Green Seal
Both Van Morrison & Kermit the Frog know that bein' green isn't easy. However, for clients whose businesses are environmentally-conscious, there exists the Green Seal website to help them out. Its home page describes this group as "an independent non-profit organization dedicated to safeguarding the environment and transforming the marketplace by promoting the manufacture, purchase, and use of environmentally responsible products and services." If your client has an environmentally-friendly product, a link exists to information as to how they can get a Green Seal certification to add to the product's resume. If your client seeks a "green" product, a link exists to a member directory that'll help find out who sells it.
