SMaRT Sustainable Products Standard

Yes - the SMaRT standards have been around for a while: http://www.sustainableproducts.com/smartweb.html

They look at the products in more of an overall sustainable manner; meaning they don't just look at product emissions or recycled content or durability - they look at the complete picture. It would probably qualify for points under Pilot Credit 43.

SMaRT emerged at the same time as the development of the first Environmentally Preferable Product standard for carpet, now known as NSF 140 - Sustainable Carpet Assessment Standard.
The standards are loosely similar however NSF 140 has been more broadly adopted and most major carpets are certified to NSF 140.
Resilient flooring is covered by NSF/ANSI 332 Sustainability Assessment for Resilient Floor Coverings.

It does not appear that meeting CRI Green Label Plus low emitting criteria is a requirement for SMaRT, it is an optional credit, therefore you will want to ensure that the product also meets the required low emitting criteria for IEQ c4.3.

There is a CIR for an Innovation in Design credit for SMaRT which has a similar threshold as C2C products. CIR #1768, dated 6/6/2007 and it is applicable to NC, CI, Schools, and CS under LEED v3.

The CIR is for an innovation in design credit, not for using SMaRT to meet IEQc4.3. Your flooring will need to demonstrate that it meets the required low emitting criteria in order to earn IEQ 4.3.
