- Decarbonization Transition Pathways and Regional Trends: Insights from One Million StudiesPublication . Bento, Nuno; Alves, Tiago; Ribeiro, Ricardo; Fontes, MargaridaABSTRACT: As global temperatures near critical thresholds and emissions continue to rise, the urgency for strategic, accelerated decarbonization grows. Despite a vast climate mitigation literature, a systematic understanding of actionable pathways remains limited. Here, we apply artificial intelligence to analyze over one million scientific papers (2011–2021), generating a data-driven typology of six archetypal decarbonization pathways: Technology Breakthrough, Electrification of Uses, Integrated Policy, Decarbonization of Electricity, Demand Reduction & Co-benefits, and Land Use & Circularity. Regional patterns show Electrification of Uses prevailing in Europe (EU27), while Technology Breakthrough dominates in China, the US, and Japan. Increasing political and societal resistance to mitigation makes the strategic selection and combination of pathways even more critical. Our analysis highlights key synergies between pathways, the scientific competencies required to support them, and persistent gaps—particularly in Land Use and Circularity. We also compare current climate policy directions with the typology, revealing alignment gaps that may weaken policy effectiveness. This framework enables policymakers to better match strategies with regional capacities and research strengths, offering a more coherent approach to decarbonization. Strengthening the integration of science, technology, and policy is essential to overcome fragmentation and deliver the emissions reductions needed to meet the net-zero climate targets.
- Strategic pathways for decarbonization: a data-driven typology to strengthen climate policyPublication . Bento, Nuno; Alves, Tiago; Ribeiro, Ricardo; Fontes, MargaridaABSTRACT: As global temperatures approach critical thresholds and emissions continue to rise, the urgency for strategic, accelerated decarbonization grows. The climate mitigation literature is vast, but evidence on how mitigation options cluster into overarching decarbonization pathways remains fragmented. Here, we use artificial intelligence–enabled text and citation analysis on an initial corpus of over one million scientific papers (2011–2021) to derive a data-driven typology of six recurrent decarbonization pathways: Technology Breakthrough, Electrification of Uses, Integrated Policy, Decarbonization of Electricity, Demand Reduction & Co-Benefits, and Land Use & Circularity. Rather than proposing new mitigation options, this typology organizes existing work into a small set of archetypal strategies and maps their prevalence across regions, disciplines, and policy orientations. For example, Electrification of Uses is most prominent in the EU27, while Technology Breakthrough dominates in China, the United States, and Japan. The analysis highlights synergies and complementarities between pathways, the scientific competencies that typically underpin them, and persistent gaps – particularly in Land Use & Circularity. We illustrate the policy relevance of the typology by comparing pathway profiles with stated climate policy directions, identifying areas where research and policy emphases are misaligned. This framework can support policymakers and researchers by benchmarking policy portfolios against the typology and highlighting research needs associated with national decarbonization goals.
- Typology of pathways for decarbonization [Resumo]Publication . Bento, Nuno; Alves, Tiago; Ribeiro, Ricardo; Fontes, MargaridaABSTRACT: Addressing the urgent climate change requires a clear knowledge of the options available, as well as an understanding of the possible strategies to reduce carbon emissions. Identifying realistic pathways for decarbonization is crucial to inform agents’ decisions about the relevant measures (Turnheim & Nykvist, 2018), with unawareness of these pathways often delaying climate action (Bergek et al, 2023). This paper seeks to identify, categorize, and analyze decarbonization pathways from the scientific literature, uncovering cross-cutting dimensions, interconnections, and regional trends for enhanced decision-making and accelerated change.
