The relationship between the fresh air we breathe and the type of generator we choose may not be obvious, but the two are inextricably linked. A CARB-compliant generator is a generator that meets stricter environmental standards for power generation equipment set by the California Air Resources Board. This standard requires power generation equipment to reduce harmful emissions, toxins, and particulate matter to ensure cleaner, safer air quality. As a result, CARB-compliant generators use advanced technology, operate more efficiently, and significantly reduce greenhouse gas emissions.

You may also be confused by the term “CARB compliant” in your generator owner’s manual. Well, follow BISON now to learn what CARB-compliant generators are, and their role and importance in reducing air pollution and achieving a sustainable future.

What is CARB?

The acronym CARB refers to the California Air Resources Board, a state agency established in 1967 that enforces air quality standards stricter than the federal Clean Air Act, which was enacted that same year. 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. Today, CARB has grown into a pioneering force in environmental protection, with comprehensive air quality regulations covering all major sources of air pollution, including smog-forming compounds and greenhouse gases.

What is a CARB-compliant generator?

The California Air Resources Board (CARB) enforces air quality standards for generators and related equipment. 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.

The certification process for this type of generator involves rigorous testing and verification procedures. The certification process includes detailed documentation of equipment specifications, comprehensive emissions test data, and verification of the effectiveness of the emission control system. In addition, manufacturers must also provide clear labels on their equipment to indicate that they comply with CARB standards so that consumers and regulators can easily identify certified products.

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

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 (CO).
Carbon dioxide (CO2).
Nitric oxides (NOx).
Hydrocarbons (HC).
Particulate matter (PM).

To this end, when BISON produces generators, the detailed design and production processes will be upgraded. In addition, CARB-compliant generators are noted on the label for easy identification. For mandatory compliance requirements in California and other states that follow CARB standards, when purchasing equipment, you can consult the BISON generator supplier to learn about CARB-compliant options.

Benefits of a CARB-compliant generator

As a solution, CARB regulations permit the use of backup generators to compensate for grid power loss. However, these generators, which run on combustible fuels with high greenhouse gas emissions, can deteriorate air quality and pose risks to public health.

Generators that comply with CARB regulations tackle all these issues simultaneously, offering environmental, health, and financial gains. Even outside of California, choosing a CARB-compliant generator carries several benefits:

Extended, cleaner power supply — CARB-compliant generators are typically 5–10% more fuel-efficient due to optimized combustion and electronic fuel management.
Reduced environmental pollution — Users don’t have to compromise their surroundings if they require backup power during a power outage.
Minimized health hazards — Generators that run cleaner pose less threat to individuals with respiratory or cardiac issues, avoiding the sulfuric oxide and carbon monoxide exposure tied to noncompliant units.
No sanction risks — The sale or acquisition of a generator that does not meet CARB requirements may result in fines, depending on state, territory, or local regulations.
Superior machinery parts — Components for CARB-compliant generators are designed for optimal fuel efficiency, reliability, and the cleanest possible operation.

How do you choose a CARB-compliant generator?

Choosing a CARB-compliant generator involves focusing on several crucial aspects, so companies and organizations can make a well-informed choice.

Confirm compliance: The initial step in selecting a CARB-compliant generator is ensuring that it adheres to the emission regulations established by the California Air Resources Board (CARB). Keep an eye out for a CARB compliance label or certificate on the generator or provided by the manufacturer.

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 in the United States must meet EPA standards, Only California legally requires CARB compliance, but more than a dozen states (16+) have adopted CARB standards under Clean Air Act Section 177 — so compliance matters well beyond California.

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

The EPA’s monitoring of generator emissions 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: The EPA adopted its first nonroad diesel emissions standard, Tier 1, in 1994 for engines rated at or above 37 kilowatts.
Tier 2: Adopted in 2001, Tier 2 marked the initial phase in the goal to slash nonroad diesel engine emissions by up to two-thirds compared to Tier 1, implementing more rigorous standards than its predecessor.
Tier 3: Introduced in 2006, Tier 3 represented the next step in reducing emissions for nonroad diesel engines, gradually replacing Tier 2.
Tier 4: Tier 4 (phased in from 2008, with final standards applying through 2014–2015 by power rating) established the strictest testing and operation standards for nonroad diesel engines. Tier 4 cuts NOx by ~90% and PM by ~90% compared to Tier 1.

Conclusion

Complying with CARB regulations is a legal requirement in California and increasingly in other states that adopt CARB standards. CARB regulations help reduce air pollutants, which protects oxygen production in trees and even prevents global warming by protecting ice caps.

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.
