Information & Communication Technology (ICT) has insatiable needs for minerals, both in quantity and diversity. One should note that most of those elements are also required for the sector of energy transitions resulting from the net-zero greenhouse gas emission goals, hence adding up to the demand. Nations regularly evaluate minerals for their criticality regarding energy production. Such critical minerals can exhibit a high risk of supply disruption for geological, political or technical reasons. At the same time, global availability of minerals is a pressing challenge, due to multiple factors, such as recycling limitations and mines' grade degradation. Unfortunately, research communities are still missing adequate analysis tools and metrics to properly evaluate and mitigate the mineral footprint of ICT, which is intrinsically multidimensional. This article aims to shed light upon the community's need to consider computing within mineral limits.
