 The phrase "cradle to cradle" itself was coined by Walter R. Stahel in the 1970s.The current model is based on a system of "lifecycle development" initiated by Michael Braungart and colleagues at the "Environmental Protection Encouragement Agency" (EPEA) in the 1990s and explored through the publication "A Technical Framework for Life-Cycle Assessment".In 2002, Braungart and William McDonough published a book called "", a manifesto for cradle-to-cradle design that gives specific details of how to achieve the model.
