Just how low the VOC level needs to be for a given product to qualify for inclusion in GreenSpec depends on the product category. For most products, we require certification to California’s health-based emissions standard, CDPH Std Method v1.1 standard (also referred to as California Section 01350), which tests a product’s resultant VOC concentrations in the space after a given period of time. For wet-applied products like paints, caulks, and adhesives, we still also look for VOC content instead of, or in addition to, verified low emissions; this is because emissions testing doesn’t adequately test initial offgassing, and VOC content is currently the only widely available proxy.
Included here are various erosion-control products, foundation products that eliminate the need for excavation, and exterior stains that result in lower VOC emissions into the atmosphere. Fluorescent lamp and ballast recyclers and low-mercury fluorescent lamps reduce environmental impacts during maintenance and disposal of luminaires.
FormKote Emulsion is a water-based, freeze-thaw-stable, low-VOC (5 g/l), emulsified-chemical form-release agent offering a high coverage rate. Available in 55-gallon drums and five-gallon pails, this biodegradable product applies white and dries clear.
Conventional form-release oils can be a major source of VOCs, soil contamination, and human health risks. Increasingly, biodegradable, nonpetroleum alternatives are available.
These products contain just a fraction of the federally permitted VOC limit for concrete form-release agents. Many of these products produce a smoother finished surface with fewer "bug holes."
Products listed here are made with agricultural crops, are typically water-based and biodegradable, and have less than 60 grams per liter VOC.
