Identifying strategies for reconciling human development and climate change mitigation requires an adequate understanding of how infrastructures contribute to well-being greenhouse gas emissions. While direct emissions from infrastructure use are well-known, information about indirect their construction is highly fragmented. Here, we estimated the carbon footprint existing global stock in 2008, assuming current technologies, be 122 (-20/+15) Gt CO2. The average per-capita industrialized...
Steel production accounts for 25% of industrial carbon emissions. Long-term forecasts steel demand and scrap supply are needed to develop strategies how the industry could respond industrialization urbanization in developing world while simultaneously reducing its environmental impact, particular, footprint. We developed a dynamic stock model estimate future final available 10 regions. Based on evidence from countries, we assumed that per capita in-use stocks will saturate eventually....
Identifying strategies for reducing greenhouse gas emissions from steel production requires a comprehensive model of the sector but previous work has either failed to consider whole supply chain or considered only subset possible abatement options. In this work, global mass flow analysis is combined with process intensities allow forecasts future under all Scenario shows that capacity primary already near peak and if sectoral are be reduced by 50% 2050, last required blast furnace will built...
In recent years, increasing attention has been given to the potential supply risks of critical battery materials, such as cobalt, for electric mobility transitions. While technology and recycling advancement are two widely acknowledged strategies addressing risks, extent which they will relieve global regional cobalt demand-supply imbalance remains poorly understood. Here, we address this gap by simulating historical (1998-2019) future (2020-2050) cycles covering both traditional emerging...
Sand, gravel, and crushed rock, together referred to as construction aggregates, are the most extracted solid materials. Growing demand is damaging ecosystems, triggering social conflicts, fueling concerns over sand scarcity. Balancing protection efforts extraction meet society's needs requires designing sustainable pathways at a system level. Here, we present perspective on global sustainability that shifts focus from mining site entire sand-supply network (SSN) of region understood coupled...
Abstract The global energy transition relies increasingly on lithium-ion batteries for electric transportation and renewable integration. Given the highly concentrated supply chain of battery materials, importing regions have a strategic imperative to reduce their reliance material imports through, e.g ., recycling or reuse. We investigate potential vehicle-to-grid second-life resource use by displacing new stationary dedicated grid storage. Based dynamic flow analysis, we show that...
Metallurgical iron cycles are characterized for four anthropogenic life stages: production, fabrication and manufacturing, use, waste management recycling. This analysis is conducted year 2000 at three spatial levels: 68 countries territories, nine world regions, the planet. Findings include following: (1) contemporary basically open substantially dependent on environmental sources sinks; (2) Asia leads regions in production use; Oceania, Latin America Caribbean, Africa, Commonwealth of...
Stocks of products in use are the pivotal engines that drive anthropogenic metal cycles: They support lives people by providing services to them; they sources for future secondary resources (scrap); and demand in-use stocks generates metals. Despite their great importance impacts on other parts cycles environment, study has heretofore been widely neglected. Here we investigate geogenic iron United States (U.S.) analyzing cycle over period 1900-2004. Our results show following. (i) Over last...
The anthropogenic nickel cycle for the year 2000 was analyzed using a material flow analysis at multiple levels: 52 countries, territories, or country groups, eight regions, and planet. Special attention given to trade in nickel-containing products different stages of cycle. A new circular diagram highlights process connections, role potential recycling, relevance life stages. following results were achieved. (1) is dominated by six countries territories: USA, China Hong Kong, Japan,...
This paper discusses the use of Material Flow Analysis (MFA) as a tool to support policy decision making in field resource and environmental management. In terms policy, MFA can be used for early recognition, priority setting, analyse improve effectiveness measures design efficient material management strategies view sustainability. has high potential implemented guiding at regional level, example part audit system or Local Agenda 21 process. based on is complementary traditional strategies,...
As the world's largest CO(2) emitter and steel producer, China has set ambitious goal of establishing a circular economy which aims at reconciling economic development with environmental protection sustainable resource use. This work applies dynamic material flow analysis to forecast production, recycling, iron ore consumption in Chinese cycle until 2100 by using services terms in-use stock per capita as driver future development. The whole is modeled determine possible responses industry...
A dynamic material flow model was used to analyze the patterns of iron stocks in use for six industrialized countries. The contemporary stock remaining countries estimated assuming that they follow a similar pattern per economic activity. Iron have reached plateau about 8-12 tons capita United States, France, and Kingdom, but not yet Japan, Canada, Australia. global average determined be 2.7 capita. An increase level 10 over next decades would deplete currently identified reserves....
The architecture, engineering and construction industry is a major producer of waste, consumer primary materials. This study presents method for analysing the dynamics both floor area material use in residential housing. population's demand housing represents driver system, subsequent effects on stocks flows building materials Norway are investigated from 1900 to projected demands 2100. Results show that knowledge about past activity levels important projecting future levels. Scenarios...
Material cycles have become increasingly coupled and interconnected in a globalizing era. While material flow analysis (MFA) has been widely used to characterize stocks flows along technological life cycle within specific geographical area, trade networks among individual remained largely unexplored. Here we developed trade-linked multilevel MFA model map the contemporary global journey of anthropogenic aluminum. We demonstrate that aluminum depends substantially on international all forms...
A dynamic material flow model was developed to simulate the evolution of global aluminum stocks in geological reserve and anthropogenic reservoir from 1900 2010 on a country level. The contemporary stock use (0.6 Gt or 90 kg/capita) has reached about 10% that known bauxite reserves represents an embodied energy amount is equivalent three-quarters present annual electricity consumption. largest proportions in-use are located U.S. (28%), China (15%), Japan (7%), Germany (6%) sectors building...
