PEFC-Labelled Paper-based Bags

Sustainable Forestry

What is PEFC?

PEFC provides an assurance mechanism to purchasers of wood and paper products that they are promoting the sustainable management of forests. The PEFC Chain of Custody tracks certified wood content from forest to final product.

Why certify?

At Mondi we have made a public commitment to integrating sustainable development into our business model. From growing, harvesting and purchasing our raw materials, through our industrial production processes to branding and distribution, we are committed to providing our customers with the products they need at the lowest possible financial, environmental and social costs.
