Our commitments are omnipresent

The stakes are high and we must participate and encourage one another to change our way of working. It’s obvious: when you love wood, you love nature and those who live in it. It is not enough that our raw materials come from well-managed forests; we act for the environment every day. As in all great families, Burger & Cie takes care of its own, and of future generations.

Reflection. Actions.
