Sourcing of Raw Materials is a streamlined, more achievable version of the LEED v4 credit. The v4 credit had an unachievable Option 1 (for corporate sustainability reporting), and a 2nd option that required 25% of products by cost to meet a variety of environmental metrics. However, it limited the ability of structural and envelope products to comply. The good news? The Sourcing of Raw Materials credit is now pretty achievable. It tends to be easier on new construction projects, but plenty of interiors projects are navigating this as well.
