Knowledge · Cobalt Hub

The open reference on artisanal cobalt.

Most of what is written about ASM cobalt is scattered across many places, often paywalled, and hard to see as a whole. The Cobalt Hub gathers it in one place: who the actors are, what is happening, what the evidence says, and what is being done about it.

Bringing it together

Why this hub exists.

Solid information on artisanal cobalt exists, but it is scattered: spread across reports, datasets, news, standards and project pages, in several languages, often behind paywalls or buried in passing mentions. Simply finding what already exists, and seeing how the pieces fit together, takes real work.

The Cobalt Hub brings it together in one place: a browsable registry of the actors, a database of initiatives, a library of the evidence, a map of the regulation, and a dated feed of developments. Every figure is sourced and dated, and every claim links back to where it came from.

It is built as a shared, open starting point for everyone working on artisanal cobalt, and it points outward to the people and organisations doing the work.
