Product Assessment

To minimize the adverse environmental effects of our products throughout their life cycles (see right diagram), Nikon formulated its own product assessment system in 1995.
The Nikon Product Assessment system is now practiced by all product development and design departments. The resulting reductions in the environmental loads of our products have been significant.
Nikon is constantly adding new evaluation items and standards for product assessment. In the year ended March 2007 we introduced a revised system (8th update) with reinforced criteria related to hazardous substances. Our product design divisions will redouble their efforts with the goal of more favorable evaluation under assessment by the newest update.

Features of Nikon Product Assessment System

  • Priority placed on reducing consumption of resources and energy, recycling, long product life, reduction in use of hazardous substances, reduction and simplified processing of waste; disclosure of material information
  • Anticipation of emerging global environmental issues and alteration of regulations/rules in foreign countries, and development of Nikon standards that take the characteristics of our products into account
  • Formulated after thorough discussion among product development teams, material engineers and other related personnel
  • Make product assessment mandatory in design reviews and related phases of product development sequences, with procedures and standards clearly defined
  • Vigilance in product improvement from one model to the next
  • Support designers by building and maintaining an environmental data book of material information (Eco-glass, plastics, metals, surface treatment materials, bonding agents, etc.), explanatory text and documentation

Items Covered Under the Nikon Product Assessment

  • Ongoing reductions in product mass, volume, and part counts
  • Assessment and improvement of energy consumption based on Nikon's Energy Efficiency formula (product functionality/ power consumed)
  • Pursuit of extended product life and simpler repair procedures
  • Reduction in the amount of waste generated from consumables; appropriate guidance on waste processing for customers
  • Simplified recycling procedures (simpler separation of plastics from metals, content marking/explanation, and simpler removal of rechargeable batteries)
  • Avoidance of the use of hazardous substances (heavy metals in materials such as metal, resin, electric wire, electronic components, etc., specific brominated flame retardants and PVC)
  • Use of optical glass free of lead and arsenic
  • Transition to lead-free solder on boards for electronic components
  • Adoption of surface-treatment technologies free of hexavalent chrome
  • Elimination of ozone-layer-depleting substances
  • Strict observance of environmental laws and regulations (battery regulations, RoHS Directive and others)
  • Overall assessment (overall assessment points, comments on evaluation, etc.)

Results of "Nikon Product Assessment"

Product Assessment Results

If a product shows improved environmental friendliness compared with the prior model, assessment points are awarded. If the environmental friendliness is about the same, no points are given. If the environmental friendliness has deteriorated, points are subtracted. The point scale ranges from -100 to +100.
Over the 13 years from the year ended March 1996 to the year ended March 2008, Nikon performed 815 assessments under this program, obtaining +26.6 points on average. The average points assessed have improved dramatically over the last four years, reaching +47.6, in spite of the enforcement of ever stricter assessment criteria.
Nikon is continuing its efforts to improve and enhance the functionality and performance of all of its products, while releasing new products to the world markets. These assessments confirm the great advances we are achieving through our environmental efforts.
