic framings processes model-based knowledge production, drawing from theorists, such as Nancy Fraser, article shows approaches overlooked questions recognition subsuming distributional participational concerns. It also points need engage other systems cognitive transformative critique relevant knowledge, well strive diverse, equitable inclusive options.

Abstract The deployment of carbon dioxide removal is essential to reach global and national net-zero emissions targets, but little attention has been paid its practical by countries. Here, we analyse how methods are integrated into 41 the 50 Long-term Low Emission Development Strategies submitted United Nations Framework Convention on Climate Change (UNFCCC), before 2022. We show that enhancing forest soil sinks most advocated strategies only explicitly quantified in 12. Residual 2050 20 them use forests achieve targets. quantify both residual identify constraints, such as wildfire risks limited geological CO 2 storage capacity. These also highlight need for international cooperation. Taken together, suggest UNFCCC should urgently strengthen reporting requirements long-term climate strategies.

After the Industrial Revolution, ever-increasing atmospheric CO2 concentration has resulted in significant problems for human beings. Nearly all countries world are actively taking measures to fight carbon neutrality. In recent years, negative emission technologies have attracted much attention due their ability reduce or recycle excess atmosphere. This review summarizes state-of-the-art technologies, from artificial enhancement of natural sink technology physical, chemical, biological methods capture, as well utilization and conversion. Finally, we expound on challenges outlook improving accelerate pace achieving

Abstract The feasibility of different options to reduce the risks climate change has engaged scholars for decades. Yet there is no agreement on how define and assess feasibility. We feasible as “do‐able under realistic assumptions.” A sound assessment based causal reasoning; enables comparison across options, contexts, implementation levels; reflexively considers agency its audience. Global scenarios are a good starting point assessing since they represent pathways, quantify levels, consider policy choices. Yet, scenario developers face difficulties all relevant causalities, realism assumptions, assign likelihood potential outcomes, evaluate their users, which calls external assessments. Existing approaches mirror “inside” “outside” view coined by Kahneman co‐authors. inside unique challenge seeks identify barriers that should be overcome political choice, commitment, skill. outside assesses through examining historical analogies (reference cases) given option. Recent studies seek bridge views “feasibility spaces,” identifying reference cases option, measuring outcomes characteristics, mapping them together with expected characteristics Feasibility spaces promising method prioritize realistically achievability goals, construct empirically‐grounded assumptions.
