We are pursuing sustainability goals (and documentation of those goals) outside of any certification/rating system for a current project. However, we have set up a criteria list of goals by following strategies/credits from many of those systems (LEED v4 EPDs, SITES v2 threatened tree species, WELL v2 mindful eating, etc.). This approach is documented in our front end spec for Sustainable Design. Our contractor is concerned about "whether [client] can cite specific LEED requirements if LEED certification (and associated fees) are not part of the project." They are concerned it is a legal issue w/ USGBC. We haven't come across this before. I would greatly appreciate any thoughts or insight!
