The new Materials and Resources credit in LEED v4: Building Product
Disclosure and Optimization — Material Ingredients requires product
manufacturers to report material and chemical ingredients if they are to help meet
the requirements of the credit.

The NRMCA, through the support
of the Ready Mixed Concrete Research & Education Foundation,
commissioned this study to determine which program is best for the ready mixed
concrete industry.

This report has determined that concrete producers will have to obtain and report information on material ingredients and chemical constituents from their supply chain in an unprecedented way. In addition to presenting compliance paths, this report recommends the most practical and inexpensive pathway for the majority of concrete producers for establishing the necessary information for delivering on the credit criteria.
