This paper presents a comprehensive analysis comparing the implementation of electric and diesel buses for public transport services in the low-density area of the City of Jastrebarsko in Croatia. It utilizes a multidimensional approach and incorporates direct and indirect costs, such as vehicle acquisition, operation, charging, maintenance, and environmental impact costs during the lifecycle of the buses. The results show that, despite the higher initial investment in electric buses, these vehicles offer savings, especially when coupled with significantly reduced emissions of pollutants, which decreases indirect costs. However, local contexts differ, leading to a need to revise whether or not a municipality can finance the procurement and operations of such a fleet. The paper utilizes a robust methodological framework, integrating a proposal based on real-world data and demand and combining it with predictive analytics to forecast long-term benefits. The findings of the paper support the introduction of buses as a sustainable solution for Jastrebarsko, which provides insights for public transport planners, urban planners, and policymakers, with a discussion about the specific issues regarding the introduction, procurement, and operations of buses of different propulsion in a low-density area.

Background: The current food system is unsustainable, making it essential to address the issue globally through adequate policies and sustainable development goals. The European Union aims to dedicate 25% of farmland to organic farming by 2030 to promote sustainable practices. Warsaw is the first Polish city working on an urban sustainable food policy; however, there is limited data on the sustainable food system (SFS) and organic sector available. Objectives: This research examines whether consumers in Warsaw who prefer organic food also display other sustainable characteristics and awareness, reflected in their food choices, dietary habits, and other food-related behaviors. Methods: A household survey (HHS) was conducted as part of the SysOrg project, focusing on evaluating the sustainability of food systems in Warsaw in the areas of diet and organic food. The clusters of respondents, grouped by the self-declared proportion of organic foods in their diets, were analyzed and compared, and in addition, correlation analyses of the share of organic food in diets and other sustainability parameters were performed. Results: The study of 449 respondents indicates that Warsaw is at an early stage of the organic transformation, with the largest group of respondents declaring a 1–10% share of organic products in their diet. There were significant differences in dietary choices, sustainability awareness, and food selection habits and motivations among various consumer groups depending on their organic food share. Conclusions: Overall, this study’s findings highlight a link between organic food consumption and certain sustainable behaviors, suggesting potential for organic consumers’ contribution to a sustainable transformation. The study offers valuable insights into the existing knowledge gap regarding the behaviors of organic and sustainable consumers in Warsaw. Furthermore, despite the non-random nature of the sample limiting the generalizability of findings, it serves as a preliminary resource for other European cities that are formulating food policies and incorporating Green Public Procurement (GPP) into their procurement processes, especially for municipalities within the Visegrad Group.

Smart Land Use Planning (SLUP) has gained increasing attention in urban development, yet few studies examine its implementation from an urban governance perspective. This study investigates municipal SLUP project characteristics, their spatial distribution, and intercity cooperation networks by analyzing 3689 SLUP government procurement contracts in China’s Yangtze River Delta urban agglomeration. Using the Latent Dirichlet Allocation model, this study identified four main SLUP project types: real estate management, land resource protection, land use planning, and geographic information services. Spatial analysis revealed significant imbalances across cities, with SLUP projects concentrated in central cities while other cities heavily depend on intercity cooperation for technical support and services. Network analysis showed a core–periphery structure, with industrial structure and institution similarities significantly facilitating cooperation, while geographic distance and cultural similarity had limited impact. Future research should expand data sources to enable cross-regional comparative analysis. This study offers empirical evidence for policymaking in the implementation of SLUP and regional coordinated development. Full article

Driven by the path of ecological transition, municipal solid waste management is now more than ever at the center of debates on the most efficient delivery methods. Although competition policy advocates subdivision into lots to facilitate medium-sized enterprise participation, in some cases—notably when substantial investments are required to achieve circular economy and sustainable development goals—a single-operator model may prove more efficient. Using a mixed research approach that integrates empirical evidence and market analysis, this study examines the relevance of cost curves, transaction costs, and market structure in determining the optimal service delivery model. The findings indicate that for large cities, consolidating MSW management services under a single contract yields significant cost advantages due to economies of scale and scope and is better suited to supporting the investments necessary for circular economy objectives. Practical implications for local policymakers highlight the need to assess utility sector policies carefully. Decisions at the local level should account for the interplay between the economic environment and the role of industrialization and economies of scale in fostering sustainable development. We suggest policymakers design policies that balance market efficiency with equitable access to services while also considering the scale of service provision, as it influences sustainability and economic resilience.

This study evaluates the potential impact of new energy communities (ECs) on the electric infrastructure within the Italian regulatory framework using publicly available information on reverse power flow metrics in high-voltage (HV)/medium-voltage (MV) interfaces and calculating the municipal energy balance. The current legislation is incentivizing EC configurations where members connected to the same HV/MV interface are sharing energy, predominantly produced by new-generation units. To identify critical territories, primary substation service areas are overlapped with reverse flow occurrences, focusing on cases that exceed 5% of the year. The output is utilized to indicate the municipalities that fall within these areas. The municipalities deemed critical are further evaluated, defining a Key Performance Index (KPI) as the ratio of local production capacity to consumption, with generation data procured by the national database on production units and load estimates derived from provincial cumulative data, adjusted using census information on population and employment with a municipal resolution. A piecewise linearization approach is employed to examine the cumulative distribution function (CDF) of the KPI, enabling a traffic light-like criticality classification. The results provide a relative assessment and highlight municipalities with a higher risk of detrimental impact of EC adoption within the current framework. The outcome is presented as a national georeferenced map illustrating the municipal criticality. This emphasizes the need for revising the regulative framework, potentially enabling the utilization of existing generators in critical areas and leveraging load flexibility and increased local energy sharing to procure benefits from EC adoption.

Food from home can increase feelings of belonging and act as a source of comfort for people who move to another country and their children. Nevertheless, people who move elsewhere often start taking over dietary elements of the host culture, a dynamic process referred to as food acculturation. This paper argues that this process is not only related to identity negotiations and emotional connections, but that food choices are also shaped by everyday practical realities. Using a social practice theory-inspired approach, focusing on the elements of material, competence, and meaning, this study investigates the food provisioning practices of eighteen people with a migration background through semi-structured interviews. The study’s findings show that procuring typical ingredients from one’s home country is relatively easy in the study area of Almere, the Netherlands. Cooking skills, however, are more difficult to maintain and transfer to the next generation. Finally, the meaning of eating foods from home lies in connecting these foods to celebrations and get-togethers. In regular day-to-day meals, respondents often opt for more convenient dishes, either from their root cuisine or from Dutch or other food cultures. The paper concludes that respondents’ eating patterns balance cultural traditions with practical constraints of modern life, as people navigate their food routines while making practical choices that align with their daily routines and social environments. Municipalities, social services, and community initiatives could direct more attention to celebrating the culinary heritage that connects people from diverse migration backgrounds by organizing exchanges and get-togethers and fostering culturally appropriate food environments.

Smart cities leverage information and communication technologies to enhance urban life quality, essential in densely populated environments requiring comprehensive planning. A critical area in urban settings is food production and delivery, where effective management becomes vital. New technologies can assist, but require models that support innovative production and commercialization methods. This study proposes an integration model between family farming—producers of organic food—and urban areas—consumers of these products. The model focuses on the management of organic food production and delivery to meet urban demands, serving as a tool in the transformation of these areas into smart municipalities. Additionally, this study suggests an alternative certification method for organic food production within family farming. A systematic literature review was conducted using the Methodi Ordinatio methodology. Content analysis of the selected articles identified strategies cities can adopt to promote organic certification, emphasizing transparent governance, public food procurement policies, and participatory certification systems. The proposed model aims to reduce bureaucracy and improve family farmers’ income, aligning with several Sustainable Development Goals: SDG 2 (Zero Hunger), SDG 8 (Decent Work and Economic Growth), SDG 11 (Sustainable Cities and Communities), SDG 12 (Responsible Consumption and Production), SDG 15 (Life on Land), and SDG 17 (Partnerships for the Goals).

This article explores the relationship between local authorities (mainly municipal organisations) and a central purchasing body (CPB). It critiques, from an agency theory perspective, the difficulties in aligning socio-economic goals of multiple municipal organisations with the pursuit of procurement goals by the CPB. The aim of this study is to explore which solutions, (governance mechanisms) for agency problems within a Dutch municipality–CPB relationship, are critical in aligning socio-economic goals within a collaborative public procurement (CPP) setting. The quantitative analysis of data from a questionnaire was used to conduct an explorative factor analysis (EFA). The questionnaire was issued to all municipalities in the Netherlands. Grounded on the EFA, the underlying factors within five categories of governance mechanisms for agency problems were recognised. Besides supporting the existing theory, this study provides additional knowledge in the field of agency theory and collaborative public procurement (CPP). The study resulted in the development of a comprehensive measurement scale to conduct research based on agency theory within the context of CPP governance and specifically in the area of central purchasing bodies. The results of this study are applicable in practise on an administrative and management level. Municipal organisations that initiate and/or govern a central purchasing body can take the results of this study into account to develop new standards on the further development of the CPB. At a managerial level, this study provides useful insight for decision-makers in municipal organisations to improve the way in which a CPB executes collective tenders at hand and determine if the joint approach delivers the best results in terms of their procurement objectives.

With burgeoning economic development, a surging influx of greenhouse gases, notably carbon dioxide (CO₂), has precipitated global warming, thus accentuating the critical imperatives of monitoring and predicting carbon emissions. Conventional approaches employed in the examination of carbon emissions predominantly rely on energy statistics procured from the National Bureau of Statistics and local statistical bureaus. However, these conventional data sources, often encapsulated in statistical yearbooks, exclusively furnish insights into energy consumption at the national and provincial levels, so the assessment at a more granular scale, such as the municipal and county levels, poses a formidable challenge. This study, using nighttime light data and statistics records spanning from 2000 to 2019, undertook a comparative analysis, scrutinizing various modeling methodologies, encompassing linear, exponential, and logarithmic models, with the aim of assessing carbon emissions across diverse spatial scales. A multifaceted analysis unfolded, delving into the key attributes of China’s carbon emissions, spanning total carbon emissions, per capita carbon emissions, and carbon emission intensity. Spatial considerations were also paramount, encompassing an examination of carbon emissions across provincial, municipal, and county scales, as well as an intricate exploration of spatial patterns, including the displacement of the center of gravity and the application of trend analyses. These multifaceted analyses collectively contributed to the endeavor of predicting China’s future carbon emission trajectory. The findings of the study revealed that at the national scale, total carbon emissions exhibited an annual increment throughout the period spanning 2000 to 2019. Secondly, upon an in-depth evaluation of model fitting, it was evident that the logarithmic model emerged as the most adept in terms of fitting, presenting a mean R² value of 0.83. Thirdly, the gravity center of carbon emissions in China was situated within Henan Province, and there was a discernible overall shift towards the southwest. In 2025 and 2030, it is anticipated that the average quantum of China’s carbon emissions will reach 7.82 × 10² million and 25.61 × 10² million metric tons, with Shandong Province emerging as the foremost contributor. In summary, this research serves as a robust factual underpinning and an indispensable reference point for advancing the scientific underpinnings of China’s transition to a low-carbon economy and the judicious formulation of policies governing carbon emissions.

Alternative forms of food procurement have increased in consumer popularity since the occurrence of food price inflation and the ongoing recession in the U.S. The present study explores predictors such as food engagement, food-related COVID-19 concerns, and the importance of sustainable foraging practices as determinants for U.S. consumers’ preferences for food foraging. Two scenarios are investigated, the preference for food foraging over growing food and food foraging over regular food buying. The study is based on an online consumer survey (n = 401) and used partial least square structural equation modeling (PLS-SEM) for the data analysis. Results indicate that food engagement is the strongest predictor for both foraging over buying and foraging over growing scenarios. However, food-related COVID-19 concern appears to only be relevant for the foraging over buying scenario and the importance of sustainable growing practices is only relevant for the foraging over growing scenario. These findings are important because they indicate the attitudinal triggers of food foraging and are therefore of relevance to foraging communities and managers in municipalities, food retail, and horticultural businesses who are associated with traditional and alternative forms of food procurement.

Public food procurement has been emphasized as a powerful tool to promote a healthier and more sustainable food system, but there is still a long way to go to reach full potential. This study aimed to investigate practices and opportunities for sustainable and healthy public food procurement. A qualitative cross-sectional study was performed among Danish municipalities and regions stratified and randomly selected to cover standard practice (n = 17). In addition, interviews were performed among selected best-practice municipalities (n = 5) providing examples of ambitious goals and well-defined processes for obtaining sustainable food procurement. Large differences were observed in the cross-sectional analysis in relation to policy support and goals for sustainable food procurement, including organic purchase. Generally, there was a great attentiveness to reduce food waste and many valued the use of local food, especially among rural municipalities, whereas experience with climate impact reduction and shifts towards more plant-based menus was still in an early implementation stage. Results suggest a possible synergy effect between the use of organic food and efforts to reduce food waste and climate impact and emphasize the importance of local government policies to promote healthy and sustainable food procurement. Enabling factors to move sustainable food procurement forward are discussed. Full article

Sports centres constitute major energy consumers. This article presents the proposed energy performance upgrade process and the achieved results for the municipal sports centre in Arkalochori, Greece. The facility consists of a swimming pool centre, an outdoor 8 × 8 football court, and two tennis and basketball courts. It operates with considerably high energy consumption due to the lack of any measure towards its energy efficiency improvement since its initial construction in 2002. Due to the significantly high heating cost, the swimming pool centre remains operative only during the summer period. The energy performance upgrade of the facility was holistically approached through all possibly applicable passive and active measures: insulation of opaque surfaces and replacement of openings, construction of a new, bioclimatic enclosure for the swimming pool’s centre and conversion of the current outdoor facility to an indoor one, installation of heat pumps for indoor space conditioning and swimming pool heating, installation of a solar–combi system for domestic hot water production, upgrade of all indoor and outdoor lighting equipment and installation of a photovoltaic plant on the new enclosure’s roof for the compensation of the remaining electricity consumption. With the proposed measures, the municipal sports centre is upgraded to a zero energy facility. The payback period of the investment was calculated at 14 years on the basis of the avoided energy procurement cost. The swimming pool’s centre operation is prolonged during the entire annual period. This work has been funded by the Horizon 2020 project with the acronym “NESOI” and was awarded the public award of the “Islands Gamechanger” competition of the NESOI project and the Clean Energy for EU Islands initiative.

LCA methodology is often used in public procurement decision making. The European Commission introduced Life Cycle Costing (LCC) in 2014 to support this methodology. LCCs take into account costs incurred during a service, work or product’s lifetime. Application management techniques of LCC offer a better awareness of the factors that influence the resources and costs in the case of procurements. The identification of the factors that influence the costs is the main key of the LCC tool. In such a way, the life cycle management is focused on efficient purchasing. The awareness levels of the LCC criteria influence the cost and will also highlight other aspects of existing products that could benefit from the involvement of life cycle management. Taxi transport services (as an alternative to public transportation) are a sector of the economy with a good income when acquisitions are properly carried out. When the acquisitions are analyzed, governmental and local regularizations should be taken into account. Today, cities, as well as small towns, look forward to improving the quality of life of the citizens and reducing pollution. The acquisitions of buses/cars for public use must be carried out with respect to the required performance of the cars. On the one hand, the municipality should be in line with the European Commission’s policy; on the other hand, it should be in line with the state’s public procurement requirements. An acquisition must also be reasonable in terms of price, lifetime, environmental impact, circular economy and meeting citizens’ needs. The goal of this paper was to analyze the acquisition of cars for taxi services from the perspective of public procurements. The study was performed with the help of the Taxi LAL company from Bacau County. The LCC techniques were applied to identify the most “acceptable” as well as the most “profitable” choices for taxi services. For a better understanding of the problem, within the present paper the mechanism of cost assessment for a product modernization was exemplified. Full article

This article examines the establishment and publication of green plans and green public procurement (GPP) policies in Japanese municipalities. The purpose of the study was to investigate these green policymaking initiatives from a contingency theory perspective. The first research question examined contextual factors for green policymaking. The second research question focused on barriers and enablers. For RQ1, through hypothesis testing and a regression analysis (n = 1663), we found that green policymaking differs by organization location, organization size, and organizational green capabilities. More specifically, we identified prefectures where municipalities score relatively higher as well as lower. Second, we found that larger (vs. smaller) municipalities undertake more (vs. less) green policymaking initiatives. Third, we observed that organizations with more (vs. less) green capabilities develop more (vs. less) green initiatives. For RQ2, through a descriptive and cluster analysis, we identified dominant barriers and enablers to establishing a GPP policy. The dominant barriers include a lack of information, lack of staff, and cost concerns, whereas manuals and example forms are important enablers. These findings are highly relevant to understanding and supporting green policymaking in Japanese municipalities. Full article

Since the occurrence of COVID-19 and food price inflation, alternative forms of food procurement increased in popularity. The present study is dedicated to urban foraging and aims to explore key factors driving food foraging behavior in the U.S. Two specific foraging behaviors, namely “leaving food behind” or “taking it all”, have been investigated in a gardening and non-gardening location. Leaving food behind is crucial to sustainable foraging practices, as it allows plants and ecosystems to recover and promotes fairness in foraging communities. Data was procured from an online consumer survey and analyzed using SmartPLS 4, which allowed the use of partial least square structural equation modeling (PLS-SEM). PLS-SEM is particularly suitable for complex exploratory studies as it does not require distributional assumptions. Results indicate that nature and food attitudes predict attitudes toward urban foraging. Foraging attitudes, such as food foraging is challenging and food foraging benefits people and the planet, which are the most important drivers for taking or leaving behaviors in both types of locations. These findings are of relevance to managers in municipalities, landscape designers, horticultural businesses, and other stakeholders who create, shape, and govern landscapes used for food foraging.
