Regulations - Americas


Regulatory standards have been adopted worldwide to control the emissions of oxides of nitrogen (NOx), particulate matter (PM), carbon monoxide (CO) and carbon dioxide (CO2), from on- and off-road internal combustion engine exhaust.

We are committed to complying with all federal, state and international environmental laws governing production, use, transport and disposal of substances and control of emissions.

In addition to governing our manufacturing and other operations, these laws often impact the development of our emissions control products, including, but not limited to, required compliance with emissions standards applicable to new diesel, gasoline and alternative fuel engines.

These regulations include those developed in the United States by the Environmental Protection Agency (EPA) and California Air Resources Board (CARB) and other legislative bodies globally.

Many of our products must receive regulatory approval prior to sale. In the United States, regulatory approval is obtained from the EPA or CARB through a verification process.

The verification process includes a thorough technical review of the technology as well as tightly controlled testing to quantify statistically significant levels of emission reductions.

For example, the EPA verification process begins with a verification application and a test plan. Once this is completed, the testing phase begins and is then followed by a data analysis to determine if the technology qualifies for verification. Once a technology is placed on the verified technologies list and 500 units are sold, the manufacturer is responsible for conducting in-use testing and reporting of results to the EPA.

Similar product approval schemes exist in other countries around the world.
