The focus is on the production organisation, and how production operations could contribute to strategic circularity change. Prior research has used the Green kaizen methodology to identify environmental aspects and circularity related to the input-output flow of resources at the production shop floor. However, this paper finds that a more comprehensive approach is required, involving all levels of the production organisation. First, the paper defines circular production principles for production operations, showing that these principles vary across different company levels. Operations and shop floor level principles tend to be closer to the production input-output system, whereas factory management level principles are more focused on information sharing and internal and external relations. The circular production principles followed a hierarchical organisational structure with a bottom-up drive, where the allocation of organisational resources increased as the level of the hierarchy increased. The study reveals parallels with Likert's management system, where green kaizen activities are suitable for the shop floor level, but business development requires authority exploitation. Secondly, the paper identifies four circularity impact factors that apply to all company levels. These factors enhance the practical utility and implementation of circularity aspects, making them applicable to all levels of the company. The framework for bottom-up escalation of circular production principles can be used as a roadmap or support for managing a circularity bottom-up transition work. The findings presented in this paper fill a knowledge gap regarding the organisational and managerial work required for circular production. Specifically, this paper addresses challenges related to circular production management, including the gap between strategic targets and operational-driven work. By proposing a comprehensive framework for operationalising circular production principles, this paper offers practical guidance for production companies seeking to transition to circular economy practices.</p></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"4 ","pages":"Article 100038"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50188793","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}

Ecological network analysis is conducted to identify the main sectors contributing to the direct and indirect carbon emissions in the four cities.

Future low-carbon fuels use in the maritime transport to curb GHG emissions can increase freight rates and affect trade, especially for commodities transported over long distances. This study performed a case study to evaluate lignocellulosic marine biofuels use in soybean trade routes from Brazil and U.S. to China, in terms of supply volumes, GHG emissions and potential increase on freight costs. This is the first attempt to assess biofuel use in a specific product trade. To this end, two scenarios and three technologies were developed for biofuels availability from 2020 to 2050. Findings reveal that Brazil benefits from higher biofuel supply and four Brazilian biofuel pathways meet total bunker fuel demand in 2050, while U.S. pathways supplied up to 24%. However, emission reduction come at significant cost increase with abatement costs reaching more than US$ 300/tCO₂e for some of the Brazilian and U.S. pathways. To reduce this cost gap, market instruments, such as carbon price of at least US$ 100/tCO₂e would be required. Nevertheless, fuel cost increase has not resulted in significant cost variation between Brazilian and U.S. vessel routes. Hence, Brazilian trade routes could keep lower freight costs than U.S. even with higher biofuel shares. This indicates that regions capable of supplying low-carbon fuels can become more competitive in their exports in a decarbonized maritime trade.</p></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"4 ","pages":"Article 100028"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50189394","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}

The urban metabolism field of research is one of the fields that focuses on understanding and measuring this increase at the city level. Many studies have been carried out to calculate the material consumption at the domestic scale. But it is also important to include the non-domestic scale to account for the amount of materials extracted outside the city that were needed along the supply chains to produce the final products consumed in the city. This is referred as the material footprint, which provides a consumption-based indicator of resource use. The objective of this study was to develop a method to measure the material footprint of the cities of Nantes-Saint-Nazaire (France) and Gothenburg (Sweden), both port cities and pioneers in the implementation of urban policies targeting a circular economy. The methodology combines urban material flow analysis with multi-regional input-output database to extend the urban metabolism beyond the administrative boundaries of cities. We then calculated the absolute and per capita material footprints of the two cities and its material disaggregation. We compared these results with domestic material consumption. Further analysis of the urban material footprint was performed by spatializing the flows in the global economy to understand the extent of consumption due to cities. The results show that on average the material footprint is 2.4 times larger than the domestic material consumption in Gothenburg and 1.9 times larger in Nantes-Saint-Nazaire. A decoupling between material footprint and domestic material consumption can be observed, as the material footprints grew much faster than the domestic material consumption. Regarding the material disaggregation, the most significant category is non-metallic minerals, which weighs more than 50% on average of the total material footprint balance sheet and also increased the most. In conclusion, future work should thus better integrate material footprint, as there is a need to better understand the externalization of urban metabolism and to identify what aspects urban circular economy policies should focus on.</p></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"4 ","pages":"Article 100029"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50189440","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}

Current research confirms that sustainable investments can have a positive influence on financial performance, but how that effect materializes is still debated. This study argues that the ambiguity concerning this positive impact is caused by a lack of integration of sustainability in organizations. This lack of integration causes the sustainability efforts to harm financial performance of the pension funds. Nevertheless, research shows that, if sustainability is integrated in the core logic of the organization, sustainability efforts do not yield lower returns. We assess the current level of sustainability integration in the Dutch pension fund sector using a multiple case study approach. Next, this study formulates the challenges related to sustainability integration in the sector, after which solutions to the specific problems are presented. Given the lack of integration, the barriers for increasing sustainability integration can be viewed as a Catch-22. First, a perceived separation is observed between the societal pressure to invest sustainably and constituents’ pressure to realize financial value. Second, pension funds are ill equipped for the complexity in sustainable investing and use a third party as investment manager, creating a dispersion of knowledge of sustainable investments and the responsibility to do so. To be able to solve the Catch-22 dilemma, greater collaboration, standardization and a sustainability vision are needed, resulting in a positive impact on sustainability and positive effects on financial return.</p></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"4 ","pages":"Article 100030"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50189442","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}

Third, fossil fuel production undermines cleaner energy development as 1% growth in nonrenewable energy causes a 0.20% decline in renewable energy generation.
