Life Cycle Assessment (LCA) aims to analyze possible impact upon manufacturing process and availability of products, and also study the environmental considerations and potential influence during entire life cycle ranging from procurement, production and utilization to treatment (namely, from cradle to tomb). Based on high‐density polyethylene (HDPE) pipe manufacturing of company A, this case study would involve evaluation of environmental influence during the production process. When the manufacturing process has been improved during “production process” and “forming cooling” stage, it is found that capital input on “electric power” and “water supply” could be reduced, thus helping to sharpen the competitive power of company A, and also ensure sustainable economic and industrial development in accordance with national policies on environmental protection.

Sustainability investors are in need of updated standards, indexes and in general better tools and instruments to facilitate company information on its impacts on people, planet and profit. Such instruments to reveal reliable, independent metrics and indicators to evaluate companies’ performances on sustainability exist, however, in research fields that previously have not been used extensively, for instance, life cycle assessments (LCAs). ISO 14001:2015 has implemented life cycle perspective, however, without being explicitly clear on which methodology is preferred. This paper aims to investigate LCA as to improve companies’ transparency towards sustainability investors through a literature review on sustainable investment evaluation.

The literature review is conducted through the search engine Google Scholar, which to date hosts the most comprehensive academic database across other databases such as Scopus, ISI Web of Knowledge, Science Direct, etc. Search words such as “Sustainable finance”, “Sustainable Investments”, “Performance metrics”, “Life cycle assessment”, “LCA”, “Environmental Management Systems”, “EMS” and “Environmental Profit and Loss Account” were used. Special journals that publish research on LCA such as International Journal of Life Cycle Assessment, Journal of Cleaner Production and Journal of Industrial Ecology were also investigated in-depth.

The combination of using LCA in, for instance, environmental profit and loss accounts studied in this paper shows a comprehensive and reliable tool for sustainability investors, as well as for social responsibility standards such as ISO 14001, ISO 26000, UN Global Compact, GIIN, IRIS and GRI to incorporate. With a LCA-based hybrid input-output account, both upstream and downstream’s impact on the environment and society can be assessed by companies to attract more funding from sustainability investors such as shareholders, governments and intergovernmental bodies.

The literature review is based on publicly disclosed academic papers as well as five displayed company Environmental Profit and Loss accounts from the Kering Group, PUMA, Stella McCartney company, Novo Nordisk and Arla Group. Other company experiences with integration of LCA as a reporting tool have not been found, yet it is not to conclude that these five companies are the only ones to work extensively with LCA.

The paper may contribute to the clarification of LCA-thinking and perspective implementation in both ISO 14001 and ISO 26000, as well as in other social responsibility standards such as the UN Global Compact, the Global Impact Investing Networks, IRIS performance metrics, the Global Reporting Initiative and others.

The paper is one of the first that evaluates LCA and environmental profit and loss accounts for sustainability investors, as well as for consideration of implementation in social responsibility standards such as the ISO 14001 and ISO 26000, as well as in other social responsibility standards such as the UN Global Compact, the Global Impact Investing Networks, IRIS performance metrics and the Global Reporting Initiative.

Wastewater treatment plants (WWTPs) have long-time environmental impacts. The purpose of this paper is to assess the environmental footprint of two advanced wastewater treatment (WWT) technologies in a life cycle and sustainability perspective and identify the improvement alternatives.

In this study life cycle-based environmental assessment of two advanced WWT technologies (moving bed biofilm reactor (MBBR) and sequencing batch reactor (SBR)) has been carried out to compare different technological options. Life cycle impacts were computed using GaBi software employing the CML 2 (2010) methodology. Primary data were collected and analysed through surveys and on-site visits to WWTPs. The present study attempts to achieve significantly transparent results using life cycle assessment (LCA) in limited availability of data.

The results of both direct measurements in the studied wastewater systems and the LCA support the fact that advanced treatment has the best environmental performance. The results show that the operation phase contributes to nearly 99 per cent for the impacts of the plant. The study identified emissions associated with electricity production required to operate the WWTPs, chemical usage, emissions to water from treated effluent and heavy metal emissions from waste sludge applied to land are the major contributors for overall environmental impacts. SBR is found to be the best option for WWT as compared to MBBR in the urban context. In order to improve the overall environmental performance, the wastewater recovery, that is, reusable water should be improved. Further, sludge utilisation for energy recovery should be considered. The results of the study show that the avoided impacts of energy recovery can be even greater than direct impacts of greenhouse gas emissions from the wastewater system. Therefore, measures which combine reusing wastewater with energy generation should be preferred. The study highlights the major shortcoming, i.e., the lack of national life cycle inventories and databases in India limiting the wide application of LCA in the context of environmental decision making.

The results of this study express only the environmental impacts of the operation phase of WWT system and sludge management options. Therefore, it is recommended that further LCAs studies should be carried out to investigate construction and demolition phase and also there is need to reconsider the toxicological- and pathogen-related impact categories. The results obtained through this type of LCA studies can be used in the decision-making framework for selection of appropriate WWT technology by considering LCA results as one of the attributes.

The results of LCA modelling show that though the environmental impacts associated with advanced technologies are high, these technologies produce the good reusable quality of effluent. In areas where water is scarce, governments should promote reusing wastewater by providing additional treatment under safe conditions as much as possible with advanced WWT. The LCA model for WWT and management planning can be used for the environmental assessment of WWT technologies.

The current work provides a site-specific data on sustainable WWT and management. The study contributes to the development of the regional reference input data for LCA (inventory development) in the domain of wastewater management.

Some universities have a commitment to both academic education and sustainable development, and the sustainable development goals can support several sustainable actions that universities may take as principles and attitudes. From this perspective, the purpose of this study is to present environmentally sustainable practices at a federal university in Brazil and to analyze and discuss the potential environmental impacts associated with an environmentally sustainable practice implemented using life cycle assessment (LCA) and its benefits for the university’s decision-makers.

To accomplish that, the study combines a description of environmentally sustainable practices at the 13 campuses of the Universidade Tecnológica Federal do Paraná (UTFPR) in terms of education, water and electricity consumption, waste management and emissions. As a result of this analysis, one campus identified that a high volume of disposable plastic cups were being disposed of, for which the use of reusable plastic cups was introduced. In addition, an LCA study (ISO 14040:2006 and 14044:2006) quantified the benefits of the introduction of said reusable plastic cups.

The results show that the university is working on environmentally sustainable initiatives and policies to become greener. At the same time, using a systematic LCA made it possible to measure that replacing disposable plastic cups for reusable ones reduced waste generation but increased water consumption on the campus. Faced with this, a sensitization was carried out to reduce water consumption. Finally, the current study provides lessons on the environmental performance to universities interested in sustainable practices, fostering perspectives for a better world. The findings of this study encourage organizations to accomplish environmental actions toward greener universities. The study shows that institutions need to be reflective and analytical about how even “greening” measures have impacts, which can be mitigated if necessary.

The sustainable practical implications were reported, and an LCA was conducted to assess potential environmental impacts of reusable plastic cups. It was identified that raw material production is the phase that generates most environmental impacts during the life cycle of the product, along with the consumer use phase, due to the quantity of water used to wash the reusable cups. In addition, the practical contributions of this study are to provide insights to institutions that aim to use environmental actions, i.e. suggestions of sustainable paths toward a greener university.

This is one of the first studies to investigate and discuss sustainable practices at UTFPR/Brazil. The study assessed one of the practices using a scientific technique (LCA) to assess the impacts of reusable plastic cups distributed to the students of one of the 13 campuses. Although there are other studies on LCA in the literature, the value of this study lies in expanding what has already been experienced/found on the use of LCA to assess environmental practices in university campuses.

The purpose of this paper is to report on a life cycle assessment (LCA)-based ecodesign teaching practice via university-industry collaboration in an industrial engineering undergraduate course.

A new course was designed and taught in the Industrial Engineering undergraduate course of a Federal University in Brazil. The course comprised explanatory lectures and a practical project developed in a partnership between the university and an industry partner where students had to develop Ecodesign proposals based on LCA to improve the environmental profile of both solid and reticulated paint brushes. To that end, students used the LCA software tool Umberto NXT v.7.1.13 (educational version), where they modeled the life cycle of four plastic brushes and assessed it using the impact categories of climate change and resource consumption, and the Ecoinvent v.3.3 database. After course completion, students, professors and industry collaborators were asked to provide feedback on the project performance and expectations.

The course design used was welcomed by both students and the industry partner. Students found the novel approach intriguing and useful to their future careers. The results also exceeded the industry partner’s expectations, as students formulated valuable insights. Professors observed that learning was made easier, as content was put into practice and internalized more easily and solidly. The approach was found to be a win-win-win.

Students acquired a fair share of knowledge on sustainability issues and potential existing trade-offs, which is valuable to industrial practices. The industry noticed the valuable contributions that academia can provide. The university profited from providing students with a real case challenging traditional teaching methods.

To the best of the authors’ knowledge, this is one of the first case studies to show how LCA and ecodesign teaching practice can support sustainability learning in an industrial engineering undergraduate course.

The South African Construction Industry (SACI) in recent times has been characterized by a strong emphasis towards achieving sustainable building practices in infrastructural delivery. However, the lack of progress encountered in making gains in achieving sustainable practices has raised concerns over the effectiveness and understanding of the extent to which life cycle assessment (LCA) techniques may aid in meeting requirements of sustainable construction. Most efforts at LCA have been blighted with numerous barriers that have not been rigorously pursued and aggregated. Ironically, there is a lack of knowledge and understanding of the limitations and barriers to these methodologies, especially in the South African context. The purpose of this study is to delineate the cluster of barriers to the adoption of LCA methodologies in the SACI.

A questionnaire survey was carried out from a deductive research design elicit primary data based on the experience of purposively sampled stakeholders in LCA in the SACI on the extent they perceived the presence of well-established barriers in LCA adoption culled from the extensive literature review.

Through the use of factor analysis, three aggregated clusters of key barriers to LCA adoption in the SACI were identified, which were knowledge and enabling conditions constraints, cost and time constraints and technical constraints. The results confirm that indeed human and technical barriers have been notable in limiting gains in LCA adoption and achieving sustainable practices.

These findings are, thus, useful in overcoming challenges to LCA methodologies in achieving sustainable building practices in building and infrastructural delivery in SACI.

This study aims to share experiences of an easy to adapt service-learning approach in a graduate course on life cycle assessment (LCA). Specifically, it reports on how students helped the university’s cafeteria to assess meals by conducting an LCA for 25 meals and identifying environmental hotspots.

A descriptive case study of a graduate course at Ulm University is presented. The course included lectures and problem-based exercises, both theoretical and software assisted. A course evaluation was conducted during the course and one year after completion to poll improvement potentials, as well as its impacts on students’ everyday life.

It was found that although it was the first LCA for all students, the resulting LCA information of 25 different meals were homogeneous, comparable to the scientific literature and beneficial to the cafeteria’s sustainable development strategy. The concept of service-learning had a higher impact on students’ motivation than a good grade and active-learning is explicitly requested by students. The course design sensitized students to the real-life problems of LCA and made their consumption patterns more elaborate and ecological. Furthermore, this digitization of higher education could be carried out with only minor changes in the present COVID-19 pandemic situation.

As the subject of service-learning in natural sciences is still expandable, this study presents an easy to adapt case study on how to integrate such an approach into university curricula dominated by traditional learning. To the best of the authors’ knowledge, this case study presents the first published LCA university course explicitly describing and evaluating a service-learning approach. The topic touches the everyday lives of students, allows comparisons between different student groups, is easily scalable to different group sizes and credits, and supports learning both how to study in small groups and cooperation between groups to ensure comparability of LCA results.

In this paper, of exploratory character, the purpose of this paper is to propose the analysis of the life cycle for assessing the environmental, economic, and social impact in the activity of recovery, restoration, and valorization of Cultural Heritage.

The analysis protocol is applied to the case of recovery and restoration processes and then outlining the salient features of what may become a model of Cultural Heritage Life Cycle Management (CH-LCM).

The authors propose the approach of the life cycle, normally used to assess the impact of materials, processes or products, to the management of cultural heritage as an innovative methodology with great potential.

The methodology for this sector is highly innovative, especially in its interdisciplinary approach, through the use of different technical, historical, and economic skills which can provide the tools for the preparation of a management plan according to the logic of the life cycle.

Life cycle assessment (LCA) has considerably contributed to increasing the environmental friendliness of buildings in developed countries. However, it is hard to find evidence on the application of LCA for buildings in developing countries; particularly, Sri Lanka. There is a lack of research to compare the status of LCA of buildings in developed countries vs developing countries. In this context, the purpose of this study aims to examine the status of LCA implementation for buildings between developed countries and Sri Lanka, a developing country.

The exploratory research was adapted, and in-depth interviews were held with LCA professionals from Sri Lanka and developed countries, respectively.

Relatively less attention has been paid to the implementation of LCA for buildings in Sri Lanka compared to the developed countries due to the time and effort required to collect life cycle inventory data and limited stakeholder understanding of the LCA. Hence, this study proposed improvements, including the development of LCA databases containing region-specific data and conducting programmes to raise stakeholders' awareness to address the gaps in Sri Lanka.

The identified LCA implementation process for buildings could be used as a guide for first-time LCA users, and it equally makes a valued reference for experienced practitioners.

A limited number of the studies formulate a comparison between the LCA for building in developed countries and developing countries. This research attempts to address this knowledge gap.

The purpose of this study is to compare the life cycle environmental impacts of the University of Cincinnati College of Engineering and Applied Sciences' current printed annual report to a version distributed via the internet.

Life cycle environmental impacts of both versions of the report are modeled using the online environmental input‐output life cycle assessment (EIO‐LCA) tool. Most monetary model inputs were obtained from the University of Cincinnati and the others were estimated. Results are presented for greenhouse gas (GHG) emissions, energy use, water use, and human and ecosystem health impacts. Alternative scenarios reflecting different reader behaviors were evaluated.

The electronic report reduces economic costs and all categories of environmental impacts so long as the recipients do not print the report at home. Impacts of the printed report were higher than the electronic report due to impacts associated with paper production and disposal and to a lesser extent differences in the impacts of mail versus electronic distribution. The environmental preferability of the options is heavily influenced by the number of users who choose to print the electronic report at home; if more than 10 percent print at home, it offsets the benefits of the e‐report.

Using the EIO‐LCA tool limited the accuracy of the results by using average US data for a specific supply chain. It was limited by assumptions about reader behavior with the e‐report.

This case study demonstrates how a screening level life cycle assessment (LCA) might be used by a university administrator to make decisions supported by quantitative environmental information.

The screening level LCA‐based approach can provide grounding for environmental decision making within a reasonable time period and cost while maintaining sufficient accuracy for guiding purchasing or product decisions.
