Bud-Mi
Mapping construction material stocks is essential for understanding socioeconomic metabolism and informing the circular economy. However, spatial material stock studies often produce coarse results owing to challenges in material intensity development. This paper introduces BUD-MI (Bottom-Up Data: Material Intensity), a material intensity data collection template designed with three core objectives: streamlining the data collection process during…
Assessing resource efficiency in Vietnam
This study aims to comprehensively evaluate Vietnam's resource efficiency to support sustainable development by developing and applying an integrated resource efficiency assessment framework (IREAF). Since the 1990s, Vietnam's economy has undergone rapid development, resulting in unprecedented growth in resource consumption and environmental pressures. To address this, we propose a multidimensional framework that combines economy‐wide material fl…
Shedding light on the shadows
Life cycle assessment (LCA) hinges on the transparency and reliability of inventory data. However, the transparency of background life cycle inventory (LCI) data sources remains unexamined. This research assesses data transparency in mainstream LCI databases using a two‐step examination system based on source findability and accessibility. Six major databases (ecoinvent, GaBi, U.S. Life Cycle Inventory Database, European Life Cycle Database, Inve…

Global material flows and resource productivity
Accurate assessments of global primary material extraction, trade of primary materials and products, material use, waste, and emissions support the development of policies that facilitate the decoupling of economic activity, natural resource use, and related environmental impacts. Here, we quantify all crucial aspects of global and country‐by‐country material requirements needed to fuel economic activities, covering both territorial‐ and demand‐b…
Spatial–temporal dynamics of the built environment toward sustainability
The urban built environment has accumulated massive amounts of resources, which is the main “hot spot” of construction materials and energy consumption in cities. To effectively monitor and manage resources use and waste disposal toward sustainability, this study intended to explore different metabolic paths of the urban built environment, as well as strategies for new and old urban areas separately with the help of material stock and flow analys…
Uncovering urban transportation infrastructure expansion and sustainability challenge in Bangkok
Development of transportation infrastructure that extends roads and railways in Bangkok has overlooked the negative environmental impact of construction material accumulation. To analyze the extent of this impact, we originally established road and railway's material intensity coefficients and investigated spatially explicit roadway and railway material stock (MS) for the years of 2004, 2009, 2014, 2019, and 2037, based upon the master plans’ tar…
What matters most to the material intensity coefficient of buildings? Random forest‐based evidence from China
Material intensity coefficient (MIC) is vital for material stock accounting in the field of industrial ecology. However, the categorization of MIC varies across regions especially for buildings that diverge greatly along the history and space aspect, and acquisition of MIC data and building information have always been a challenge in related studies. In this study, the state‐of‐art ensemble model “Random Forest” was developed on Chinese buildings…
From efficiency to equity
Transportation serves as a bridge for social production, distribution, exchange, and consumption and, thus, plays an important role in boosting the economy. In recent years, the rapid development of China's transportation system has driven a continuous accumulation of steel. In this study, we estimated the in‐use steel stocks of 32 types of infrastructure and vehicles in three subsystems (railway, road, and subway) in 31 provinces of China from 1…

CO 2 emissions from the Chinese cement sector
China is the largest producer and consumer of cement worldwide, and cement production entails the release of substantial carbon dioxide (CO 2 ) emissions. As the cement sector is a crucial sector of the Chinese economy, understanding the role of supply‐ and demand‐side factors may help accelerate efforts to mitigate CO 2 emissions. However, few studies have analyzed the critical factors affecting CO 2 emissions in the sector based on a combined s…
Transferability of Material Composition Indicators for Residential Buildings
Most anthropogenic material stocks and flows are associated with the building sector. Several recent studies have developed material composition indicators (MCIs) suitable for calculating material stocks and flows of the building sector using bottom‐up approaches, which hold great potential to provide information to support resource efficiency policies. A major limitation is the lack of country‐specific MCIs. This study aims to introduce a concep…

This study looks into material flow trends in the Philippines from 1985 to 2010 by utilizing the methodology of economy‐wide material flow analysis. Using domestic data sources, this study presents disaggregated annual material flow trends in terms of four major material categories, namely: biomass; fossil energy carriers; ores and industrial minerals; and construction minerals. The results describe in detail the growth of material flows in a hig…
Global Patterns and Trends for Non‐Metallic Minerals used for Construction
Despite accounting for almost 50% of global material use, nonmetallic minerals—mostly used for construction of buildings and infrastructure—are the material flow analysis (MFA) category with the highest uncertainty. The main reason for this is incomplete reporting in official national statistics because of ease of availability and the low per‐unit cost of these materials. However, the environmental burden associated with nonmetallic minerals, whi…
Estimating Materials Stocked by Land‐Use Type in Historic Urban Buildings Using Spatio‐Temporal Analytical Tools
The construction industry is an important contributor to urban economic development and consumes large volumes of building material that are stocked in cities over long periods. Those stocked spaces store valuable materials that may be available for recovery in the future. Thus quantifying the urban building stock is important for managing construction materials across the building life cycle. This article develops a new approach to urban buildin…
The Weight of Society Over Time and Space
In order to fully comprehend the socioeconomic metabolic (SEM) dynamics and material balance of nations, long‐term accounting of economy‐wide material stock is necessary in parallel to material flow accounts. Nevertheless, material stock accounts have been scarce, isolated, and mostly focused either on single materials, short time spans, or small regions. This study has two objectives: (1) review the state of the art of material stock research in…

Urban stock over time
A huge amount of construction material is required in urban areas for developing and maintaining buildings and infrastructure. Ageing stocks, which were built during a period of rapid growth in Japan (1955–1973), will cause a new waste flow in the near future. In order to assess urban metabolism with regard to building and infrastructure, it is necessary to understand change in its material accumulation both ‘spatially’ and ‘temporally’. In this …
