Climate Change, Energy Policy and Sustainability event series: Small Miners, big opportunities?

Small Miners, big opportunities? Exploring the potential role of the Artisanal and Small-Scale Mining Sector in Sustainable Critical Mineral Value Chains.

The low-carbon transition is driving increased demand for a more diverse range of so-called ‘critical mineral’. It is the specific materiality of this transition that has led to these minerals being described as ‘critical’ – where security of supply is seen as particularly crucial or subject to range of political or economic risks. The imperative of the low-carbon transition, however, means that the definition of ‘criticality’ rather than being country-specific, now reflects issues of global demand and supply and price variability, as well as specific ‘value chain’ issues including governance and power emanating from the supply of each individual mineral.  

Many of these critical minerals are supplied in part by artisanal and small-scale mining (ASM) operations. Although it is a largely informal source of livelihood for many (over 40 million people globally on some estimates), and plays a significant role in global mineral supplies, the ASM sector has until recently been largely overlooked in mainstream development discourse and policy interventions, as well as in academic literature. This talk will argue that the neglect of the ASM sector is at best unfortunate, and at worst deeply worrying, given the unprecedented speed of change in global energy systems. But, while the ASM sector will be essential for bridging future supply gaps in critical minerals, its expansion outside formal regulatory frameworks presents challenges related to potential environmental impact, social inequalities, reputational risks and value-chain governance which need to be explored.
