Green Supply Chain Management


Around the world, interest in protecting the environment and in purchasing Green products is becoming more and more popular. In addition, governments continue to pass more comprehensive laws designed to protect the environment. Manufacturers are realizing how important it is to provide Green products made using Green practices.

Starting in the summer of 2005, D-Link launched our Green Environmental Protection management — D-Link Green. Our first steps were to improve environment management, Hazardous Substance Management, Waste Control and Recycling.

For environment management, D-Link demands that all our suppliers comply with ISO14001 regulations and to get ISO14001 certification within a certain period of time. We will review their performance regularly.

For Hazardous Substance Management, D-Link started with those substances restricted by EU legislation in electrical and electric equipment. We then added restricted hazardous substances from other regions. We have requested our supplies help us to monitor compliance.

For Waste Control and Recycling, we also included the 2002/96/EC into our product management.

In addition to being the first manufacturer to introduce Green design and Green manufacturing processes, D-Link also works closely with our suppliers through our Substance Management System to continuously update our Green design project and to comply with regulations globally. This is D-Link’s goal now and for the future.

Green at Every Step
Moving current technology in a greener direction is just the start. D-Link also wants greener designs and to convert our current supply chain to favor companies that support Green practices as well. D-Link Green combines these goals under the heading of Chemical, Energy and Recycling:

Through D-Link Hazardous Chemical Substance Management, we require our vendors to maintain strict standards. D-Link separates the environmental management materials as Level A and Level B.

Level A environmental managed material: These are restricted items. D-Link makes sure these hazardous substances follow worldwide country standards in order to be used in D-Link products, semi-finished products, components and packaging material. B Level environmental managed material: These are observed items. D-Link ensures that all current industry-restricted hazardous substances will not be used in D-Link products, semi-finished products, components and packaging material. It was been confirmed that these substances will adversely affect the environment and be detrimental to living organisms.

D-Link follows energy efficiency regulations to monitor the amount of energy our products use. We also use eco-friendly evaluations to develop eco-friendly proposals that prove and guarantee our Green commitment to consumers.

Eco-friendly design needs to be implemented into the product development from the beginning. At every step of the development process we consider the energy efficiency and options to reduce waste. We also use surveys to make sure we are developing the products our customers need.

D-Link is an ENERGY STAR® partner for end-use products incorporating single voltage external ac-dc or ac-ac power supplies. ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy helping us all save money and protect the environment through energy efficient products and practices.

D-Link Green products include a number of innovations to reduce energy consumption and implement special power-saving features:

  • With D-Link Green Technology, if there is no cable link or the link partners turn off, D-Link Green Technology will put that port in a "sleep mode," reducing power used for that port and saving energy.
  • If PCs connected to the switch/router are turned off, D-Link Green Technology can save up to 80% of the power used for each system.
  • D-Link Green Technology detects Ethernet cable length and adjusts power usage to save energy. This way, a port connected to a 20-meter cable only uses as much power as it needs, instead of using full power, which is only needed for 100-meter cables. If cable length is less than 20 meters, D-Link Green Technology can save up to 9.3% power used for each system.
  • Routers with D-Link Green Technology let you schedule Wi-Fi for only the times you need it.
  • When using a router with D-Link Green Technology, the SharePort™ feature lets users access a networked printer without needing to power on a host computer.
  • Storage enclosures with D-Link Green Technology take their own temperature and adjust the fan to provide only the cooling that is needed. The hard drives rest when not in use.
  • Photo frames with D-Link Green Technology shut down when no one's around to watch.
  • PowerLine HD adapters with D-Link Green Technology use the cabling you already have in your home and turn off when you are not sending data.


When consumers buy products, the first things to be thrown away are the package and unnecessary papers and accessories. These items are responsible for alarge amount of waste. In the regulation of WEEE in Europe, for example, we are currently focusing on the packaging, packaging waste and batteries.

D-Link Europe office utilizes local recycling vendors and provides them with detailed breakdowns of our products to aid in the recycling process. D-Link also implements the so called 3R concept in product development. We take the 3Rs — Recycle, Reuse and Recovery — into consideration in package design to reduce excess packaging. We also take the impact of the package waste into consideration, using thefollowing criteria:

  • Product weight and size
  • Usage of recycled materials
  • Energy consumption during the product life cycle
  • Ease of recycling
  • Estimation of waste produced
  • Air pollution impact
  • Water pollution impact
