Sustainable Bellingham's David MacLeod includes Climate Communications and Behavior Change in his list of recommended reading and has this to say about the guide: 

"I have thought a lot about the communication/behavior change problem, and have read a fair amount.  After a very brief skim of this document, it looks to me to be one of the most well thought out approaches along with being chock full of great practical suggestions. This looks to me like an essential blueprint that should be studied closely and applied widely! Read this document, and share it with your circles of influence!"
