Ricoh first published Green Procurement Guidelines in 1998 and updated them in 2002 as the Green Procurement Standard to minimize the environmental impact of raw materials, parts, and products. The standard focused on pollution prevention, resource conservation and recycling, and energy conservation. It required suppliers to establish environmental management systems. Ricoh works with suppliers and customers to produce sustainable, low-impact products throughout the manufacturing process and comply with EU environmental legislation and regulations on banned substances, chemicals, and hazardous materials in electronic products.
