Minerals and metals are ingredients necessary for the production of multiple goods and services that are essential to contemporary societies, feeding frequently complex global supply chains. The development of the modern, material-intensive lifestyles has led to a formidable acceleration of their production, particularly since the middle of the 20th century. Despite all the progress that can and needs to be done towards a circular, resource-efficient global economy, several important trends including:
demographic growth (United Nations
2019
),
the rapid development of the global middle class (Kharas
2017
),
growing urbanisation (United Nations
2018
) and
the transition towards a low-carbon global economy (Hund et al.
2020
)
point towards a continued, exponential growth of the global demand and production of minerals and metals (Christmann
2017
; Elshkaki et al.
2018
; Halada et al.
2008
; Hund et al.
2020
; Schipper et al.
2018
). Despite the efforts made by some producers and some authorities to strengthen the already important contribution of the minerals and metals industry to the UN Sustainable Development Goals (SDGs), the production of minerals and metals has negative impacts both on the global and on local ecosystems. It already contributes to 16% of global CO
2
emissions (OECD
2019
) and it generates about 50 bn t solid waste per year, 25 times the estimated annual amount of urban waste (Franks et al.
2021
). This waste is composed of mostly barren rock fragments, essentially overburden that needed to be stripped to access the ore, and of fine-grained ore processing tailings. The latter, if containing sulphides such as pyrite and residual minerals containing elements such as arsenic, cadmium, mercury, selenium or tellurium, can become highly problematic for the well-being of future generations. The production of minerals and metals also can be a source of conflicts and of social disruption. Failure to globally and sustainably manage the production of minerals and metals, in a transparent and multilateral framework providing a stable, foreseeable and level playing field for investors and for trade, could limit the capacity of the industry to reply to future demand and lead to potentially disastrous global conflicts. Depending on the practices of individual producers, on the quality of national and/or regional regulatory frameworks and on the effectiveness of their implementation, a same mineral or metal can be produced under very differing environmental and social conditions. Despite progress on sustainability performance reporting and of transparency of some parts of the industry, end-users of...
