The U.S. Green Building Council (USGBC) is offering to refund standard certification review fees of up to $30,000 for the first projects certified under its LEED green-building program in 112 countries where LEED has yet to take root.

Dubbed “LEED Earth,” the three-year campaign, which will end June 5, 2016, is open to all building types across the suite of LEED rating systems.

For the campaign’s rules and regulations, go to http://bit.ly/LEED_Earth. To register a project, contact the USGBC at LEEDEarth@usgbc.org.
