Why does GEI use TVOC as a product criterion?
While GREENGUARD Certification programs review products for more individual VOCs than any other product certification program, they also consider the sum of all VOCs released from a product which is reported as total volatile organic compound (TVOC). This includes chemicals for which government or public health organizations have not yet established acceptable criteria. The use of TVOC, as a certification criterion, minimizes the total amount of VOCs a product is allowed to emit. The use of TVOC further harmonizes GREENGUARD standards with global requirements, which also rely on this criterion.
