However, its widespread adoption requires knowledge of its implications at the different levels of the urban water cycle. This paper aims to provide a holistic overview and global understanding of the opportunities, challenges and implications associated with the widespread adoption of water conservation measures on the urban water cycle. A systematic search was conducted to identify water conservation case studies within the municipal sector. The analysis of studies' results highlighted that water conservation can significantly reduce buildings' water use while also providing energy savings in both buildings and water utilities. Water conservation measures were found to be economically feasible in most cases, with relatively short payback periods, although conclusions were more nuanced when adopting alternative water sources. This suggests that water conservation measures may be a better option than supply-side solutions to maintain water supply in cities. However, their performance may be undermined by design problems or user behaviour. Therefore, education and communication are key drivers for their widespread adoption. Lower water demand resulting from the implementation of conservation measures may reduce the need for water systems upgrades, delaying major investments, but this may also adversely impact these systems, causing water quality issues in distribution networks, degrading the hydraulic performances of sewers, and altering wastewater treatment efficiencies. The widespread deployment of water conservation measures requires technical, financial, social, and political considerations. Further research is still required to better understand its implications for water systems, assess its impact on water and energy use, and support decision-makers in developing water conservation programmes.</p></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"50 ","pages":"Pages 571-586"},"PeriodicalIF":10.9,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2352550924002525/pdfft?md5=1aeb0132ca9a6b93c351fda50eb5c93e&pid=1-s2.0-S2352550924002525-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142149149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To promote circular economy initiatives, this study aims to provide insight into the variables and the conditions that play a key role in the expression of environmental impacts and find the better path for a circular economy of solar panels, which requires analyzing impacts on multiple indicators as a result of various factors and their cross-interactions. To achieve this goal, we constructed a resource circulation simulator that considers factors related to the business environment as well as physical factors. The simulation model was then applied to the largest administrative region in Japan, and the parameter space was explored by combining Regional Sensitivity Analysis, a global sensitivity analysis method, and Random Forest to consider the interactions among these variables. As a result of 30,000 Monte Carlo simulations performed on 26 input variables, it was found that the key parameters in final disposal and resource consumption potential differ between the two purposes; avoiding catastrophic loads and achieving ambitious reductions. In contrast, for greenhouse gas emissions, it is important to maintain or increase the efficiency of photovoltaic panel power generation for both purposes. Additionally, in the case where the key variables were optimized in terms of final disposal/resource consumption potential, it will effectively reduce the two impacts to 0.7 % and 12.6 %, respectively, with a minimal negative impact on greenhouse gas emissions. In contrast, in the case when optimized in terms of greenhouse gas emissions, it has only a small impact on greenhouse gas emissions and large negative impacts on final disposal and resource consumption potential.

Design researchers, at the same time, develop and propose a plethora of new and improved design methods that can support the manufacturing industry in such transformation. It is, despite this, well-documented in literature that the industrial adoption of such proposed design methods is challenging. Previous research in the design domain has mainly studied this issue from a process and methodological perspective, whereas previous research in the management domain instead has focused on organizational, and human-behavioral aspects. This poses a research gap for more interdisciplinary research that studies the adoption of design methods from all three perspectives (i.e., process and methodology, organization, and human behavior). Six parallel case studies were carried out with three different product development and manufacturing organizations to collect qualitative empirical data. Glaserian grounded theory was used to analyze the collected data. This resulted in a descriptive framework that captures 53 interdisciplinary factors influencing the adoption of sustainable design practices using new and improved design methods. The descriptive framework is compared to interdisciplinary literature to further clarify and explain the findings, highlighting both practical and theoretical implications.

However, relatively little research has been undertaken to predict future interregional carbon inequality in China from an HWB equity perspective based on scenarios combining shared socioeconomic pathways (SSPs) and carbon reduction policies. The biproportional scaling method named after economist Richard Stone (RAS) was used to predict China's 2020 to 2050 multiregional input–output (MRIO) tables. Then, these MRIO tables were used to simulate future net carbon emissions (NCEs) and net human well-being (NWB) transfers under the SSP1–1.5 °C, SSP1-NEU, SSP2-2 °C and SSP5-BAU scenarios. China's interregional carbon inequality was predicted under different scenarios to clarify the ideal path for mitigating carbon inequality. In the SSP1–1.5 °C, SSP1-NEU, SSP2-2 °C and SSP5-BAU scenarios, the total carbon emissions (CEs) clearly decrease, whereas the total HWB clearly increases. Transfers of NCEs between regions increases, and transfers of NWB between regions decreases in each of the four scenarios. According to the mean regional environmental inequality (REI) value, China's interregional carbon inequality is relatively low under the SSP1–1.5 °C and SSP1-NEU scenarios and relatively high under the SSP2–2 °C and SSP5-BAU scenarios. Mitigating interregional carbon inequality is a long-term and arduous task that requires commitments from governments, businesses and society. These findings clarify the optimal path for China to reduce carbon inequality in the future and provide a theoretical basis for government agencies to rationally adjust the current development model.

This study addresses this gap by integrating emerging technologies omitted in IAMs into future markets, providing a more robust foundation for pLCAs. Diesel, widely used in transportation, heating, and power systems, has established itself as an integral part of the world's infrastructure. Hence, to illustrate our approach, here we analyze the future environmental impacts of heavy-duty trucks fueled with synthetic Fischer-Tropsch e-diesel, incorporating our technology in the diesel market of the background system, through an integrated LCA approach. The standard non-integrated LCA would analyze these technologies in the foreground, assuming that the background is given. In contrast, our integrated LCA, which is particularly suited for cases where technologies in the foreground are deployed at scale, makes both systems consistent with each other. Our findings reveal mismatches in climate impacts depending on the climate pathway and technology of up to 35 % between the integrated and non-integrated approaches, which increase over time, particularly from 2020 to 2050, and are more pronounced when assessing highly carbon-negative or carbon-positive technologies. Overall, we stress the importance of having consistent foreground and background systems for performing more meaningful and accurate LCAs.

A multi-objective optimization model is employed to identify optimal technical pathways that balance economic, environmental, and energy objectives.

In contrast, a multi-objective optimization solution prioritizing incineration and anaerobic digestion achieves environmental and energy benefits valued at 18.7 USD/t, with a modest increase in economic costs of 5.7 USD/t compared to the base year. The unconstrained optimal scenarios achieve net negative environmental costs and recover 2.0 × 10<sup>6</sup> MJ of energy.
