If an event, or its vendors, is selling merchandise at an event, event organizers should consider the impacts of materials used to make the merchandise. Things to consider around merchandise are:

• reusability
  
• recyclability
  
• durability
  
• energy consumption
  
• efficiency of materials
  
• harmful toxins
  
• workers' welfare
  

This means that environmental and social considerations have been made and incorporated into the production of the merchandise.
