Material transparency

Just as consumers have a right to know the contents of the food they consume (whether to avoid an allergic reaction or to make healthier nutrition choices), they should be able to find out what is in the products that make up the buildings they occupy.

This feature requires the disclosure of material composition as a step towards better product choices.
