What Is CARB?

The acronym CARB refers to the California air resources board, a state agency established in 1967 to oversee air quality and control pollution. However, the state of California’s commitment to tackling pollutants and promoting clean air dates back to as early as the 1940s with the inception of the Los Angeles County Air Pollution District. In the subsequent decade, the California Institute of Technology carried out studies that identified emissions from internal combustion engines as the primary source of air pollution. Consequently, California pioneered the introduction of tailpipe emission standards, becoming the first state to do so.

What is a CARB-Compliant Generator?

The California Air Resources Board (CARB) is in charge of managing all pollution-related concerns, encompassing both air and water issues. To accomplish this, CARB establishes up-to-date emission standards that generators are required to meet. Generators that meet these standards are labeled as CARB Compliant, whereas those that don’t are referred to as CARB Noncompliant. CARB Compliant generators have the advantage of emitting fewer harmful toxins, emissions, and particulates, thereby resulting in improved and healthier air quality.

What is the difference between compliant carbs and non-compliant carbs?

Adherence to CARB standards indicates that your equipment complies with the current emission guidelines set forth by CARB. Equipment that is CARB-compliant emits fewer harmful substances, toxins, and particles, leading to improved and safer air quality.

CARB strives to control the emission of:

  • Carbon monoxide.
  • Carbon dioxide (CO2).
  • Nitric oxides (NOx).
  • Sulfur oxides (SOx).
  • Hydrocarbons.
  • Particulate matter.

CARB-compliant generators are noted on the label for easy identification. To be legally sold in California, equipment must be CARB compliant. When purchasing equipment, you can check with the BISON generator manufacturers for CARB-compliant options.

what is the difference between carb and epa

What is the Difference Between CARB and EPA?

CARB is a Californian agency that oversees the regulation of emissions from generators and engines solely within California. The Environmental Protection Agency (EPA), a federal agency, administers laws related to emissions across the country. The key distinction between CARB and EPA lies in CARB’s significantly more stringent standards.

Engines and generators that comply with CARB regulations are more efficient and effective. While every engine manufactured or marketed in the United States must meet EPA standards, only California legally enforces CARB requirements. Residents of California are obligated to adhere to CARB, while all other states require compliance with the EPA. Generators that are CARB compliant are not just eco-friendly but also offer superior reliability.

Difference between CARB and EPA TIERS I, II, III, and IV

The EPA’s generator emissions monitoring diverges from CARB regulations in terms of Tier rules. While they have different requirements, both sets of regulations aim to reduce fuel emissions through their unique rules and guidelines. Diesel generators fall under the purview of EPA Tiers for equipment powered by nonroad diesel engines.

While EPA Tiers mainly pertain to diesel engines, including diesel generators, there are also natural gas generators manufactured that comply with EPA certifications, known as EPA Certified natural gas generator sets. The EPA Tiers demonstrate how alterations to engines over time have enhanced their eco-friendliness. Generator emissions should meet the strictest EPA Tier standards in place at the time of production.

  • Tier 1: In 1994, the EPA implemented the first federal emissions regulations for nonroad diesel engines with a rating of 37 kilowatts or above.
  • Tier 2: In 2001, the EPA introduced Tier 2, marking the initial phase in its goal to slash nonroad diesel engine emissions by up to two-thirds by implementing more rigorous standards than Tier 1.
  • Tier 3: Introduced in 2006, Tier 3 represented the next step in reducing emissions for nonroad diesel engines, gradually replacing Tier 2.
  • Tier 4: In 2008, the EPA’s Tier 4 emissions regulations established stricter standards for engine testing and operation, applying to diesel engines of all kilowatt ratings.


Complying with CARB regulations by using a CARB-certified generator is not only a legal requirement in the state of California, but also contributes to overall safety and environmental protection. It protects you from hazardous substances and helps the environment.CARB regulations help reduce air pollutants, which protects oxygen production in trees, and even prevents global warming by protecting ice caps.

CARB-Compliant: This refers to equipment that aligns with the emission standards as established by the California Air Resources Board (CARB). Such equipment is characterized by its ability to produce reduced quantities of harmful emissions, toxins, and particulates.

CARB-Noncompliant: In contrast, this refers to equipment that does not meet the stringent emission standards set by CARB.

The primary distinction between CARB-compliant and non-compliant equipment lies in their environmental impact. Specifically, CARB-compliant machines contribute to cleaner and safer air quality due to their lower emission levels.

To ensure you’re contributing to a healthier environment, consider opting for CARB-compliant equipment.
