Special Issue Information

Dear Colleagues,

In recent decades, the environmental crisis caused by the over-exploitation of resources coupled with the reckless consumption and production models and climate change has increased the urgency to act in order to preserve the survival of the whole ecosystem (García-Sánchez et al., 2021). The recent COVID-19 outbreak has exacerbated this climate and environmental emergency state, imposing new revolutionary challenges to tackle (García-Sánchez et al., 2020). Therefore, policymakers, public and private organizations and citizens have been called on to co-operate to address this global trial.

In this context, Ecological Transition (ET) has emerged as the best way to cope with this crisis. ET is at the heart of the current political debate and many projects of the most important European and world states. The aim is to achieve a changing process to revive the global economy and all the productive sectors within a well-defined framework focused on environmental respect and protection.

In order to achieve this purpose, an economic paradigm shift is required. The traditional linear economic model that relies on the take–make–dispose paradigm—based on the continuous extraction of raw materials, mass consumption and waste disposal at the end of products life stage—has been increasingly considered unsustainable (Ghisellini et al., 2020). This paved the way for adopting a more sustainable economic model. In contrast, Circular Economy (CE) is defined as an economy designed to "regenerate itself": biological materials are reinserted into the biosphere, and technical origin materials are designed to be reused with a minimum loss in quality. Thus, implementing CE principles—based on the practices of reduction, reuse and recycle—in the business strategies should stimulate the organizations in creating environmental value and enhance efficiency in resources and process management.  

Many interventions and regulations at both European and international levels have been enacted to promote CE policies.  The launch in 2015 of the European Circular Economy action plan for 2020 has allowed the implementation of the EU product policy framework for the CE (European Commission, 2014; 2015; 2016a; 2016b). Attuned, the 2030 Agenda for Sustainable Development has included CE principles in the definition of the 17 Sustainable Development Goals (SDGs). Furthermore, a new CE action plan was introduced in 2020 as a part of the European Green Deal (European Commission, 2019a; 2019b; 2019c; 2020).  

The relevance of CE in driving the global society's transition towards sustainable development has also sparked interest among academics. Several scholars have started investigating methods and tools for shaping production and consumption processes (e.g., Ghisellini et al., 2016; Masi et al., 2017).  CE has also been investigated as a tool to shape corporate decision-making processes towards the achievement of sustainability pillars' (e.g., Geissdoerfer et al., 2016; Lewandowski, 2016; Merli et al., 2018). A recent stream of literature has begun to explore how companies communicate their transition toward a circular economy through non-financial reports such as sustainability and integrated reporting, also investigating the determinants (Raimo et al., 2021; Kuo and Chang, 2021).

Literature has shown that in order to catalyze the ET, the shift towards the adoption of CE practices is required at a supply chain level, rather than the individual company level, engaging all the actors of the supply chain (Esposito et al., 2020). Moreover, the adoption of digital technologies for process management has been identified as a strategic enabler for developing CE business models through data-driven input  (Pagoropoulos et al., 2017; Gupta et al., 2019).

Despite the relevance of this topic and the growing attention of the scientific community, the debate about ET and CE is still in its embryonic stage. Therefore, the aim of this Special Issue is to collect high-quality original contributions and review papers focused on CE and ET in different knowledge fields. Authors are also encouraged to propose multidisciplinary approaches for CE business models investigations. 

This Special Issue will welcome scientific papers related but not limited to the following topics:

  • Circular strategies for sustainable consumption;
  • Circular Economy and Ecological Transition at a supply chain level;
  • Circular Economy indicators;
  • Circular Economy disclosure and communication;
  • Circular Economy and urban sustainability;
  • Circular Economy tools (e.g., Life Cycle Assessment; Life Cycle Costing; Material Flow Analysis);
  • Big Data Analytics and data-driven decision-making processes for Circular Economy.

When Do Supply Chains Strengthen Biological and Cultural Diversity? Methods and Indicators for the Socio-Biodiversity Bioeconomy

The bioeconomy has gained traction among the broader discourses on sustainable development, ecological transition, and the circular economy. Governments in the Global North and international institutions maintain that the bioeconomy can gradually replace fossil-based raw materials and nonrenewable resources with biomass and biological renewables. The Global South has increasingly adopted the approach, but with important variations across mega-biodiverse regions. In these regions, the bioeconomy must encourage economic activities that preserve biodiversity and strengthen local communities, promoting their well-being and cultural diversity. This paper argues that conventional research methods and indicators are not fit for this purpose. We therefore propose an alternative method and indicators and present an initial validation of the approach with an application to the pirarucu (Arapaima gigas) value chain in the Brazilian Amazon. By applying a bottom-up approach to evaluation that considers the perspective of the individuals and communities involved, the proposed methodology captures relevant dimensions of the value chain—including trade-offs—while identifying bottlenecks and the role of institutions. It also allows for verification of the achievement of the objectives of the socio-biodiversity bioeconomy in this model. The application to the case study finds that the managed pirarucu fisheries are a viable value chain associated with improved fish stocks and lower than average forest loss. Socio-economic benefits include the generation of reasonable income and greater participation by women. Income remains a complement to other sources of livelihood, however, and attractiveness to local communities is an issue. Positive outcomes are owed largely to local knowledge, collective action, and the role played by meta-organizations, while negative ones such as overfishing have resulted from institutional failures. Conventional analysis would likely not have considered these factors and missed these policy lessons. This corroborates the view that alternative methods and indicators are needed for the socio-biodiversity bioeconomy. While the application to the case study suggests the method and the indicators are conceptually suitable, we identify a number of shortcomings regarding the identification of interventions, attribution, and monitoring of the sustainability of the model.

The circular economy is increasingly establishing itself as a model capable of overcoming the current linear economy of production and consumption recognized as unsustainable by society. Its relevance has also attracted the attention of academics, interested not only in the implementation methods of the circular economy, but also in the ways in which companies communicate information about them. However, although in recent years some scholars have begun to investigate the circular economy disclosure (CED), research on this topic is still in an embryonic state. In fact, in the academic literature there are only a few studies related to the CED and its drivers. This study aims to fill this gap by investigating, under the lens of stakeholder theory, the effect of firm characteristics on the level of CED. To this end, it firstly involves the use of a manual content analysis of the sustainability reports drawn up by 88 international companies to measure the level of CED and, secondly, a regression model to test the impact of the firm characteristics. Empirical results demonstrate a positive effect of firm size, financial leverage and firm profitability on the level of CED. The results have important practical implications for firms and policymakers. Full article

The global climate is showing altered temperatures and precipitation levels. Forests can be a stabilizing force in climate change. They regulate the nutrient cycle, protect species and diversity, and support livelihoods that drive holistic growth. Presently, the forest ecosystem’s capacity to withstand change is being undermined by the rate of change, along with anthropogenic pressures and the specificities of mountainous regions. Here, we attempted to design a ‘forest vulnerability index’ using field measurements and household surveys. A total of 71 quadrants were laid out, and 545 respondents were interviewed in 91 villages along the altitudinal gradient (altitude < 1200 m asl (Zone A), 1200–1800 m asl (Zone B), and >1800 m asl (Zone C)) of the Pauri district of Uttarakhand, India. The village-level data were normalized and combined to represent climate change impacts and the dimension of vulnerability. The IPCC (2014) protocol was used to assess forest vulnerability. The highest vulnerability was recorded in Zone ‘B’, and higher sensitivity, higher climate change impacts, and lower adaptive capacities were recorded in Zone ‘B’ and ‘C’. The approach is comparable within the district and between the states. In enhancing our shared understanding of forest degradation, the results are of value to policy/decision-makers, implementers, and adaptation funding agencies, who can use them to assess the scale, cause, and actions for adaptation.

The objective of this study is to investigate the impact of exports, renewable energy, and industrialization on the ecological footprint (EF) of India over the period spanning from 1970–2017 by employing the newly developed augmented ARDL (A-ARDL) co-integration approach and the novel dynamic ARDL (D-ARDL) technique. The empirical results demonstrate that exports and renewable energy consumption reduce the EF, while industrialization intensifies the EF. More precisely, a 1% increase in export (renewable energy consumption) reduces the EF by 0.05% (0.09%). In addition, the short-run elasticity of the GDP is found to be larger than the long-run elasticity indicating the possibility of the existence of the Environmental Kuznets Curve (EKC) of the EF for India. The study indicates that the income effect and increased policy focus on renewable energy usage can be expected to reduce India’s per capita EF in the long run. Moreover, India’s export sector has been traditionally less energy intensive, which reflects in our findings of export growth leading to a reduction in EF. Based on the empirical findings, this study recommends some policy insights that may assist India to effectively reduce its ecological footprint. Full article

The theme of the circular city is currently much debated in the literature as a possible strategy for achieving sustainability in urban areas. However, as a recent development it still has many features in the making, one of the most important being the issue concerning monitoring and the tool through which to achieve it. In the paper, therefore, the “indicator” tool is explored in depth. Metrics represent a fundamental and complex aspect that is foundational to measuring and quantifying the progress of results achieved with respect to the goals set. Currently, most existing indicators are associated with specific aspects of the circular economy; there have been few examples of indicators designed to assess the circularity of an entire city. The paper aims to identify priority themes and describe a set of indicators to be used at the urban level. In the absence of an established reference frame, themes and indicators were identified through a methodology starting with an extensive literature search and careful analysis, including statistical analysis, of the scientific literature as well as international and European strategies on the subject. A particular result of this research is the definition ofa minimum set of indicators common to all cities, which can be applied for comparative purposes. Full article

The impact of linear agri-food supply chains is progressively leading to ever wider socio-environmental and cultural repercussions, undermining the balance of territories and communities to the point of disrupting the entire planet’s health. Therefore, there is an urgent need for a paradigm change involving the agri-food sector, the economic sector, and local public policies, in the direction of a diffused ecological transition. In this scenario, the Circular Economy, supported by the adoption of a Systemic Approach, represents a useful operational tool to respond to complex transversal challenges, to reduce and enhance waste, minimize the use of new raw materials, and strengthen the territorial identity and relations among local stakeholders. This article describes a research project conducted for the Piedmont Region (Italy), through which it was possible to apply these innovative tools and approaches to five typical local agri-food chains (wine, dairy and cheese, rice, water, and bovine beef). Currently, at the Piedmontese level, concrete proposals for public policies capable of supporting the ecological transition of the local agri-food chains have not yet been developed, especially in terms of cyclicality of outputs and territorial co-evolution. For this reason, through the use of a multi-stakeholder approach, participatory mechanisms of local actors, and the analysis of several national and international case studies, the purpose of this research was to evaluate the possible enhancement of food waste and by-products, finally developing specific proposals for good practices and public policies capable of contributing to the achievement of the Piedmontese Regional Strategy for Sustainable Development.

This study examines the role of environmental knowledge, perceived consumer effectiveness, and willingness to sacrifice on travelers’ towel reuse behavior. Additionally, it tests whether environmental consciousness moderates the effect of environmental knowledge, perceived consumer effectiveness, willingness to sacrifice, and attitude towards towel reuse on actual towel reuse behavior. The proposed research model was tested using Amazon Mechanical Turk data. Using partial least square structural equation modelling, we analyzed the hypotheses. The results demonstrate that environmental knowledge, perceived consumer effectiveness, and willingness to sacrifice have significant influences on travelers’ towel reuse behavior. Additionally, findings about environmental consciousness indicate that high levels of environmental consciousness can help bridge the attitude-behavior gap. To bridge the gap between travelers’ attitude and behavior, managers should develop communication strategies to raise awareness and a sense of responsibility among them. Full article

Economy and ecology are two main aspects of human sustainable development. However, a comprehensive analysis of the status and trends of economic and ecological cognition is still lacking. Here, we defined economic and ecological concepts as cultural traits that constitute a complex system representing sustainability ideas. Adopting a linguistic ecology perspective, we analysed the frequency distribution, turnover and innovation rates of 3713 concepts appearing in China’s mainstream newspaper, People’s Daily, from 1946 to 2015. Results reveal that: (1) In the whole historical period, there were more economic concepts than ecological concepts both in amount and category. Economic concepts experienced stronger cultural drift than ecological concepts tested by the neutral model of cultural evolution; (2) popular economic concepts became more diversified, but popular ecological concepts became more uniform; (3) both economic concepts and ecological concepts attained more variation in their own disciplinary domains than in cross-disciplinary domains; and (4) as a platform of both giving information and opinion, a newspaper is subjected to cultural selection, especially reflected in the change in ecological concepts under the context of Chinese ecological civilization construction. We concluded with a discussion of promoting vibrant and resilient ecological knowledge in fostering sustainability activities and behaviours. Full article

Reasonable allocation of carbon emission rights aids in the realization of the goal of carbon emission reduction. The purpose of this paper is to examine how carbon emission rights in the power sector in the Yangtze River Economic Belt (the YREB) are distributed. The YREB spans China’s eastern, central, and western areas. The levels of development and resource endowment differ significantly across regions, resulting in great heterogeneity in the YREB provinces’ carbon emission rights distribution in the power sector. The ZSG–DEA model is used in this paper to re-adjust the power sector’s carbon emission quotas in each province to achieve optimal efficiency under the country’s overall carbon emission reduction target. The results show that: (1) In most provinces, the power sector’s initial distribution efficiency is inefficient. Only Zhejiang and Yunnan have reached the production frontier, with Jiangxi and Chongqing having the lowest distribution efficiency. In the future, we should concentrate our efforts on them for conserving energy and lowering emissions; (2) The initial distribution efficiency of the power sector in the YREB’s upstream, midstream, and downstream regions is considerably different. Most upstream and downstream provinces have higher carbon emission quotas, while most midstream provinces have less, implying that the power sector in the midstream provinces faces greater emission reduction challenges; (3) The carbon emission quotas of the power industry varies greatly between provinces and shows different spatial features over time. In the early stage (2021–2027), the carbon emission quota varies substantially, while for the later stage (2027–2030), it is rather balanced. Zhejiang, Jiangsu, Sichuan, and Yunnan are more likely to turn into sellers in the market for carbon emission trading with larger carbon emission quotas. While Jiangxi and Chongqing are more likely to turn into buyers in the market for carbon emission trading with fewer carbon emission quotas. Other provinces’ carbon emission quotas are more evenly distributed. To successfully achieve China’s emission reduction target by 2030, the YREB should promote regional collaboration, optimize industrial structure, accelerate technical innovation, establish emission reduction regulations, and provide financial support based on local conditions.

The traditional carbon-based approach towards sustainability has long caused the concepts of green and sustainable energies to be used interchangeably. Recent studies have tried to advance this archaic view by considering more aspects of sustainability. However, almost all major studies have been concerned with only the economic and environmental aspects of electricity generation, whereas the concept of sustainability is beyond these two criteria. In this paper, we seek to provide a methodology for a more comprehensive definition of electricity generation sustainability based on the lessons learned from previous studies and additional metrics suggested by them. The main characteristics of select electricity generation technologies were studied, and their environmental, economic, social, and technical criteria as well as the uncertainties associated with them were selected as the four major factors in our paper. It has also been argued that the utilization of regional resources in addition to the inherent characteristics of electricity generation technologies is vital in providing a realistic view of sustainability. Of the sustainability assessment methods previously introduced, the Relative Aggregate Footprint (RAF) method was used in conjunction with the previously selected criteria as the basis of the study due to its ability to incorporate additional criteria and regional considerations. As such, the framework for sustainability assessment presented in this research accounts for major criteria identified in the literature and takes the available regional resources that affect the feasibility of each electricity technology into account. This study paves the way for the presentation of new guidelines for the creation of more comprehensive electricity generation sustainability measures to distinguish between the concepts of green and profitable vs. sustainable energies to support the development of sustainable energy portfolios.

Livestock manure is a major source of the greenhouse gases (GHGs) methane (CH4) and nitrous oxide (N2O). The emissions can be mitigated by production of biogas through anaerobic digestion (AD) of manure, mostly together with other biowastes, which can substitute fossil energy and thereby reduce CO2 emissions and postdigestion GHG emissions. This paper presents GHG balances for manure and biowaste management as affected by AD for five Danish biogas scenarios in which pig and cattle slurry were codigested with one or more of the following biomasses: deep litter, straw, energy crops, slaughterhouse waste, grass–clover green manure, and household waste. The calculated effects of AD on the GHG balance of each scenario included fossil fuel substitution, energy use for transport, leakage of CH4 from biogas production plants, CH4 emissions during storage of animal manure and biowaste, N2O emissions from stored and field applied biomass, N2O emissions related to nitrate (NO3) leaching and ammonia (NH3) losses, N2O emissions from cultivation of energy crops, and soil C sequestration. All scenarios caused significant reductions in GHG emissions. Most of the reductions resulted from fossil fuel substitution and reduced emissions of CH4 during storage of codigestates. The total reductions in GHG emissions ranged from 65 to 105 kg CO2-eq ton−1 biomass. This wide range showed the importance of biomass composition. Reductions were highest when straw and grass–clover were used as codigestates, whereas reductions per unit energy produced were highest when deep litter or deep litter plus energy crops were used. Potential effects of iLUC were ignored but may have a negative impact on the GHG balance when using energy crops, and this may potentially exceed the calculated positive climate impacts of biogas production. The ammonia emission potential of digestate applied in the field is higher than that from cattle slurry and pig slurry because of the higher pH of the digestate. This effect, and the higher content of TAN in digestate, resulted in increasing ammonia emissions at 0.14 to 0.3 kg NH3-N ton−1 biomass. Nitrate leaching was reduced in all scenarios and ranged from 0.04 to 0.45 kg NO3-N ton−1 biomass. In the scenario in which maize silage was introduced, the maize production increased leaching and almost negated the effect of AD. Methane leakage caused a 7% reduction in the positive climate impact for each percentage point of leakage in a manure-based biogas scenario. Full article

This paper analyses the strategies implemented by listed Spanish companies that are leaders in their industrial environments to inform shareholders and the public about their circular economy projects. It uses content and textual approaches through the factorial correspondence analysis of all the information about the circular economy presented on corporate websites. The analysis of the 17,510 resulting terms suggests that companies prioritise discourses about a sustainable future, their commitment to the proper use of resources and the reduction or elimination of greenhouse gases. The sectors most sensitive to institutional pressures, such as oil and energy companies, are more active in disclosing the problems and desired solutions of their projects. Full article

The Slovak Republic does not meet the targets of the waste economy in the long run. In order to meet these objectives, it is necessary to make changes to the current system of municipal waste management. Building on an empirical analysis, this paper focuses on the evaluation of the production of municipal waste and the factors that influence the level of municipal waste sorting as a prerequisite for the maximal re-use, recovery, or recycling of municipal waste. The type of fee for municipal waste was confirmed as the most significant factor for the higher rate of municipal waste sorting, and pertinent recommendations were suggested according to the needs of Slovak municipalities.

Implementing climate policy goals, such as achieving climate neutrality by 2050, requires significant transformation of the mining sector—which for some countries and regions where mining is still the basis of the economy and part of the identity is very difficult and results in significant social and economic costs. Focusing on regional aspects and characteristics of the mining sector in Poland and its impact on energy security, the paper provides insight into the noticeable process of mining modernization in the globalized world economy through its transition from the industrial era to a knowledge-based economy and the impact of these changes on regional development. The described process is directly related to implementation of innovative and new technical concepts and technological solutions for the mining industry. The indicated changes imply the need to redefine operating principles and organizational models in the mining industry in order to build responsive solutions based on innovations—shaping modern (intelligent) mining of the future—while at the same time being part of the transformation of (post-)mining regions into a multi-industry region. All the described elements are proposed as supporting elements of the transformation process—to ensure full use of the technological and infrastructural potential during the energy transition process.

To facilitate the adoption of the circular economy (CE) in the architecture, engineering and construction (AEC) sector, some authors have demonstrated the potential of recent designs that take into account the sustainable management of an asset’s end-of-life (EOL), providing an alternative to the dominant designs that end with demolition. However, there is no review of the literature that encompasses a large range of sustainable designs in the current CE context. This paper provides a critical review of journal papers that deal with the barriers to implementing sustainable designs and approaches to the EOL management of assets that have the potential to fulfil the principles of the CE. Eighteen approaches related to prefabrication, design for change, design for deconstruction, reverse logistics, waste management and closed-loop systems were found. Through an analysis of the barriers that are common among these 18 approaches, we classified them into six different categories (organisational, economical, technical, social, political and environmental). Two Sankey diagrams illustrate the interrelation between the barriers, their categories and the 18 approaches. The diagrams clearly show that most of the barriers are common to multiple approaches and that most of the barriers relate to organisational concerns. The study gives a detailed map of the barriers that would help stakeholders from the AEC sector develop strategies to overcome the current obstacles in the shift to a CE. Full article
