A spotlight has been cast on the necessity to reduce construction and demolition waste and prioritise reuse and high-quality recycling. This work centres on selective demolition and design for deconstruction (DfD) as means of achieving these goals. A literature review is carried out, with the two-fold aim of assessing the state of the art in life cycle assessment studies on this topic and developing a taxonomy of applicable selective demolition and DfD solutions, framing it within the context of policy development in the EU. Available measures are identified for different building structural typologies (concrete, timber, masonry, steel), at the material and element level, providing a comprehensive overview of current and developing technologies. A taxonomy is proposed to support users in the identification of available measures and to link the effects thereof in terms of circularity. A literature-based quantitative assessment of current and potential reuse material rates is provided, together with the greenhouse gases (GHG) emission savings associated with reuse, in order to describe the present situation and highlight the potential for improvement. Reuse potential is found to vary between 0%–80%, depending on material and source; current European reuse rates are estimated &lt;15%. In terms of C-footprint, reuse appears beneficial in most cases. The additional GHG savings from reuse relative to alternative end-of-life options span from 1.30 (gypsum) to 5464 (expanded polystyrene) kg CO_2-eq. per tonne of material managed.</p></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"15 ","pages":"Article 100153"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666916124000069/pdfft?md5=d974fd32e559238ecae5dd354d711bc2&pid=1-s2.0-S2666916124000069-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140271354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As organizations strive to increase their IT equipment procurement, there is growing concern about its negative environmental impact. This increased environmental consciousness has made it crucial to adopt a sustainable approach to IT equipment procurement that considers factors such as carbon emissions and End-of-Life (EOL) cycle of equipment. Therefore, this research developed a prediction model for IT equipment procurement as the basis of knowledge for an Intelligent Decision Support System based on carbon emissions and EOL phase. The primary aim of this study is to develop a prediction model for IT equipment procurement that allows for the estimation of carbon emissions associated with the equipment. Several models, including K-Nearest Neighbors, Decision Tree, Polynomial Regression, Autoregressive Integrated Moving Average applied to historical procurement data, and Long Short-Term Memory, were tested to determine the most effective. The developed model has proven successful in predicting IT equipment procurement for future periods, achieving an impressive R-squared score of 0.80. This high accuracy demonstrates the model’s effectiveness in assisting organizations to make well-informed and sustainable decisions regarding IT equipment procurement based on precise predictions and estimated environmental impacts. The developed prediction model is expected to optimize the procurement process by considering environmental aspects like carbon emissions and equipment lifecycle.</p></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"16 ","pages":"Article 100151"},"PeriodicalIF":0.0,"publicationDate":"2024-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666916124000045/pdfft?md5=1d025b3cbe96b0a3167ef6d1a7730513&pid=1-s2.0-S2666916124000045-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139732559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

City administrators currently lack a data-driven framework for allocating resources during constraint scenarios, leading to subjective decisions. Existing literature lacks objective solutions for managing city-scale green spaces, each with its distinct characteristics. Another challenge is handling varied spatial scales required for urban applications. This study proposes a novel goal programming-based model for urban green space management wherein multiple benefit objectives, such as conserving sequestered carbon in trees and enhancing quality and accessibility of parks, as well as handling demand constraints on available resources like water and personnel, are included. The proposed method was demonstrated in two cities with diverse conditions, Berlin and Melbourne, and evaluated on various benefit metrics, such as allocated green space units, resources consumed, and goals achieved. The model was analyzed with resource allocation decisions and goals at different spatial scales. The highest benefit achievement and resource allocation were observed when resources were allocated at the sub-district scale with a city-level target. Alternatively, setting targets at the district level provided a more even resource distribution; however, at the cost of reduced overall benefits. Results show that the proposed method increased the total benefits gained while effectively balancing conflicting goals and constraints. Additionally, it allows incorporating the city’s preferences and priorities, offering a scalable solution for informed decision-making in varied urban applications.

In recent years, rapid growth in China’s new energy automotive industry has significantly contributed to transportation decarbonization. However, environmental challenges in producing and recycling electric vehicles (EVs) may limit emission reduction benefits. In this study, we establish a comprehensive life cycle assessment model for vehicles to analyze the gap in air pollutant and greenhouse gas emissions between electric vehicles and internal combustion engine vehicles (ICEVs). Based on this model, the environmental benefits of further promoting electric vehicles in China are evaluated. Results reveal that, compared to ICEVs, EVs reduce life cycle emissions of CO₂ by 12%, NO<em>x</em> by 69%, and VOCs by 9%. Primary constraints on EVs in emission reduction are traced to raw material and component production, notably lithium batteries. By 2025, under the low carbon EVs policy scenario, widespread EV production and sales could cut lifecycle emissions by 3.55 million tons of CO₂, 3,6289 tons of NO<em>x</em>, and 4315 tons of VOCs. During the driving stage, these indicators contribute 495%, 124%, and 253%, respectively, to total emission reduction throughout the lifecycle. This study conducts a comprehensive lifecycle analysis of greenhouse gases and various air pollutants for Chinese EVs. It integrates the latest market trends, application progress, and policy guidelines into scenario design, identifying key sources and indicators of atmospheric pollution in the EV production chain. The findings offer valuable policy insights into China’s role in the global emission reduction process.</p></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"15 ","pages":"Article 100148"},"PeriodicalIF":0.0,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S266691612400001X/pdfft?md5=4a4aed4f52d9c00218dece71de9912cc&pid=1-s2.0-S266691612400001X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139549091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Saudi Arabia, where 60% of the urban water supply relies on energy-intensive desalination processes, the average per capita water consumption rate of 300 L/day is one of the highest worldwide. This study investigates potential behavioral patterns in residential water consumption among households in Saudi Arabia. A segmentation approach is employed to classify residents into clusters and evaluate their potential water consumption behavioral patterns. Data from 618 households were collected via a structured questionnaire and analyzed using descriptive statistics, principal component analysis (PCA), and cluster analysis (CA). Participants were categorized into six segments based on the relationship between their behaviors and water consumption derived from the factor analysis. The outcomes of PCA and CA analyses indicate a relationship between respondents’ socio-demographic factors and their potential behavioral patterns in residential water consumption. The findings highlight that education, household size, income, housing type, age, and nationality, in increasing order of significance, are the key factors influencing household water consumption and conservation tendencies. The paper concludes that comprehending residential water consumption patterns is crucial for effective interventions, social marketing strategies, and communication campaigns for behavioral changes.
