You Want to Be CARB Compliant: Everything You Need To Know

Suppose you are an operator of a CARB-compliant business. Congratulations! You will now be able to reap the benefits that come with operating in a CARB-compliant environment. If you aren’t CARB compliant yet, don’t worry; this blog post will tell you everything you need to know about CARB compliance and how to become CARB compliant.

What Is CARB?

CARB is the California Air Resources Board (CARB for short). The state agency is charged with protecting public health and welfare by ensuring air quality. CARB has established CARB compliant emission limits for various sources, including equipment such as boilers, engines, power plants, and other industrial processes.

CARB History

The California Air Resources Board (CARB) was formed in 1967 through the Bureau of Air Sanitation merger with the California Motor Vehicle Pollution Control Board. To combat pollution (smog) in California, particularly the southwest basin (LA and surrounds), it was authorized by Ronald Reagan.

The Federal Air Quality Act of 1967, signed into law by President Ronald Reagan on October 27, 1970, gave California the option to go above and beyond federal air quality standards and begin research and monitoring air pollution.

The CARB’s main objectives are to:

  • Achieve and maintain optimal air quality;
  • Provide a safe breathing environment to the public;
  • Give creative ideas for following air pollution laws and standards.

So, now that you know what CARB stands for, what it is, and its goals, let’s look at why it wants to control TRUs.


The Environmental Protection Agency (EPA) is a federal department regulating all environmental concerns in the United States, including air and water pollution. This department was founded in 1970 and took advantage of CARB’s efforts to improve air quality in California. The EPA’s first foray into regulating combustion engine emissions was the Federal Clean Air Act.

CARB standards are required by law in only one state: California. Any engine manufactured or sold in the United States must meet EPA requirements. However, many other states have implemented CARB regulations far more stringent than the EPA’s.

New York, Rhode Island, Washington, Pennsylvania, Connecticut, Oregon, Vermont, Maryland, New Jersey, and Massachusetts require compliance with CARB’s more rigorous standards.

Why Is It Important To Be CARB Compliant?

Being carb compliant means that your equipment meets the current carb respectful limits set by CARB. It also means that you are producing less harmful emissions, toxins, and particulates into the air supply, which leads to a cleaner and safer environment for all Californians.

In addition, operating CARB-compliant machinery can result in increased efficiency. Finally, if you use a CARB-compliant business, you will also save money on fuel costs.

What Does CARB Affect?

Internal combustion engines are the most vulnerable types of engines to CARB.

It covers all engines that use combustible fuels, such as diesel, natural gas, or propane. The CARB rules and regulations apply to a wide range of heavy equipment and machinery.

CARB certificates are required for anything that runs on gasoline or diesel. It also includes generators (commercial and residential), cars, trucks, tractors, lawnmowers, chainsaws, pressure washers, and other vehicles equipped with an internal combustion engine that run on combustible fuel. It is due to the internal combustion engine’s emissions, particles, and hazardous gases.

Why Do I Need To Be CARB Compliant?

Suppose you operate equipment with internal combustion engines, such as boilers or turbines. In that case, you need to meet CARB compliance standards because it will result in cleaner air for Californians.

Although carb compliance may not seem like it affects you, CARB-compliant machinery is more efficient. As a result, many companies that operate CARB-compliant equipment can save money on fuel costs.

How To Become CARB Compliant?

Your equipment must meet the CARB-compliant emission limits set by CARB. However, suppose your kit does not currently meet these carb-compliant limits. In that case, there are various ways that you become carb compliant.

For example, some organizations can perform a CARB compliance audit on your business to determine what needs to be done for your equipment to meet CARB compliant standards.

Then they will implement the necessary changes. In addition, if you are looking for new machinery that is CARB compliant from the get-go, don’t forget to check the carb-restricted emission limits before you purchase.

CARB Compliant Engine vs. Non-CARB Compliant

A CARB-approved SORE has gone through the steps to obtain an Executive Order from the CARB certifying their engine family (families) as meeting its criteria.

A SORE that is “non-compliant with CARB” may meet CARB emission requirements. Still, they have not gone through the certification procedure to obtain the Executive Order from CARB, so they miss out on all of California’s sales.

What Is CARB Compliance For Generators?

CARB compliance is when your generator meets CARB compliant standards set by CARB. Meeting CARB-compliant standards is crucial because it helps produce cleaner air in California and more efficient machines that save fuel costs.

Why Is CARB Compliance Important For Generators? 

Carb compliance for generators is essential if you want your generator to be up-to-date with CARB compliant standards. Generators must have a CARB compliance kit installed and an air injection system.

How Does CARB Affect Generators?

The primary component is an internal combustion engine that burns fuel. Because carb compliant limits are stricter, carb compliance can increase fuel costs for generators that do not meet CARB compliant standards. However, because CARB-compliant machinery is more efficient, it will also save you money on your electricity bill.

For example, a generator with an efficiency rating of 80% at 50% load would only produce 100% – 20% = 80 kW. However, carb compliant machinery with an efficiency rating of 90% at 50% load would make 100%- (90/100)*50%= 44kw.

Wrap Up

Suppose your business is CARB compliant. Congratulations! Operating a CARB-compliant business has many benefits, including increasing efficiency and reduced fuel costs.
