Denplan, a dental payment plan provider based in Winchester, employed 350 staff and sought ISO14001 certification for environmental management. They had an existing "Green Team" implementing energy, water, and paper reductions, but it lacked resources. To achieve certification, Denplan established environmental policies, identified impacts, set targets, improved monitoring, and communicated changes company-wide with champions. As a result, over 70% of waste was recycled and energy-efficient lighting was installed, though energy use increased with IT.
