MRc4 - Recycle Content of Reinforcement Steel

KC - If your suppliers are unable or unwilling to provide information on the recycled content of any steel product, you can use the default recycled content value. As noted in the LEED Reference Guide, "For steel products where no recycled content information is available, assume the recycled content to be 25% postconsumer." See also the FAQ above "Is the default average recycled content value of 25% for steel still allowed?." You would take 100% of the cost of the reinforcement steel times the 25% to get its recycled content value.

Note that many steel products have a higher percentage of recycled content than the default but if you can't get that value, at least you have a fallback.
