Of 47 product categories identified for possible emissions reduction, 21 have been presented as part of public work group meetings aimed at reducing VOC emissions.

The California Air Resources Board (CARB) is required to regulate consumer products as part of the California Clean Air Act. As part of their responsibility, CARB must provide technologically and commercially feasible solutions to reduce volatile organic carbon (VOC) emissions from consumer products.

With the exceptions outlined in the regulation, a VOC is defined as any compound containing at least one atom of carbon. The current strategy requires additional VOC reductions to consumer products to achieve a goal of 1-2 tonnes per day (tpd) by 2023 in the South Coast region, as well as an 8-10 tpd reduction state-wide by 2031 (including 4-5 tpd reduction in the South Coast).

To identify promising consumer product categories for meaningful emission reductions, CARB conducted a survey consisting of 491 categories, 1400 company respondents, and more than 1 million consumer products. The survey identified 47 categories where VOC reductions may be possible. CARB has held Public Work Group Meetings to present the survey data and liaise with stakeholders on the possible impacts of additional limits on VOCs in consumer products.

The first 21 categories were presented during May and June 2019, and the current and proposed VOC limits are outlined below. Not all the product categories discussed are necessarily going to become the subject of new or additional regulation. Currently, CARB is encouraging stakeholders to take part in the public meetings or meet with them directly to discuss opportunities, challenges and/or regulatory approaches related to these product types.

In addition to discussion surrounding the potential impact on existing formulations if VOC limits are reduced, the subject of the fragrance, its definition and exemption status are also being discussed. To date, CARB has considered fragrance to be made up of 100% VOC and has advised they would continue to work with the industry to better understand the composition of fragrance mixtures. Additionally, as part of the upcoming rulemaking, a monoterpene guidance document intended to clarify the applicability of the fragrance exemption is being considered as it relates to general purpose cleaners and degreasers. The proposed guidance may either confirm that specified monoterpenes are not to be considered within the fragrance exemption, to reduce the fragrance exemption with an allowance for monoterpenes, to eliminate the fragrance exemption and slightly increase VOC limits, or to provide other guidance on this topic.
