Everyday when I open my inbox I find a new report or set of best practices relating to sustainability.  Here's one that from AASHTO (American Association of State Highway and Transportation Officials')  Center  Environmental Excellence that documents how state transportation departments, municipal planning organizations, and transit providers are putting into practice proven techniques that are speeding up project delivery and cutting costs while protecting and even improving environmental resources.

Leaner and Greener: Sustainability at Work in Transportation issued by AASHTO, in conjunction with the Federal Highway Administration and the Federal Transit Administration, showcases some of the many ways transportation agencies are simultaneously cutting costs, helping the environment, and strengthening communities.
