Integration of life cycle sustainability assessment indicators in different energy sectors

Despite the increasing number of studies analysing sustainability performance in energy-related field, most of the existing papers present the results of particular dimensions separately. A number of methods have been identified to integrate individual LCSA indicators and determine one final sustainability score which could be a relevant support for decision-makers to rank scenarios being compared at the interpretation phase. In the current stage, none of the proposed methods seem to be in a leading position. The integration of sustainability indicators still suffers from the lack of harmonisation concerning the selection and definition of impact categories to be analysed, as well as specific procedures that would allow the results to be reliably compared. The procedures often assume arbitrarily determined weights of importance for aggregating environmental, economic and social scores, which can raise controversy. The development of noncontroversial methods to integrate LCSA indicators is also recommended from the perspective of future standardisation.

Life Cycle Sustainability Assessment of Buildings: A Scientometric Analysis

The significant environmental impact of the built environment, particularly concerning energy use, carbon emissions, and material consumption, coupled with its economic and social implications, has driven the demand for sustainable buildings. Life Cycle Sustainability Assessment (LCSA) offers a comprehensive approach to evaluating sustainability performance by integrating environmental, economic, and social dimensions across the building life cycle. However, the application of LCSA frameworks in the buildings sector remains limited due to the challenges in harmonizing different sustainability dimensions and addressing methodological inconsistencies. This study employs a scientometric analysis to systematically examine the research landscape on LCSA for buildings. Bibliographic records from the Scopus and Web of Science databases (1999–2024) were systematically analyzed using science mapping techniques and tools, including VOSviewer, CiteSpace, and Gephi. The analysis identifies key research trends, conceptual developments, influential academic sources, and collaboration patterns at the country level. The findings reveal a multi-faceted research landscape characterized by a predominance of environmental assessments, increasing attention to economic and social dimensions, the development of BIM-related methodologies, and emerging trend towards dynamic LCSA. Persistent barriers include insufficient standardization of methodologies, limited data availability, and the fragmented incorporation of the environmental, economic, and social dimensions of sustainability. The findings emphasize the need for advancing LCSA frameworks to achieve more effective integration of the triple bottom line, enabling robust decision-making and advancing sustainability in the built environment.

Future Risk from Current Sustainability Assessment Frameworks for the Resource Sector

This paper introduces a comprehensive sustainability assessment framework integrating Life Cycle Sustainability Assessment (LCSA) with Scenario Planning and Sensitivity Analysis, using the alumina industry as a case study. Current sustainability frameworks often focus narrowly on carbon emissions, neglecting broader environmental and social impacts, such as biodiversity loss, land rehabilitation, and social equity. By combining LCSA with forward-looking Scenario Planning, the proposed framework provides a multi-dimensional assessment, enabling industries to anticipate future challenges and adapt to technological, regulatory, and market changes. The analysis of Australia’s alumina production under Net-Zero and Accelerated Net-Zero scenarios demonstrates significant decarbonisation potential, achieving up to 97% emission reductions while improving energy efficiency by 50%. Despite these advances, indicators like biodiversity preservation and social equity remain insufficiently addressed, underscoring the need for a more holistic, industry-specific approach. Future research directions include improving measurement methods for ecological and social indicators, exploring policy mechanisms to enhance adoption, and establishing partnerships with international bodies like the Aluminium Stewardship Initiative to ensure global adaptability. The increasing adoption of Environmental, Social, and Governance (ESG) methodologies highlights the need for comprehensive impact management and higher standards of governance. Although the proposed framework has notable strengths, its reliance on region-specific quantifiable indicators and simplified models limits its global adaptability. The proposed framework advocates for a mandatory, independent regulatory mechanism to drive balanced, transparent reporting, supporting industries in achieving transformative sustainability outcomes.

Life Cycle Sustainability Assessment of Microbially Induced Calcium Carbonate Precipitation (MICP) Soil Improvement Techniques

Microbially induced calcium carbonate precipitation (MICP) is a biomediated ground improvement technology that uses ureolytic bacteria to precipitate calcium carbonate minerals to improve the strength and stiffness of soils. MICP can be mediated by either augmented non-native or stimulated indigenous microorganisms, resulting in biocemented soils and generated aqueous ammonium (NH4+) byproducts. Although the process has been extensively investigated, the fate and transport of generated NH4+ byproducts has posed an environmental challenge and to date, their associated environmental impacts have remained poorly understood. In an effort to better quantify process impacts, a large-scale experiment was conducted involving three 3.7 m long soil columns, wherein three different ureolytic biocementation treatment approaches were employed. A life cycle sustainability assessment (LCSA) was performed to compare the environmental impacts and costs of these different MICP treatment approaches as well as evaluate the potential environmental benefits of NH4+ byproduct removal using post-treatment rinsing. The objective of this paper is to present the results of the LCSA study. LCSA results suggest that when treatments are consistent with those performed in this study, stimulation can be more sustainable than augmentation, and the use of lower ureolytic rates can further reduce process environmental impacts by achieving greater spatial uniformity and extent of biocementation. The LCSA outcomes also illustrate tension between the environmental benefits afforded by NH4+ byproduct removal and the life cycle impacts and costs associated with this removal. For the specific testing conditions, the injection of 1.8 pore volumes of rinse solutions to remove generated NH4+ byproducts following biocementation was found to minimize environmental impacts; however, further refinement of such approaches will likely result from future field-scale applications.

Assessing Urban Freight Tours: A Machine Learning and Life Cycle Sustainability Assessment Approach for Logistics Management

ABSTRACTThe main aim of this study is to assess urban freight tours through integrating machine learning with the Life Cycle Sustainability Assessment (LCSA). The research captures supply chain operations using the Gradient Boosting Regressor (GBR) model with real‐time data from surveys and Global Positioning System (GPS) tracking. These predictions were analysed using LCSA to assess the sustainability impacts of Hydrogen Fuel Light Commercial Vehicles (HFLCVs) and Electric Light Commercial Vehicles (ELCVs) compared to traditional fuel‐based vehicles. HFLCVs show remarkable reductions in ecosystem and health damage by 58% and 61%, indicating substantial environmental and health benefits. Findings suggest that strategic investment in hydrogen‐fuel and electric LCVs can significantly decrease operational costs and environmental impacts, making them crucial for advancing sustainable urban logistics. This research highlights the benefits and possibilities of using an integrated data‐driven approach to achieve urban sustainability, thus creating an urgency to shift policies favouring green urban freight systems.

Sustainability Assessment of Employing Chemical Recycling Technologies on Multilayer Packaging Waste

While multilayer plastic is difficult for recycling, innovative technologies and tactics are being developed to improve the process. New technologies in chemical recycling show promising results; however, the net improvement brought to the environment, economy, and society should be assessed for their wider adoption and diffusion. This study focuses on a Life Cycle Sustainability Assessment (LCSA) of an innovative process for the sorting and chemical recycling of multilayer plastic packaging waste from post-consumer sources to obtain new packaging for the food industry. The analysis indicated that the packaging made of rPET obtained through depolymerization is environmentally and economically competitive compared to the virgin PET. Packaging made of rPET and rLDPE obtained through delamination usually performed worse (or comparable) than the virgin counterparts. The social impact assessment indicated some areas of concern (e.g., workers’ health and safety risks due to exposure to hazardous substances), as well as potential opportunities (e.g., improved local employment). This paper is the first to present a synergetic approach to the sustainability assessment of chemical recycling technologies to obtain new high-performance packaging solutions. It provides useful insights to academics, managers, and decision makers in the plastic recycling sector whether (and under what conditions) the chemical recycling of multilayer plastic waste is feasible from the environmental, economic, and social perspectives. Despite associated uncertainties, the results are promising as an attractive option for further research, optimization, and upscaling.

Sustainability Impact Evaluation of the Recycling of End-of-Life Crystalline Silicon Solar Photovoltaic Panel Waste in South Korea

The end-of-life (EoL) management of solar panel waste has emerged as an important issue related to first-generation solar panels in South Korea, which have already entered their retirement stage. In this study, the sustainability impacts of three scenarios for recycling EoL solar panels, namely mechanical recycling (MR), chemical recycling (CR), and thermal recycling (TR), were investigated, and their environmental and economic benefits were evaluated using the life cycle sustainability assessment (LCSA) method, with landfilling as the reference scenario. The results obtained showed a high global warming potential (GWP) as well as acidification for MR owing to the additional burden of transportation and industrial processes associated with MR. For CR, the use of chemicals and subsequent landfilling resulted in approximately 4.7 times higher terrestrial eco-toxicity than was observed for the landfilling scenario. Further, the GWP of TR was approximately 1.5 times higher than that of CR owing to its high energy consumption. However, its environmental burden was generally lower than that of MR and CR. The results of this study, which capture the current situation of EoL PV panels in South Korea, can be employed to facilitate the establishment of regulations that ensure sustainable management in this regard.

A Systematic Review of BIM-Based Life Cycle Sustainability Assessment for Buildings

The construction industry has enormous impacts on the three dimensions of sustainability: environmental, economic, and social. To mitigate these impacts, several researchers have explored a variety of methods that link Building Information Modeling (BIM) with methodologies for a holistic evaluation of sustainability, such as Life Cycle Sustainability Assessment (LCSA). However, the complete integration of BIM-LCSA still remains unresolved, with a series of challenges that must be overcome. Consequently, the aim of this article is to identify the advances and challenges of BIM-LCSA integration focused on buildings through a literature review of the existing solutions presented by researchers worldwide. The PRISMA 2020 protocol is used. A total of 135 articles published between 2010–2023 are reviewed for bibliometric analysis. Furthermore, an exhaustive analysis of the case studies is carried out, by taking into account the structure proposed by ISO 14040. The authors identify a gap in the literature mainly regarding the full integration of the three dimensions with BIM that facilitates a simultaneous on-the-air assessment, in addition to the lack of a standardized LCSA method of calculation.

Enhancing environmental, social, and governance, performance and reporting through integration of life cycle sustainability assessment framework

AbstractWe introduce an innovative framework integrating Life Cycle Sustainability Assessment (LCSA) impact categories with Environmental, Social, and Governance (ESG) factors, offering a unified approach for ESG assessment and reporting. It covers sustainable development's key aspects, enabling a detailed evaluation of environmental, economic, and social performance across product and system life cycles, in line with the Sustainable Development Goals (SDGs). Incorporating the UN's 10 principles, the framework fosters a synergy to improve ESG reporting, adaptable across industries. To demonstrate its practicality, a theoretical application in Canada's oil and gas sector highlights how this framework can provide actionable insights for SDG‐aligned performance improvements. This example illustrates how the framework can identify and address sustainability issues, thereby improving ESG performance. Beyond its theoretical contributions, the framework serves as a valuable tool for practitioners and investors, promoting informed and comprehensive ESG reporting. Ultimately, it aims to enhance organizations' contributions towards achieving the SDGs and advancing global sustainability.

Improving the decision-making for sustainable demolition waste management by combining a BIM-based life cycle sustainability assessment framework and hybrid MCDA approach.

Increasing efforts have been devoted to promoting sustainable demolition waste management (DWM) from a life cycle-thinking perspective. To this end, facilitating sustainability-oriented decision-making for DWM planning requires a sustainability assessment framework for assessing multifaceted criteria. This study develops a building information modelling (BIM)-based DWM sustainability assessment approach to facilitate the life cycle assessment (LCA) and decision-making by coupling the enriched Industry Foundation Classes model with hybrid multi-criteria decision-aiding (MCDA) methods using Dynamo visual scripting. To streamline the data-intensive LCA process, this study enriched the BIM properties and accommodated them into the LCA data template to enhance data interoperability, thus achieving seamless data transfer. Moreover, hybrid MCDA methods are integrated into the decision-making workflow for DWM scenario ranking. A pilot study is employed to verify the applicability of the decision-aiding framework. The results unveil that the sustainability score ascended with the recycling rate. The optimal DWM alternative with the highest recycling rate yields the highest sustainability score at 91.63. Conversely, a DWM alternative reflecting the 'status quo' in China's recycling industry has the lowest score at 8.37, significantly lower than the baseline scenario with a 50% recycling rate. It is worth noting that the 'growth curve' of the sustainability score continuously flattens as the target recycling rate escalates. The increment in recycling rate from the 'Australian standard' scenario to the optimal scenario is 18.4%, whereas the sustainability score merely increases by 2.3%, signalling that the former scenario arrived at an optimum point for maximising the cost-efficiency of DWM under the predefined framework and contexts.

Life cycle sustainability assessment of microbial oil from organic waste

Microbial oils (MOs) are lipids produced by oleaginous microorganisms, which constitute an alternative to vegetable and fossil-derived oils. They can be produced from organic waste by coupling acidogenic fermentation (AF) with oleaginous fermentation (OF). This study addresses a life cycle sustainability assessment (LCSA) of MO produced from the organic fraction of municipal solid waste. First, a system was modelled using simulation tools. This model combines AF for the production of volatile fatty acids from organic waste, OF for the production of lipid-rich yeasts, and MO extraction. LCSA results indicate the need for improvements in the disruption of yeasts and the overall efficiency of the system. Particularly, slightly acidified thermolysis turned out to involve excessively high steam requirements. An enhanced sustainability performance could be achieved by exploring alternative disruption methods or alternative sources of energy for the production of steam such as biogas from the valorisation of the sludges produced in the system.

Supporting sustainability assessment of building element materials using a BIM-plug-in for multi-criteria decision-making

The environmental crisis requires the immediate implementation of accurate and robust sustainable solutions throughout the building life cycle. Life Cycle Sustainability Assessment (LCSA) is a scientifically recognised method that integrates the triple dimensions of the life cycle approach, and thereby enabling the evaluation of the performance of mitigation strategies implemented in building projects. However, implementing the LCSA in buildings is limited by the weighting of environmental, economic, and social dimensions to select the best option regarding the numerous materials available. In order to fill this knowledge gap, the paper aims to present the developed Smart BIM3LCA tool, which supports multi-dimensional assessment during the project´s early design steps. Automatic integration of the LCSA, a multi-criteria decision-making tool such as TOPSIS, and building information modelling (BIM), was developed to support the selection of building materials. The BIM plug-in was then validated through its application to a multi-family residential building to select the most sustainable materials during the project´s early design stage.

Sustainability assessment of products of the tropical tree moringa in Ghana with a focus on small-scale producers

With their numerous products and uses, multifunctional crops offer an attractive means for improving smallholder farmer livelihoods. This study applies a Life Cycle Sustainability Assessment (LCSA) to Moringa oleifera (moringa), a multifunctional crop with diverse applications in nutrition, cosmetics, and water treatment. The LCSA includes an Environmental Life Cycle Assessment (ELCA), Social Life Cycle Assessment (SLCA), and Life Cycle Costing (LCC). Surveys were conducted with 58 smallholder farmers and five moringa processors in Ghana. The ReCiPe 2016 Midpoint method was used for the ELCA. The 10-year Net Present Value (NPV) and Payback Period (PBP) were calculated for farmers and processors in the LCC. The SLCA focused on the Worker stakeholder category, particularly smallholder farmer impacts, including indicators for Next Generation Farming, Inclusiveness, Access to Services, Food Security, and Livelihood. A composite sustainability score was calculated from the ELCA, SLCA, and LCC results using the Characteristic Objects Method (COMET), a multi-criteria decision analysis method resistant to rank-reversal. The study compared five supply chains: leaf-only, leaf-and-seed, leaf-and-seed with seedcake reuse, seed-only, and seed-only with seedcake reuse. Environmental hotspots were identified in leaf and seed collection. Economically, leaf-only cultivation provided the highest 10-year NPV for farmers, while seed-only with seedcake reuse yielded the highest NPV for processors. The leaf-only supply chain had the best PBP for both farmers and processors. Socially, leaf-only cultivators outperformed reference points across all indicators, making it the most socially sustainable supply chain. Our findings highlight that improving market access, organizing seed cultivators into farmer-based groups, and optimizing farm gate product collection can enhance the sustainability of moringa supply chains, offering a model for other multifunctional crops in rural development. This study is the first to integrate LCSA with COMET, a promising approach that could be adopted in other sustainability assessment case studies.

Life cycle sustainability assessments of critical civil infrastructure systems: additional guidance for future research and practical application

ABSTRACT Sustainable development of critical civil infrastructure systems should include economic, environmental, and social considerations, as well as considerations that are of high value to stakeholders and decision-makers. Life cycle economic and environmental impacts of critical civil infrastructure systems are commonly quantified by well-established methodologies such as life cycle assessment and life cycle costing. However, social and other related impacts of critical civil infrastructure systems can be difficult to quantify and are therefore less commonly and thoroughly addressed. A mini-literature review was conducted to explore how sustainability is currently evaluated for critical civil infrastructure systems. The review found that, while there are life cycle assessment frameworks available, there is vague guidance available for addressing factors that are not directly related to environmental, economic, or social (i.e., difficult to quantify) impacts. In response, the authors build upon currently available methodologies by discussing a supplemental approach for collecting additional data for critical civil infrastructure systems, which includes the use of stakeholder discussions and semistructured interviews. Including a range of factors early on in life cycle sustainability assessments of critical civil infrastructure can improve study robustness and allow for further integration of decision-making factors in life cycle sustainability assessments.

Social life cycle sustainability assessment of dried tomato products based on material and process selection through multi-criteria decision making.

Tomatoes are a significant product of the Mediterranean region and a crucial component of the Mediterranean diet. The formulation of dried tomato products enriched with proteins and bioactive compounds could be a strategic approach to promote adherence to the Mediterranean diet. Six different novel tomato products were analyzed using different protein enrichment sources (pea proteins and leaf proteins) and drying technologies (hot-air dryer, microwave vacuum dryer, and conventional dryer). The novelty of this approach lies in combining product-specific criteria with global societal factors across their life cycles. Using 21 criteria and an analytic hierarchy process (AHP) survey of experts, the social sustainability score for each product was determined through a multi-criteria assessment. The tomato product's life cycles have minimal regional impacts on unemployment, access to drinking water, sanitation, or excessive working hours. However, they affect discrimination, migrant labor, children's education, and access to hospital beds significantly. The study identified nutritional quality as the top criterion, with the most sustainable design being a tomato bar enriched with pea protein and processed using microwave vacuum drying. The study revealed that integrating sensory and nutrient compounds into social sustainability assessments improves food sustainability and provides a practical roadmap for social life cycle assessments of food products. It emphasized the importance of considering global social issues when reformulating Mediterranean products to ensure long-term adherence to the Mediterranean diet. Incorporating social factors into sustainability scores can also enhance the effectiveness of product information for conscious customers. © 2024 The Author(s).

A systematic literature review of life cycle sustainability assessment of mass timber in the construction industry toward circular economy

AbstractLife cycle analysis has been used to evaluate the environmental impacts and economic costs of a range of engineered timber structural materials as well as other materials such as steel and concrete over the last two decades. This study presents a bibliometric analysis and systematic critical review by investigating the life cycle sustainability assessment (LCSA) of engineered timber products. LCSA is comprised of three main pillars namely, environment, cost, and social impact. The study compares alternative engineering wood products used in building structures such as columns, beams and wall surfaces. The geographical distribution, main sources of research, co-occurrence of keywords were analyzed for 93 peer-reviewed articles and conferences. The United States was the most productive country, contributing almost 23 documents. Australia was next with 12 publications. Most studies compared the LCA and LCC of alternative Mass timber products and concrete or steel. Most studies evaluated cross laminated timber (62%), followed by glued laminated timber (17%), and laminated veneer lumber (9%). A comparison of the economic and environmental aspects indicated that the social aspect are less considered. The review showed that the global warming potential of manufactring1 M3 of cross laminated timber is about 155.6–158.6 kg CO2eq. The majority of the publications reviewed focused on LCA whilst others focussed on the LCC of Mass timber. No research on social life cycle assessment has been conducted as yet. A framework is suggested for future research to identify the best alternative for engineering wood.
