The document discusses USGBC's LEED regionalization efforts, including:
1. The mission of the Regionalization Task Force is to identify regional sustainability issues and determine which LEED credits should receive extra points to address those issues, defined as Environmental Zones by zip codes.
2. The Task Force mapped Environmental Zones for states in the Heartland region and collaborated with other regional organizations to develop composite maps and lists of zip codes.
3. The interactive web-based maps developed by the Task Force will be an ongoing resource for the regions to enhance over time for future sustainability research.
