Use a minimum of 20%, by cost, of at least 3 building product and material types meeting one of the options below.

Option 1. Manufacturer declared disclosure

Use building products and materials with manufacturer provided disclosure of chemical compounds that meet Clean Production Action’s Green Screen v1.2 Benchmark 1: Avoid Chemicals of High Concern criteria. The disclosure statement shall include homogeneous materials that make up at least 99% of the material by weight. Calculate compliant building products and materials at half of their cost.

Option 2. Third party certified disclosure

For Product Formulators:
Chemicals to be disclosed are those that are intentionally added, plus known residuals, in concentrations of 0.01% by mass (100 parts per million (ppm)) within each of the homogeneous materials. Disclosure can either be listing by CAS number of by hazard communication based on the Green Screen v1.2 Benchmark 1: Avoid Chemicals of High Concern.
