The SOLER Group’s production sites are validated by Earthworm Foundation.

SOLER Earthworm Foundation

The SOLER Group is committed to total transparency in its supply and production chain. Thus, for many years, the NGO Earthworm Foundation France has been visiting the Group’s production sites to check them.

Implemented through the online platform Charcoal Transparency, Earthworm Foundation’s initiative aims to bring greater transparency to the European charcoal market.

Having achieved the best score in field observations (A++) for its Gyé-sur-Seine site, the SOLER Group is proud to be able to say that it produces “responsible” charcoal.
