NewWorld Capital Group has acquired Cleaire Advanced Emission Controls, which provides emissions retrofit equipment for heavy-duty diesel vehicles.


Cleaire's products are verified by the California Air Resources Board at Level 3, a Best Available Control Technology abatement standard. The company's products reduce particulate matter emissions from in-use diesel engines by greater than 85%. Cleaire is headquartered in San Leandro, Calif., with a manufacturing facility in San Diego,

NewWorld Capital Group is a leading private equity firm focused on investing in the rapidly growing environmental opportunities sector, principally in the United States.

In light of rapidly growing demand for mobile-source diesel particulate filters, NewWorld's investment will enable Cleaire to expand its sales and product support capability in domestic and international markets.

"We are delighted to have NewWorld Capital as the next owner of our company," said Cleaire's founder Kevin Shanahan. "Cleaire is confronting a major opportunity as demand for reducing diesel particulate emissions surges in California and elsewhere around the U.S."
