Abstract The anticipated increase in urban population of 2.5 billion people by 2050 poses significant environmental challenges. While the various impacts 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 impact building construction (material demand, greenhouse gas emissions, land use). Applied Netherlands from 2018 2050, our results show that integrating green development with could areas up 5% stabilize or service provisioning. Dense is generally more beneficial across Netherlands, reducing resource use enhancing services. Conversely, sparse advantageous for newly built areas. These findings offer insights into consequences urbanization, guiding sustainable planning practices.

Scenario analysis of supply‐ and demand‐side solutions for circular economy and climate change mitigation in the global building sector

Journal of Industrial Ecology, Год журнала: 2024, Номер 28(6), С. 1699 - 1715

Опубликована: Окт. 8, 2024

Abstract Residential and non‐residential buildings are a major contributor to human well‐being. At the same time, cause 30% of final energy use, 18% greenhouse gas emissions (GHGE), about 65% material accumulation globally. With electrification higher efficiency buildings, material‐related gain relevance. The circular economy (CE) strategies, narrow, slow, close , together with wooden can reduce emissions. We provide comprehensive set building stock transformation scenarios for 10 world regions until 2060, using resource climate change model stock–flow–service nexus including full CE spectrum plus wood‐intensive buildings. 2020–2050 global cumulative new construction ranges from 150 280 billion m 2 residential 70‐120 Ambitious reduces primary demand 80 30 gigatons (Gt) cement 35 15 Gt steel.

Digital technology adoption in circular startups: An integrated framework

Business Strategy & Development, Год журнала: 2024, Номер 7(3)

Опубликована: Авг. 27, 2024

Abstract While the role of digital technologies (DTs) in facilitating entrepreneurship is well established, research on understanding DTs among circular start‐ups as part their overall strategy scarce. This vital from perspective emerging economies, such India. The study aims to identify and analyse factors influencing technology adoption using Technology‐Organisation‐Environment (TOE) framework Technology Acceptance Model (TAM) form a novel Circular Startup Digital Adoption (CSDA) framework. In addition integrating TOE TAM, utilises systematic literature review with subject‐matter‐expert (SME) consultation order determine CSDA To best authors' knowledge, this first studies behind by startups an economy perspective, offering theoretical, managerial policy implications.

Circular strategies for building sector decarbonization in China: A scenario analysis

Journal of Industrial Ecology, Год журнала: 2024, Номер 28(5), С. 1089 - 1102

Опубликована: Июль 11, 2024

Abstract The building sector in China is responsible for 40% of total energy‐related CO 2 emissions, driven by its large population, continuous economic growth, and construction boom. In addition to greenhouse gas (GHG) emissions from energy use, buildings drive significant activities production energy‐intensive materials, such as steel cement. While supply‐side strategies have been extensively explored, a demand‐side perspective that considers stock dynamics circularity improvements essential assess sustainable pathways the sector. Here, we explore set decarbonization scenarios considering range circular their interplay with different climate policies. include lifetime extension buildings, switch wood‐based construction, reduction per‐capita floorspace, combination all three strategies.

Optimising the Circular Economy for Construction and Demolition Waste Management in Europe: Best Practices, Innovations and Regulatory Avenues

Sustainability, Год журнала: 2025, Номер 17(8), С. 3586 - 3586

Опубликована: Апрель 16, 2025

This article explores the sustainable management of construction and demolition waste (CDW) as part a circular economy in Europe. It provides an overview current European practices, identifies main challenges associated with collecting, sorting recycling waste, highlights need to design buildings that encourage reuse materials. The study also draws on best practice from internationally recognised examples such Japan, Singapore, California, Netherlands China, which effectiveness combination strict regulations, economic incentives advanced technologies. These international cases provide valuable lessons can be adapted context improve situation fill gaps policy, innovation education. recommends targeted measures strengthen harmonising standards, promoting eco-design principles public procurement, investing research development (R&D) establishing green administrative practices. By adopting these strategies, Europe significantly CDW, fostering more resilient, integrated economy.
