A message from Tommy to all members of on Barista Exchange!

Ok, so for Purest, we want the world to be more green : )!!YEP so we came up with a committment of giving incentives to our customers..and it's working..so i thought i would share them with the group. We ask the customers to join in on the greening effort, bring their own cups, promote sustainable practices where they work at...and get 15% off on all drinks. If you guys got any other ideas, please let me know! thanks

The above was sent to me as an email and I couldn't find if it was part of a discussion.  

My reply; 
What about asking customers to pay a little more to support green initiatives in your shop; i.e. putting in a solar panel

Maybe having a specific drink(s) on the menu, stating that $0.25 or a % of each drink sold goes to your shops green-initiative fund.  

I also came across this site http://www.transitionnetwork.org 

The concept make sense, its local and community based. I wonder if a group of local businesses got together to form a Network?
