Global socioeconomic material stocks rise 23-fold over the 20th century and require half of annual resource use

Significance A large part of all primary materials extracted globally accumulates in stocks of manufactured capital, including in buildings, infrastructure, machinery, and equipment. These in-use stocks of materials provide important services for society and the economy and drive long-term demand for materials and energy. Configuration and quantity of stocks determine future waste flows and recycling potential and are key to closing material loops and reducing waste and emissions in a circular economy.

We present a comprehensive estimate of global in-use material stocks and of related material flows,…
