This resulted in EcoVadis awarding the Group with a silver rating.

For the remaining print communication media, HighCo encourages the best environmentally-friendly communication practices by choosing paper from sustainably managed forests and selecting printers with the Imprim’vert label.
Commitment to culture
The Group's cultural commitment extends beyond the borders of Provence. For the past six years, HighCo has been putting together an impressive collection that aims to encourage street artists to express the very mainstream world of consumer goods.
