However, many barriers exist to adoption, and current perceptions of and willingness to pay for circularity have yet to be quantified. This study seeks to understand the various perceptions of circularity in the construction industry, characterize uncertainties and risks, and identify economic incentives and opportunities that could accelerate circular adoption via an industry survey of three stakeholder groups. 58 stakeholders filled out part of the survey, and 42 stakeholders completed the majority of questions. Real estate developers are willing to pay an average premium of 10% for construction costs if there’s a minimum embodied carbon reduction of 53%. Design and construction professionals and material suppliers were also surveyed. Reasons for adopting circular practices were primarily driven by client, design team, and net zero goals. The results of this survey begin to characterize the economic landscape of what is needed for a circular transition in the built environment.","PeriodicalId":74322,"journal":{"name":"npj urban sustainability","volume":" ","pages":"1-10"},"PeriodicalIF":9.1,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s42949-024-00182-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142519172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although polycentric waste governance (PWG) has been introduced, characterizing the PWG remains challenging. This paper employs game theory to illustrate polycentricity by investigating the equilibrium state from the stakeholders’ perspective. Shanghai, Tokyo, and Hong Kong are selected as target cities for comparative analysis. The findings reveal the heterogeneous characteristics in three megacities’ PWG—the collaboration by principal stakeholders (formal recyclers, informal recyclers, households) in Shanghai, the exclusion of informal recyclers in Tokyo, and the limited contribution provided by the formal recyclers in Hong Kong. The divergent PWG characteristics can be attributed to variations in governance patterns, socioeconomic factors, and policy formulation. Regarding urban sustainability, Tokyo and Shanghai’s PWG contribute to the circular economy’s expansion, while Hong Kong’ potential, in this regard, is undervalued. Despite Tokyo’s improved social recognition to practitioners, this PWG mode, primarily driven by formal recyclers and households, presents limited inclusion of low-income groups. Additionally, it is crucial for the authorities in Shanghai and Hong Kong to acknowledge the potential pollution of informal recyclers’ non-environmental behavior. This paper offers a valuable model for characterizing and analyzing PWG across different cities, facilitating knowledge aggregation and the implementation of PWG practice.","PeriodicalId":74322,"journal":{"name":"npj urban sustainability","volume":" ","pages":"1-13"},"PeriodicalIF":9.1,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s42949-024-00179-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141968454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the various environmental impacts of urbanisation have been studied individually, integrated approaches are rare. This study introduces a spatially explicit model to assess urbanization’s effects on ecosystem services (green infrastructure availability, cooling, stormwater retention) and the environmental impact of building construction (material demand, greenhouse gas emissions, land use). Applied to the Netherlands from 2018 to 2050, our results show that integrating green infrastructure development with building construction could increase green areas by up to 5% and stabilize or increase ecosystem service provisioning. Dense building construction with green infrastructure development is generally more beneficial across the Netherlands, reducing resource use and enhancing ecosystem services. Conversely, sparse construction with green infrastructure is more advantageous for newly built areas. These findings offer insights into the environmental consequences of urbanization, guiding sustainable urban planning practices.","PeriodicalId":74322,"journal":{"name":"npj urban sustainability","volume":" ","pages":"1-12"},"PeriodicalIF":9.1,"publicationDate":"2024-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s42949-024-00178-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141968524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Access to urban green spaces such as parks and gardens supports resilience and well-being. Here, we studied how the pandemic influenced the attitudes towards and outcomes of urban box gardening in the city of Turku in Finland. We analyzed this small-scale social-ecological system before and during the pandemic in 2019, 2020, and 2021. We find that box gardening’s importance increased for many gardeners due to the pandemic, supporting that box gardening can enhance resilience. We find that gardeners remain motivated to cultivate but contrary to expectations, they report receiving fewer benefits, suggesting the pandemic’s negative influence on well-being extends to urban gardening. Our findings highlight the manifold and long-term influence of disturbances. The long-term changes in attitudes and outcomes suggest that the pandemic’s influence on urban gardening might be even transformative.","PeriodicalId":74322,"journal":{"name":"npj urban sustainability","volume":" ","pages":"1-10"},"PeriodicalIF":9.1,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s42949-024-00174-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141968525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the environmental impacts of a rapidly expanding online food delivery industry and its potential to mitigate environmental burdens remained unexplored in China. Our research found that Chinese cities generated 1.67 MtCO2-equivalent (CO2e) from 13.07 billion times of deliveries in 2019, including transport and packaging. The transportation-related GHG emissions were 745 KtCO2e in 2019, with an average of 0.057 kg CO2e per order and an average of 0.011 kg CO2e per capita. These emissions have surged from 0.31 MtCO2e in 2014 to 2.74 MtCO2e in 2021. We predict that this figure will increase further to 5.94 MtCO2e by 2035. However, with a range of policies such as replacing motorcycles with electric bikes and optimizing traffic routes, it is possible to mitigate such GHG emissions by 4.39–10.97 MtCO2e between 2023 and 2035. These findings highlight the need for further research into the environmental impact of online food delivery and the potential for mitigating it.","PeriodicalId":74322,"journal":{"name":"npj urban sustainability","volume":" ","pages":"1-13"},"PeriodicalIF":9.1,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s42949-024-00175-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141968526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
