SERI is the housing body and ANSI-accredited Standards Development Organization for the R2 Standard, which is one of two accredited certification standards available for electronics recycling facilities (the other is e-Stewards; see https://www.epa.gov/smm-electronics/certified-electronics-recyclers#01 for more information on those standards and certified electronics recyclers). SERI recently announced that R2v3, the next version of the R2 Standard, was unanimously adopted by their board, and will be available for download from their web site on July 1, 2020.
See https://sustainableelectronics.org/r2v3 for further information, including 
information on the transition process for R2 certified facilities, the development process for the new standard, public comments, and the differences between the previous and new versions of the standard. Highlights of the proposed changes can also be found at https://sustainableelectronics.org/sites/default/files/Highlights%20Sheet%20-%20DRAFT%202%20%202019.12.20.pdf (the first page of this three-page document is pictured here).
