What is CARB PHASE TWO (P2) Board?
CARB stands for the California Air Resources Board. Known as the “clean air agency”, CARB is a department of the California Environmental Protection Agency. It was established in 1967 with the purpose of maintaining and improving air quality, and researching causes and solutions of air pollution. CARB2 is part of a two-phase implementation of California’s Composite Wood Products Regulation. In 2009, Phase 1 took effect.
Phase 2 started in 2010. In the same year, CARB2 became the national standard for reducing formaldehyde emissions. The goal of Phase 2 was reducing formaldehyde emissions further. For hardwood plywood, the emission level reduced to .05 parts per million.
