The U.S. Green Building Council is calling for proposals to help craft the next iteration of its 20-year-old LEED green building program.

In addition, the ratings group plans to hold an educational session on the future of LEED at its Greenbuild conference, Nov. 19-22, in Atlanta. The session’s content will include a review of the proposals submitted online.

Proposals can be submitted online at usgbc.org.
