The Wakefield-based company, which already holds FSC and PEFC awards, said achieving ISO 14001 was a clear demonstration of the company's commitment to incorporate such standards.

Jim Algar, managing director of Polestar Chantry, added: "We believe in adopting robust and sustainable environmental policies and procedures as our customers are increasingly requesting information and confirmation of our environmental management status during contractual negotiations and awards."

He said: "We will of course continue in our drive to improve environmental processes and enhance our profile to support the wider Polestar group and print sector as a whole."
