Alternatives for Option 1. material ingredient reporting

Jane, that would comply if it meets the requirements set out under the "Manufacturer Inventory" option. Have you reviewed the specifics of the SundaHus system with this in mind and compared them with the LEED requirement?

If a product do not contain ingredients listed on the REACH authorization or candidate list, can it contribute to both option 1 and 2 ?

No. The REACH path only covers optimization (option 2), not transparency (option 1).

Hi Paula, Do you know if Greenscreen benchmark and HPD are international labels that manufacturers outside the U.S. can use ? The manufacturers I contacted here (in France) do not know the existence of these programs and felt concerned about intellectual property.

Hi, Julien! The GreenScreen List Translator (which provides the screening tool for the HPD) as well as the HPD were both developed in North America but are available for anyone's use all over the world. The List Translator references hazard lists from global government agencies and NGOs. The HPD is totally open for use by anyone.Manufacturers who are concerned about revealing proprietary information can report hazard levels WITHOUT revealing the exact chemistry.Another option for them is the LEED-specific manufacturer inventory. In that framework, they report all ingredients, their function, and their quantity (% by weight). If there are ingredients they want to keep proprietary, instead of the chemical name and number, they need report any associated hazards, based on a GreenScreen List Translator screening.I hope this is helpful!
