Modelling results found a strong influence of household characteristics on the normal usage of resilience hubs, while individual characteristics were more influential on hub usage as a temporary shelter. No clear patterns of variables influenced mode choice (travel to/from hubs), except the insignificance of resilience hub usage (i.e., trip purpose) for normal conditions. For mode, the results showed a strong preference for private vehicles, yet still a relatively high multi-modal split (e.g., walking, transit, shared mobility). Residents also preferred highly localized resilience hubs with a variety of transportation options, services, and amenities.

According to projections, tourism in Malaysia makes it more difficult to reach carbon neutrality. Traveler numbers along with fossil fuel energy use, economic growth, financial development, gross fixed capital formation, and population have a positive association with long–term carbon emissions. However, the findings revealed a negative link between renewable energy consumption and carbon emissions. Several methods, including Canonical Cointegration Regression (CCR), Dynamic Ordinary Least Squares (DOLS), and Fully Modified Ordinary Least Squares (FMOLS), were used to independently verify the results.

Firms in such industries need to make frequent design changes to incorporate innovations, and the effort to keep up with the rate of technological change often leaves little room for the consideration of product reuse. In this paper, we study the design for reusability and product reuse decisions in the presence of both a known rate of incremental innovations and a stochastic rate of radical innovations over time. We formulate this problem as a Markov Decision Process. We provide both analytical and numerical results, the latter based on over 425,000 problem instances generated over the entire range of model parameters. Our steady-state results confirm the conventional wisdom that a higher probability of radical innovations would lead to reductions in the firm’s investments in reusability as well as the amount of reuse the firm ends up doing. Interestingly, the design for reusability decreases much more slowly than the actual reuse. We identify some specific scenarios, however, where there is no tradeoff between the possibility of radical innovations and the firms reusability and reuse decisions. Through computational experiments, we also provide insights into the negative impact of radical innovations on firm profits, but show that the environmental impact of increased radical innovation is not necessarily negative. Our results also have several implications for policy makers seeking to encourage reuse. In particular, increasing end-of-life costs through take-back legislation is a safe and effective policy lever.</p></div>","PeriodicalId":101193,"journal":{"name":"Sustainability Analytics and Modeling","volume":"3 ","pages":"Article 100021"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49710348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, packaging solutions provide functional properties that help to preserve fresh produce and protect food from external damage. Given these trade-offs, it can be very challenging for retailers to make the right decisions, lowering their environmental impact. This is further complicated by the complex nature of inventory dynamics in the case of perishable products, as multiple factors can impact food waste and the environmental impact at the retailer. This research proposes a simulation model to investigate the effect of packaging as well as a variety of other factors on profit, waste and the environmental impact of products. For this purpose, the environmental impacts of three different products and their corresponding packaging solutions were quantified using a life cycle approach, and a number of experiments considering different demand patterns, service level requirements, batch sizes and order policies were carried out. The findings of this research are manifold, highlighting the importance of considering inventory and packaging decisions within an integrated framework. Moreover, while the shelf life extension obtained from the use of packaging has clear economic benefits due to the resulting lower waste levels, the environmental impact varies depending on the considered products, packaging material and environmental indicator.</p></div>","PeriodicalId":101193,"journal":{"name":"Sustainability Analytics and Modeling","volume":"3 ","pages":"Article 100020"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49710346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To understand the decision process, this paper employs a double hurdle model to explore the factors affecting farmers’ adoption and willingness to pay for BDMs using the sample data from China. The results show farmers follow a two-stage decision-making process, farmers have to overcome the first hurdle, i.e., adoption or non-adoption, and then decide how much they are willing to pay for BDMs. The role of technology-specific characteristics is more important than adopter-specific characteristics in the adoption of BDMs. Understanding the impact of factors on farmers’ decision-making process can assist policymakers in designing programs, specifically tackling difficulties confronting farmers at different stages of decision-making.</p></div>","PeriodicalId":101193,"journal":{"name":"Sustainability Analytics and Modeling","volume":"3 ","pages":"Article 100016"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49710344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This analysis aims to investigate how retailer heterogeneity in terms of shop characteristics and social association influences bag use behavior and compliance with the plastic bag ban in Nepal. This study based on the 1300 retailers’ plastic bag use data in three different plastic bag ban scenarios from 13 municipalities of Nepal shows that retailers’ response to the ban depends on their shop type, the nature of the goods they sell, and their social association. In addition, retailers' perception also affect their response to the plastic ban decision. Their perception of the performance of regulatory authority is likely to affect their compliance. Similarly, retailers who consider that the municipality has strong enforcement in place, tend to cooperate with the ban.

This has led to numerous studies in this field of research, ranging from environmental impact investigation of building components (walls, insulation layers) to the carbon emission analysis of several buildings and networks, open spaces, and transportation facilities on a broader scale. This study aims to contribute to the field of research by conducting a comprehensive analysis of existing literature studies on varying scales. The primary objective is to determine whether the current studies have adequately addressed the gap in knowledge by effectively implementing Life Cycle Assessment (LCA) methodologies throughout the entire lifecycle of buildings while ensuring a sufficient level of detail and reliability in their findings. Additionally, this investigation seeks to evaluate the extent to which urban-scale LCA analyses have been undertaken in previous literature and assess the accuracy of the corresponding results. Furthermore, the study intends to identify the necessary measures that can be implemented to enhance the value and validity of these research outcomes. Ultimately, the findings of this research endeavor will identify the shortcomings and gaps in the current body of knowledge, thereby facilitating the development of a roadmap for future studies in this field of research. The gap analysis of this research field reveals important findings. Firstly, only 9% of previous studies have examined the entire urban scale, highlighting a significant research gap that should be addressed in future studies. Secondly, the bottom-up approach used in many studies introduces substantial uncertainty, necessitating improved modeling and uncertainty analysis. Thirdly, the building-by-building approach, while comprehensive, is time-consuming and costly, calling for research on enhancing its efficiency. Additionally, future studies should consider stock evolution beyond buildings, incorporate multiple LCA indicators, and integrate LCA with life cycle costing (LCC) in urban scale assessments. These identified gaps present promising avenues for future research in built environment LCA.</p></div>","PeriodicalId":101193,"journal":{"name":"Sustainability Analytics and Modeling","volume":"3 ","pages":"Article 100026"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49710324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The typical logistics network structures and associated product flows are identified and systematized that represent the supply chains of producers, wholesalers and retailers, as well as their vertical integration. These supply chain networks are analyzed in terms of characteristics and context-specifics and finally transferred to a mathematical model formulation. We find that direct deliveries from producers to retailers are preferred despite production-related lead times of several months or more because of shorter transportation times and therefore better product quality. Wholesalers are mostly used to compensate for product surpluses or deficits, and can offer short lead times. Our results show that the whole sector is dependent on reliable information about the market situation that is needed for accurate planning among the uncertainties the sector faces regarding aspects such as quality fluctuations, pests, trends in demand, and weather impacts on plant growth and final customer demand.
