The document outlines four options for building material reuse and optimization. Option 1 describes using environmental product declarations for building products. Option 2 involves using products that minimize environmental impacts or are locally sourced. Option 3 requires reporting on raw material sources and commitments to environmental responsibility. Option 4 addresses optimizing building products by eliminating hazardous materials.
