Although there is currently much scholarly and policy attention around the concept of just transitions, research on the more specific aspect of distributional justice has received more limited consideration, and it lacks a clear foundation and understanding of the type of inequalities that it is relevant to look at. The main idea motivating this Special Issue is that the study of distributional justice should be guided by a thorough understanding of what well-being is. Moving beyond traditional economic measures, we argue that different notions and conceptual views on individual and social well-being (specifically preference satisfaction, subjective mental states, and human capabilities) may lead to radically different implications in terms of distributional justice and fairness, and how green transitions may affect these. The paper outlines these theories of well-being, and it proposes a novel pluralistic framework that evaluates policies against a vector of well-being criteria. We discuss implications in terms of distributional justice, political feasibility, and policies for directionality, and synthesize the contributions of the articles included in the Special Issue. We conclude that a legitimate just transition requires shifting from <em>ex-post</em> financial compensation to <em>ex-ante</em> procedural justice, thereby empowering groups and individuals to shape the direction of socio-technical change. Future research must focus on operationalizing multidimensional well-being metrics, evaluating spatial and intergenerational trade-offs.</div></div>","PeriodicalId":54294,"journal":{"name":"Environmental Innovation and Societal Transitions","volume":"61 ","pages":"Article 101164"},"PeriodicalIF":6.1,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148958708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fuzzy-set qualitative comparative analysis (fsQCA) is used to identify effective policy instrument mixes and conceptualize them as distinct governance configurations for promoting NEV transition. Results show that successfully governing this transition depends on the strategic recombination of various policy instruments over time. We identify five such effective governance configurations (i.e., specific mixes of policy instruments): “financial-driven” and “market-driven” configurations are highly effective in the emergence phase; network-based and expectation management instruments are core enablers during the growth phase; “comprehensive-driven” configuration integrates multiple policy instruments to promote long-term market sustainability in the consolidation phase. A dynamic trajectory analysis further reveals distinct evolutionary patterns for each of the six policy instruments. The findings provide a novel, configurational perspective on transition governance and contribute to socio-technical transitions literature by enriching understanding of the dynamic interactions of policy instrument mixes in driving transitions.

Drawing on the multi-level perspective (MLP) and patent-based network analysis, it compares Germany and Japan, two leading automotive producers facing similar global decarbonization pressures but pursuing markedly different transition strategies. Using patent co-classification networks (2012-2023), the study maps the structure and evolution of technological niches and their integration into incumbent socio-technical regimes. The findings reveal two contrasting transition pathways. Germany follows a policy-driven, EU-aligned, substitution-oriented trajectory centered on battery electric vehicles. This pathway is characterized by modular innovation structures and rapid regime destabilization, but is accompanied by heightened risks related to labor adjustment and supply-chain dependence. Japan, by contrast, pursues an industry-led, reconfiguration pathway based on technological diversification across hybrid, battery electric, and fuel-cell vehicles, supported by dense innovation networks and strong state-industry coordination. This pathway prioritizes gradual regime adaptation and transition resilience over rapid substitution. By linking patent network structures to transition pathway dynamics, the paper advances sustainability transitions research in two ways. First, it demonstrates how institutional embeddedness conditions the balance between transition speed and resilience. Second, it shows that technological diversification can function as a stabilizing mechanism in regime transformation rather than a factor of transition delay. The findings underscore the need for context-sensitive transition governance and caution against one-size-fits-all decarbonization strategies in mobility transitions.</div></div>","PeriodicalId":54294,"journal":{"name":"Environmental Innovation and Societal Transitions","volume":"61 ","pages":"Article 101177"},"PeriodicalIF":6.1,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148641262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent scholarship has begun to recognise this, developing systemic perspectives on participation. While these richly describe <em>what</em> these interactions look like in practice, we require additional conceptual tools for explaining <em>how</em> their adaptive dynamics unfold. This paper addresses this gap by conceptualising a collection of participatory processes as a Complex Adaptive System (CAS). We develop a framework that empirically applies CAS concepts – nestedness, coupled fitness landscapes, path dependence and emergence – to a collection of participatory processes in the Netherlands. Our results from 21 interviews show how participatory processes are nested within multiple spatial, temporal, institutional and social scales and domains, both within and beyond the energy sector. Furthermore, participatory processes continuously learn from and respond to each other. We observed an interaction with two main emergent patterns in the system as a whole: the development of a milieu of learning on participation and the institutionalisation of participation. Finally, we observed processes of self-reinforcing behaviour and path dependence. Our CAS perspective provides conceptual and methodological tools to better understand the complexity, interdependencies, and change implications of participatory governance in sustainability transitions. Our findings underline the need for (normative) reflexivity in designing and evaluating participatory processes as dynamic components of larger, evolving systems.</div></div>","PeriodicalId":54294,"journal":{"name":"Environmental Innovation and Societal Transitions","volume":"61 ","pages":"Article 101175"},"PeriodicalIF":6.1,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148641263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on 25 semi-structured interviews within the Zeeland industrial cluster in the Netherlands, our analysis reveals a central tension between defensive and adaptive action. Defensive action, predominantly deployed by incumbents, relies on discursive delegitimation—e.g., framing policy goals as unattainable due to infrastructural delays—and substantive investments to secure path-extending trajectories (blue hydrogen). Conversely, adaptive action, primarily driven by new entrants and proactive local governments, combines discursive counter-framing of incumbent narratives with substantive institutional entrepreneurship—such as bottom-up rule creation and local de-locking—to accelerate radical path creation of green hydrogen. We contribute to transition literature by demonstrating how actors navigate persistent institutional uncertainty shaped by co-evolving mechanisms of trust and distrust, thereby driving pragmatic responses like hybrid strategies and coopetition.</div></div>","PeriodicalId":54294,"journal":{"name":"Environmental Innovation and Societal Transitions","volume":"61 ","pages":"Article 101185"},"PeriodicalIF":6.1,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drawing on survey data from the Norwegian Citizen Panel (N = 9997), we find that dislike of specific political parties is a significant, and often stronger, predictor of climate policy support or opposition than party identification or sociodemographic factors. Party dislike has the greatest effect on responses to salient and contested issues, such as wind power expansion. These reactions are particularly pronounced toward smaller challenger and populist parties associated with specific positions on climate-related matters. These dynamics show strong associations between affective responses to political parties and policy attitudes and point at a fragmentation in public opinion, not necessarily over the need for climate action, but over the political associations of specific climate measures. We highlight that understanding these affective and identity-related dynamics of public opinion is essential for assessing the political feasibility of ambitious climate policies and for advancing sustainability transition research, especially in light of the increasingly contentious character of climate policy.</div></div>","PeriodicalId":54294,"journal":{"name":"Environmental Innovation and Societal Transitions","volume":"61 ","pages":"Article 101180"},"PeriodicalIF":6.1,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148843505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated how the coal regime structure was stabilized through interactions among the electricity policy, labor market, and affected region sub-regimes. To explore coal regime structure and its potential toward destabilization under the coal phase-out policy and just transition in South Korea, we conducted in-depth interviews with 18 representatives, systematically recruited from the coal power industry and its policy sector. Data analysis revealed the following findings. First, the electricity policy sub-regime is characterized by centralized state decision-making and limited proactiveness among public power generation companies. Second, the labor market sub-regime demonstrates uneven employment impacts within a multi-layered structure spanning public power generation companies and subcontractors. Third, the affected region sub-regime plays a limited role in the transition process owing to constrained legal and fiscal autonomy. Our analysis shows that interactions among these sub-regimes mutually reinforce regime lock-in, explaining the slow pace of coal phase-out and persistent tensions for a just transition in South Korea. This framework explains why just transition is difficult to reach when each sub-regime is addressed separately, and their interactions are beyond the scope of analysis, leading to missing the intervention entry for destabilization. By linking regime destabilization theory with just transition imperatives, the sub-regime interaction framework provides a transferable analytical framework for equitable coal phase-out pathways beyond South Korea.</div></div>","PeriodicalId":54294,"journal":{"name":"Environmental Innovation and Societal Transitions","volume":"61 ","pages":"Article 101183"},"PeriodicalIF":6.1,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
