This session explores the process of developing and early implementation of climate change design guidelines (CCDG) for City and County of Honolulu (City)'s capital projects, highlighting lessons learned, challenges identified, and opportunities to address related needs. Attendees will gain insight into how the City's CCDG were developed from concept to early implementation, what's in the CCDG, and how they work. Key discussion points will also include reflections on what we've learned so far about getting people to use this new resource, building buy-in, and embedding climate considerations into existing systems.
