Natural materials such as solid wood, stone, clays, etc. all have advantageous material attributes in terms of transparency and health. There does not appear to be any mention of natural materials in the BPDO - Material Ingredients credit. If a solid stone building product is specified, for example, does it automatically meet Option 1 for Material Reporting or Option 2 for Optimization? I recognize that FSC wood product and qualifying bio-based materials are addressed in the Sourcing of Raw Materials credit.

Currently, untreated and natural stone and wood products can count for both Option 1 and Option 2 of this credit, provided you can prove that they are free of any additives. Expect that additional guidelines and definitions will be developed to address natural materials in the future.

John, has any additional information (i.e., published guidance, interpretations, addenda, etc.) regarding natural materials, especially stone, been posted?
