CDTi (NASDAQ: CDTI) is a cleantech emissions control company that designs, develops and manufactures sustainable solutions to reduce emissions of on- and off-road engine applications.

We are a leading global manufacturer and distributor of heavy duty diesel and light duty vehicle emissions control systems and products to major automakers and retrofitters.

Our business is driven by increasingly stringent global emission standards for internal combustion engines, which are major sources of a variety of harmful pollutants.

Air pollution can affect our health in many ways. Numerous scientific studies have linked air pollution to a variety of serious health problems for people, especially the young and elderly.

In response to human-health issues and air-quality concerns, 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.

Because standards put in place by the US Environmental Protection Agency (EPA), California Air Resources Board (CARB) and other international regulators continue to become more restrictive over time, we view the markets for our products as continually expanding.
