More and more countries are beginning to adhere to stricter emissions standards.  Fuel availability, a primary requirement for stricter emissions, sets the pace for these emissions regulations.

Cummins Emission Solutions uses advanced knowledge of aftertreatment system technologies to develop the right products and solutions for our customers.  We’re constantly working to better understand each country’s unique emissions standards and develop the right technology and solution for each market.

When it comes to mature emission regulations for commercial vehicles, the world is currently governed by three major legislative standards:

  • Environmental Protection Agency or EPA Standards
  • California Air Resources Board or CARB Standards
  • European Commission or Euro Standards
    • TA-Luft, Germany
    • Vehicle Certification Agency or VCA, United Kingdom
    • Japanese Ministry of Land, Infrastructure and Transportation or JMLIT Standards

In emerging emissions countries, there are also various governance sources that model their commercial vehicle regulations from the three major legislative standards of EPA, Euro and Japan standards:

  • China National Standard
  • India or Bharat Stage Standard
  • Brazil National Council for the Environment or CONAMA PROCONVE Standards
  • Korean Ministry of Environment or KMOE Standard 

On-Highway Regulations

Achieving on-highway emissions levels is a challenging yet attainable goal with the right solution in hand.  Since 2004, emissions requirements for both oxides of nitrogen (NOx) and particulate matter (PM) have reduced by 90% in mature markets.

With stricter regulations year after year, Cummins Emission Solutions is dedicated to helping our commercial vehicle customers meet the demands of regulatory agencies.  Our expertise in emissions research and development and our investment in critical technologies position us to be the technology leader in advanced exhaust aftertreatment solutions.

Off-Highway Regulations


Achieving off-highway emissions levels is an intense proposition.  It takes considerable technological resources, design expertise, manufacturing capability, testing capabilities, capital expenditures and the most limited resource of all – time.

By 2014, off-highway regulations in North America, Europe and Japan call for PM and NOx levels to be reduced by more than 90% from current levels for most power categories.  The use of advanced engine technology and exhaust aftertreatment is required to achieve these near-zero emissions levels in a broad range of off-highway applications.
