Here's some more dd that might help a bit with the confusion of others claiming to have "green" poly as well. It's been an issue for a long time for companies making false claims. Hybrid however is backed by the EPA and in 2011 was noted to be the solution to isocynates when using poly.

This link also shows a little bit about Mary Cushmac's role as well on cracking down on isocynates! I am busy at work, past few days have been crazy but I will try and get more dd out on this board when I get more time!
