Reliable Performance. Environmental Responsibility.

At Kubota Engine America, emissions compliance is a core part of how our engines are designed, tested, and supported. We take a proactive approach to meeting global emissions regulations while continuing to deliver the durability and reliability our customers expect.

Kubota Quality Inspection Facility

Kubota’s commitment to emissions compliance and quality begins with a dedicated global focus. The Engine Environmental Management & Promotion Department (EEMPD), based in Osaka, Japan, monitors emissions regulations worldwide, evaluates evolving requirements, and shares critical insights across the organization to ensure alignment at every stage of engine development.

Kubota Corporation’s quality inspection facilities are designed to meet some of the world’s most stringent emissions requirements. Through comprehensive, automated emissions testing, newly developed engine models must pass certification testing for all applicable regulations before entering mass production.

Once in production, ongoing sampling inspections help verify continued compliance and reinforce Kubota’s reputation for quality, reliability, and long-term regulatory readiness.

What Is an Emissions Certificate?

An emissions certificate verifies that a specific engine family conforms to required emissions regulations for a given model year and power category. Emissions certificates are typically used by OEMs, regulators, and distributors for documentation and compliance purposes.

If you need a copy of your engine’s emissions certificate or emissions warranty information, you can request it using our online form.

Engine Emissions Labels

While emissions certificates exist at a regulatory level, most users only need to locate and read the emissions label on the engine itself.

The emissions label displays the key information required to confirm regulatory compliance, including:

  • Engine family designation
  • Emissions tier or standard
  • Applicable regulatory statements

Locating The Emissions Label on Your Engine

  1. In order to ensure that the certificate matches the engine, first locate the Emissions Label on the engine. The label is located on the valve cover of the engine, and has important emissions information.
  2. The label heading describes what emissions standards the engine is certified to meet.
  3. The family name is used by regulating agencies to identify certified engines. This family name is the best way to look up the appropriate emissions certificate.
  4. The first character of the family name represents the model year of the engine
  5. The EPA and CARB websites disclose detailed emissions certification information
