How a company measures sustainable production will depend upon the particular product or service. The important items to measure are:

• The amount and type of material and energy being used--is it ecologically safe and being used at a sustainable rate?
   
  
• What types of wastes are being generated and what happens to them?
   
  
• How is land being used or reused by the product, service, or production process?
   
  
• Are workers valued and enhanced?
