This study explores spatial disparities in public perceptions of decarbonization and acceptance of the bioeconomy in a transitioning region. A structured survey of 465 residents across Western Macedonia assessed views on environmental, economic, and institutional aspects using Likert-scale items. Statistical analyses, including K-means clustering, revealed significant variation in perceptions, with institutional support, visible investment, enterprise activity, and public sentiment emerging as key predictors of acceptance. Institutional engagement showed the strongest influence. Findings underscore the uneven experience of transition across sub-regions and highlight the need for inclusive, place-sensitive policies to foster trust, enhance communication, and ensure a truly just transition process.

Air pollution from lignite combustion represents a major environmental and public health concern, particularly for cardiovascular disease. This study investigated the relationship between ambient air pollution and hospital admissions for Acute Coronary Syndromes (ACS) and Atrial Fibrillation (AF) in Western Macedonia, Greece—a region historically dominated by lignite mining and power generation. Air quality data for PM₁₀, SO₂, and NO_x from 2011–2014 and 2021 were analyzed alongside hospital admission records from four regional hospitals (Kozani, Ptolemaida, Florina, Grevena). Spatial analyses revealed significantly higher pollutant concentrations and cardiovascular admissions in high-exposure areas near power plants compared with the control area. Temporal analyses demonstrated a pronounced decline in pollutant levels between 2014 and 2021, coinciding with lignite phase-out and accompanied by a marked reduction in ACS and AF hospitalizations, particularly in the high-exposure areas of Ptolemaida and Florina. Correlation analyses indicated modest but significant positive associations between monthly pollutant concentrations and cardiovascular admissions. These findings provide real-world evidence that reductions in air pollution following lignite decommissioning were associated with improved cardiovascular outcomes. The study underscores the medical importance of air quality improvement and highlights emission reduction as a critical strategy for cardiovascular disease prevention in transitioning energy regions.

Air pollution constitutes a major environmental determinant of cardiovascular morbidity and mortality worldwide. Western Macedonia, Greece, has historically hosted the largest lignite mining and combustion complex in Southeastern Europe, creating a unique exposure environment. This study investigates the relationship between air pollutant concentrations and cardiovascular hospital admissions over a ten-year period in this lignite-dependent region. Daily concentrations of particulate matter (PM₁₀), sulfur dioxide (SO₂), nitric oxide (NO), nitrogen dioxide (NO₂), and total nitrogen oxides (NO_x) were collected from regional monitoring stations for the winters of 2011–2021, while corresponding daily cardiovascular hospital admissions were obtained from the regional hospitals of Kozani, Ptolemaida, Florina, and Grevena. Spearman’s rank correlations and Friedman’s non-parametric tests were applied to assess temporal and spatial associations between pollutant levels and hospital admissions. A marked decline in air pollutant concentrations, particularly PM₁₀ and SO₂, was observed across the decade, coinciding with a significant reduction in cardiovascular hospitalizations. Specifically, PM₁₀ levels fell from ~75 μg/m³ to ~30 μg/m³ in Florina and from ~53 μg/m³ to ~11 μg/m³ in Ptolemaida, while SO₂ concentrations decreased by more than 90% across all sites. Cardiovascular admissions declined by 20–40% depending on the region over the same period. Significant but modest positive correlations were detected between PM₁₀ and admissions in Florina (ρ = 0.138, p = 0.017), SO₂ in Ptolemaida (ρ = 0.122, p = 0.034), and NO₂ in Kozani (ρ = 0.115, p = 0.045). Regions located near lignite combustion sites consistently exhibited higher pollutant levels and hospitalization rates. The study provides quantitative evidence linking air pollution from lignite combustion to adverse cardiovascular outcomes. The parallel decline in both pollution levels and hospital admissions underscores the cardiovascular benefits of emission reduction and the ongoing energy transition in Western Macedonia. Continuous air quality monitoring and preventive public health measures remain essential for safeguarding cardiovascular health in former coal-based regions.

Accurate forecasting of carbon credit prices is increasingly vital for the effective functioning of forest carbon markets, which play a growing role in global climate mitigation strategies. Against this backdrop, the present study conducts a systematic literature review to evaluate the state of carbon price forecasting methodologies, with particular emphasis on their applicability to forest-based carbon credits. The review highlights the predominance of machine learning (ML) and hybrid modeling approaches, which demonstrate enhanced predictive capabilities relative to conventional econometric techniques, particularly in capturing nonlinear dynamics and integrating heterogeneous data sources. However, their predictive power is limited by data scarcity, market opacity, and regulatory volatility. These issues are particularly severe in voluntary forest credit markets. The review identifies a critical research gap. Few studies explicitly model the behavior of forest credit prices. The findings suggest that future research should prioritize the development of policy-sensitive, scenario-based models that incorporate ecological, economic, and regulatory dimensions. While the majority of studies concentrate on compliance carbon markets, the methodological insights and forecasting approaches reviewed are highly relevant for the evolving forest carbon sector, nature-based mitigation strategies, and climate solutions. It also offers guidance for creating more transparent and robust forecasting tools in the forest carbon sector.

Greece faces increasing exposure to natural hazards—particularly wildfires, floods, and earthquakes—driven by climatic, environmental, and spatial factors. This study systematically reviews 108 peer-reviewed publications and official reports, applying PRISMA methodology to evaluate the effectiveness of the national civil protection system. The analysis reveals localized progress, notably in earthquake preparedness due to strict building codes and centralized oversight, but also persistent systemic weaknesses. These include fragmented governance, coordination gaps across agencies, insufficient integration of spatial planning, limited local preparedness, and reactive approaches to disaster management. Case studies of major events, such as the 2018 Mati wildfires and 2023 Thessaly floods, underscore how communication breakdowns and delayed evacuations contribute to substantial human and economic losses. Promising developments—such as SMS-based early warning systems, joint training exercises, and pilot GIS risk-mapping tools—illustrate potential pathways for improvement, though their application remains uneven. Future priorities include strengthening unified command structures, enhancing prevention-oriented planning, investing in interoperable communication systems, and fostering community engagement. The findings position Greece’s civil protection as structurally capable of progress but in need of sustained, systemic reforms to build a resilient, prevention-focused framework for increasing disaster risks.

This study examines the regional disparities in public perceptions of decarbonization and the acceptance of the bioeconomy within Western Macedonia, a Greek region undergoing structural economic change. While the environmental benefits of decarbonization, such as reduced carbon emissions and improved air quality, are widely acknowledged, perceptions of economic and social outcomes, including investments, new business development, and policy support, vary significantly across sub-regions. To this end, a structured survey was conducted among 765 residents, utilizing Likert-scale items to assess attitudes, with demographic data providing a contextual framework. Statistical analyses, incorporating techniques such as one-way analysis of variance (ANOVA), Kruskal–Wallis, and multiple regression, were employed to explore spatial variations and identify the primary drivers of bioeconomy acceptance. The results indicate that perceived government action, visible investment, new enterprises, and a positive view of public sentiment are all significant predictors of acceptance, with institutional support showing the strongest influence. The findings reveal that certain areas feel less engaged in the transition, expressing skepticism about its benefits, while others report more optimism. This disparity in perception underscores the necessity for targeted policy interventions to ensure inclusive and equitable participation. The study emphasizes the necessity for regionally responsive governance, enhanced communication strategies, and tangible local development initiatives to cultivate public trust and support. The study makes a significant contribution to the broader discourse on just transitions by emphasizing the role of place-based perceptions in shaping sustainable change.

This study aims to demonstrate the effectiveness of the Delphi SWOT tool in formulating a bio-economy strategy for an isolated region. The analysis will highlight the management and planning aspects that are essential for assessing the internal and external circumstances of the region. A total of 16 experts were selected to participate in the Delphi method, which was used to investigate the current state of the bio-economy in the agricultural sector of a small isolated region in Greece. Following the convergence of the experts’ opinions, a SWOT analysis and a set of policy recommendations for the formulation of a bioeconomy strategy were derived. The formulation of a bioeconomy strategy in an isolated region reveals a promising landscape full of opportunities, but also full of challenges. The region has a number of intrinsic advantages that can be used to advance the bioeconomy. The focus on an isolated region limits the applicability of the findings to other regions with different socio-economic contexts. In addition, the Delphi method relies on expert opinion, which is inherently subjective. The bioeconomy concept has the potential to address the challenges faced by a small, mountainous, rural region whose economy has historically been based on energy production from lignite. To facilitate a sustainable transition, it is essential to harness the region’s human capital, promote sustainable agricultural practices, develop innovative products and processes, and establish new value chains that can stimulate economic growth.

This study explores how university students’ engagement in sustainability-themed extracurricular activities influences their awareness of the 17 Sustainable Development Goals (SDGs). Given the critical role of higher education in advancing sustainability, this research assesses initiatives such as environmental action clubs, sustainability research, eco-innovations, green campuses, and training workshops for fostering awareness, engagement, and leadership. A cross-sectional quantitative design targeted 400 university students in Greece involved in sustainability-related extracurricular activities. Structured online questionnaires were used, and multiple regression analysis examined the relationship between extracurricular activities and SDG engagement. The findings highlighted that all five activity types significantly enhance students’ sustainability awareness. Environmental action clubs improve knowledge of climate change and waste reduction, while research projects strengthen engagement with renewable energy and climate resilience. Eco-innovation challenges foster problem solving and interdisciplinary collaboration, particularly in urban and industrial sustainability. Green campus initiatives promote practical sustainable strategies, and capacity-building programs develop leadership and teamwork skills. Extracurricular activities serve as transformative tools that bridge theoretical knowledge with real-world sustainability applications, equipping students with the mindset and skills to address global challenges. Universities and policymakers should enhance funding, digital integration, and collaborations to expand the reach of these programs. Future research should assess the long-term impact of student participation on sustainable behavior and broader societal well-being.

The development of the bioeconomy in the European Union is promoted through various policies. In Greece, however, there is a paucity of research on bioeconomy issues and policies at both the national and regional levels. This study systematically examines the feasibility of developing a bioeconomy blueprint within the context of a geographically isolated and mountainous region. By employing an integrated strategic framework combining sustainable resource management, innovation and participatory governance, the proposed framework emphasizes the transition from conventional, unsustainable economic practices to a contemporary development paradigm underpinned by the tenets of the circular economy and the utilization of local resources. A central tenet of the proposed framework is the enhancement of collaborative endeavors among local stakeholders, academic institutions, and business entities, with the overarching objective being the promotion of cutting-edge technologies and the economic diversification of the region. Concurrently, emphasis is placed on the necessity to establish conducive policies, regulatory frameworks, and financial mechanisms that will facilitate the development of sustainable industries and mitigate the environmental impact. The text emphasizes the importance of human resources development through educational and training programs, ensuring adaptability to the demands of the emerging bioeconomy. The study concludes that, despite the inherent difficulties arising from geographical isolation and limited access to resources, the region has the potential for sustainable development. The region’s capacity for sustainable development is contingent upon the implementation of suitable strategies and the mobilization of investment, which will be instrumental in the establishment of a robust and environmentally sustainable economic model.

The concept of the bioeconomy holds great promise for promoting green growth and competitiveness across Europe through the use of renewable biological resources, such as plant and animal biomass, while adhering to the principles of circularity. Despite its introduction by the European Commission in 2015, little effort has been made to define or describe what exactly a circular bioeconomy entails. In the case of Greece in particular, however, the survival of the region of Western Macedonia appears to be highly dependent on sustaining its agricultural activity by incorporating elements related to this crucial sector of the economy. In order for this agricultural transformation to be effective, bio-economic practices relevant to crop production and appropriate alternative management practices must be universally implemented at all levels. To achieve this, it was necessary to collect questionnaires from 412 farmers in the region for analysis purposes, and to classify their responses based on k-means cluster analysis, which later formed these systematic groups: modernists, early adopters and latecomers. Evaluation of these categories revealed a variety of factors, such as age and income, that significantly influenced their attitudes towards adopting bioeconomy farming practices and related circularity principles. Overall, understanding these challenges opens the door for policy decisions aimed at supporting the development of sustainable rural areas.
