Just found out that the folks at Higher Ground Roasters in Traverse City, MI are donating a percentage of sales from their TC 350 blend to a Michigan-based organization (350.org) that's geared to reducing carbon emissions.  No mention of the percentage donated. 

Apparently, from the site:

"350 parts per million is the “red line” for our atmosphere’s carbon dioxide content, and we must get back to that number quickly to ensure a healthy future for our planet."
