CARB stands for the California Air Resources Board. One of CARB’s missions is to reduce harmful air pollutants. It is tasked with developing and adopting regulations necessary to achieve healthful air quality. Their work has helped to cut 90% in black carbon in California since 1967.
What does CARB approved mean?
When a generator is certified to be CARB compliant, it meets the CARB standard to be sold in California. If you live in California, check the specification to make sure it is CARB compliant before you purchase a generator. If you don’t live in California, it is still a great idea to own a CARB compliant unit to help healthful air quality.
What does EPA III approved mean?
Similarly, the Environmental Protection Agency (EPA) has a somewhat similar but different set of air quality standards applied to the other 49 states.
Summary
CARB and EPA III are both air quality standards applied to generators and similar tools with combustion engines. CARB compliant is required in California. EPA III compliant in the other 49 states.
