ZeroVOC

ZeroVOC is a term used to describe products that are designed to emit little or no volatile organic compounds, with a focus on indoor air quality. It is commonly applied to paints, primers, sealants, adhesives, wood finishes, coatings, flooring products, and certain cleaning agents used indoors. The exact meaning of zero VOC varies by standard or certification program, but it generally implies that the finished product contains no VOCs above the detection limit of the test method or below a defined maximum. In practice, “zero” often means 0 g/L or a very small limit set by the program, though some programs allow a slightly higher, specified maximum.

VOCs are organic compounds that can evaporate at room temperature, contributing to odors, air quality concerns, and potential health effects in some individuals. The list of compounds considered VOCs can differ by jurisdiction and program, which affects how a product is categorized as zero VOC.

Measurement and verification rely on standardized testing methods recognized by environmental agencies and certification programs. Manufacturers report VOC content for the finished product, and independent certifications may audit production and labeling to maintain credibility.

Limitations and caveats include the possibility of off-gassing after application or curing, which may extend beyond the final VOC content of the product. Packaging materials, storage, and application conditions can influence emissions. Additionally, “zero VOC” claims may not cover all components or emissions associated with a product’s use.

Certifications from programs like GREENGUARD, Green Seal, and other green-building standards are commonly used to verify zero VOC claims and support indoor air quality goals. See also VOC, indoor air quality, and green building certifications.
