Among these, perovskite/silicon (PSK/Si) tandem technology has garnered significant attention. However, existing Life Cycle Assessment studies on PSK/Si tandems exhibit significant uncertainty, complicating comparisons of environmental performance across different technologies. This study offers a comparative analysis of the environmental impacts of different PSK/Si tandem modules and silicon heterojunction (SHJ) modules, explicitly incorporating multiple sources of uncertainty to ensure a more comprehensive and reliable comparison. Uncertainty sources include uncertainty in 21 variable parameters (e.g., lifetime and power conversion efficiency), differences between two-terminal and four-terminal tandem architectures, and alternative degradation scenarios of tandem modules. Propagating these uncertainties through parameterised models allows for a direct comparison of the resulting distributions of environmental impacts for tandem and SHJ modules. For example, in the case of modules manufactured in France, PSK/Si tandems show climate change impacts ranging from 5.5 to 8.7 g CO₂ eq/kWh, whereas SHJ modules range from 6.3 to 9.4 g CO₂ eq/kWh. To streamline comparisons, global sensitivity analysis identifies the key parameters contributing most significantly to output uncertainty. These insights inform the development of simplified arithmetic models that require only a limited set of key inputs. Such models enable rapid, accurate estimation of environmental impacts for both PSK/Si tandem and SHJ modules, facilitating efficient and reliable comparisons. Overall, this work enhances understanding of the environmental performance of PSK/Si tandem and SHJ modules and supports strategies to improve their sustainability, thereby guiding strategic decision-making in the renewable energy sector.</div></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"20 ","pages":"Article 100388"},"PeriodicalIF":4.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145938435","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}

Initial phases of the implementation of such kinds of projects include feasibility studies, conceptual design, and design development and permitting, with environmental considerations being crucial. This paper proposes detailed and simplified Life Cycle Assessment (LCA) models to support project developers. The study focuses on three specific environmental impact categories: abiotic depletion potential of fossil fuels (ADP:FF) and minerals/metals (ADP:MM) and climate change. These categories were selected to ease explanation and their direct relationship with system inputs and outputs facilitate the improvement of overall performance. Detailed models help project developers with the support of LCA experts identify processes contributing the most to environmental impacts, facilitating improvements during conceptual design, and design development and permitting. Simplified models can be directly and easily used by project developers to analyze environmental compliance of project options during feasibility studies. A detailed model uses parameters to describe system inputs and outputs, which is then simplified through Global Sensitivity Analysis to reduce the number of these parameters. In this paper, the proposed approach is applied to a microalgae-based biogas production system. Our detailed model uses 39 parameters, identifying materials and energy flows contributing to environmental impacts. Main contributors are enzymes production for pretreatment and CO₂ production for cultivation. The simplified models generated in this paper ease early estimation of environmental performance thanks to the use of less than 19 parameters instead of 39, reducing data collection time.</div></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"20 ","pages":"Article 100384"},"PeriodicalIF":4.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145938440","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}

Moreover, it considers contextual volatility as a contextual factor that moderates the relationship between green dynamic capabilities and environmental performance. Empirical evidence was obtained via survey data collected from 103 greenhouse managers in Iran. Findings from structural equation modeling demonstrate a direct positive link between CSR and environmental performance. In addition, CSR promotes the development of green dynamic capabilities, which subsequently foster improved environmental outcomes. Nevertheless, when contextual volatility is high, the beneficial effect of green dynamic capabilities on environmental performance diminishes. These results underscore CSR's strategic value for small firms in resource-limited contexts. For policymakers, the study suggests providing incentives to encourage CSR practices, while managers are advised to strengthen green dynamic capabilities to maintain environmental progress in volatile markets.</div></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"20 ","pages":"Article 100396"},"PeriodicalIF":4.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147395690","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 address inconsistencies, a hybrid labeling approach was introduced for classifying data types and economic levels. Results show that CE indicators collectively span all sustainability domains but remain unevenly distributed, with quantitative and meso-level indicators prevailing and micro-level ones underrepresented. Three key insights emerge: (1) large datasets reduce bias in CE assessment; (2) multi-level classification enables clearer interpretation; and (3) binary labeling oversimplifies contextual complexity.
