I have found that a good way to wade through the myriad of options in carpets is to stick to looking for this label.
Here is a link to theCRI website, which has additional information on GreenLabel Plus and enables you to search specific carpets and brands as well. I hope this helps you in your search.
Remember the padding, too
With a church auditorium, you may be exploring commercial carpets for your application. One thing to remember is that you also want low-VOC padding, if you are planning on using padding.
Another important note: GreenLabel Plus is the industry certification for low-VOC carpet and does not necessarily address recycled content.
- A carpet that has a high recycled content might not be low-VOC, and vice versa;
- a low-VOC GreenLabel Plus carpet might not have much (or any) recycled content.
There may be additional products out there that are low-VOC, but it can be tough to verify this.
A salesperson may have some information on this for you, but I have found it helpful to confirm any sales information with documentation, since there can be confusing information out there.
