Mondi uncoated fine paper sales and marketing director Mark Ushpol said the accreditations are evidence of the company's commitment to sustainable practices.
He said: "From growing, harvesting and purchasing raw materials, through industrial production processes to branding and distribution, we are committed to providing products at the lowest possible financial, environmental and social cost."
Mondi's offset paper is available in a range of formats and weights. It also produces the Green Range products.
Its uncoated fine paper mill in Ruomberok, Slovakia, has also built an offset centre.
