I'm very pleased to see this credit (the last one in Table 2 above) added to the mix. I think it represents an important advance for the LEED system in bringing healthy materials to building projects, encouraging both content disclosure and screening for chemicals of concern. It rewards building projects with one point toward LEED certification if 20% of all building products and materials, by cost, have a publicly available list of ingredients and do not include California Proposition 65 chemicals in their contents.

This is a great start. In the next few weeks I'll be suggesting ways to refine it (definitions for what it means to fully disclose contents, some other red lists to consider beyond Prop 65, etc) and will be interested to see more discussion here.
