Green Procurement

Green Procurement Policies

As part of our environmental target to convert all NEC products into environmentally sound items, we began a "green certification" system in FY 2003 based on the concept of procurement of low-impact materials through the low-impact manufacturing process by environmentally conscious suppliers. Since FY 2007, all the materials have been provided by certified suppliers. Moreover, we intend to apply the green certification system not only to material suppliers but also to intangible product suppliers such as software and service companies. In addition, we adopted an environmental rating evaluation system to give priority to green certification suppliers who also practice environmentally sound activities.

Green Procurement Policies

Essential Requirements for Procurement

Items Evaluated in Environmental Ratings

Items Evaluated
Creation of an environmental management system
  1. Develop environmental policies.
  2. Set up an environmental management organization and appoint an environmental representative.
  3. Identify and comply with environmental laws and regulations.
  4. Carry out environmental objectives, targets and plans.
  5. Conduct environmental education and training for employees.
  6. Periodically confirm the status quo of legal compliance and environmental activities.
Appropriate management of environmental pollutants used in manufacturing process Environmental pollutants used in the manufacturing process should be managed according to the following two categories 1 and 2
  1. Non-use of banned substances
  2. Reduction of substances to be avoided
Implementing the product environmental assessment
  1. Appropriate management of the environmental pollutants contained in products
  2. Resource and energy conservation
  3. Long lifetime
  4. Use of recycled parts and materials
  5. Easily recyclable materials
  6. Labeling plastic type
Commitment to global environmental conservation
  1. Reduction or complete elimination of the substances that may cause global warming
  2. Reduction in waste generation
  3. Management of chemical substances
  4. Reduction in resource consumption
  5. Reduction in the impact of package and packaging materials upon environment
  6. Environmental assessment
  7. Consideration to biodiversity conservation

Public disclosure of environmental information

Green Procurement Guidelines

To enforce green procurement, NEC established Green Procurement Guidelines as - Green Procurement Guidelines for Suppliers.

Chemical substances concerned by the Green Procurement Guidelines are shown in an overview table below.
Especially NEC specified Standards Pertaining to Procurement Restrictions for the Inclusion of Chemical Substances in Products in order to comply with laws in many countries which restrict containing specific chemical substances in products. NEC will revise the Standards to fulfill the trend of the laws periodically. Suppliers are requested to watch the latest version of the Standards.

Thank you in advance for your kind cooperation.

Green Procurement Support System

Environmental information regarding the status of environmental pollutants contained in parts received from suppliers, etc., is registered in a database. Designers can access this database from their own terminals through an in-house information network and use this database to select parts and materials with excellent environmental characteristics, as well as to check the status of environmental pollutants contained in products and materials. This allows them to evaluate their adequacy for product assessments.
