Website: Environmentally Preferable Product Purchasing List

It may be a joint project of the Pacific NorthWest Economic Region, the Northwest Pollution Prevention Resource Center, and the Washington State Department of Ecology, but this online guide to environmentally preferable products doesn't limit itself to suppliers and manufacturers in the Pacific Northwest. Many operate nationally. All have been recommended by a third-party organization.

Enter a primary category of interest -- such as cleaning products, office supplies, etc. -- then follow the prompts to narrow your search. Product descriptions cover cost analysis and availability as well as environmental pros and cons -- and offer success stories from companies that have used the products.

Also on the site: Find an introductory backgrounder on environmentally preferably purchasing, case studies, and tips for buying green.
