The Green Button Alliance (GBA) is a non-profit, U.S. IRC 501(c)(3) corp­oration formed in 2015 to foster the develop­ment, compliance, and widespread adoption of the Green Button standard.

It is the single, definitive go-to-place for all things related to the Green Button initiative—from cert­ification of implementa­tions to marketing and education.
