About Mobile Emissions Catalysts

Arguably the most important pollution abatement device ever invented, the catalytic converter is a key component of most new car engines in the world today. Without them, air quality in and around most cities would be far worse than it is today.

BASF pioneered the development of the first catalytic converters on 1975-model cars, and one year later introduced a second major innovation: the modern, “three-way” catalyst, which is now capable of destroying over 90% of hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOx) produced by car engines.

Since its inception, BASF’s three-way catalyst technology has destroyed over 1 billion tons of HC and NOx and CO before they ever reached the atmosphere.

BASF continues to lead the way in the development and commercialization of advanced emissions catalysts for both gasoline and diesel-powered vehicles. 

BASF works closely with our automotive customers to adapt leading-edge technologies to meet their needs for high performance and cost, and helps them to comply with tighter environmental regulations around the world.

The focus of the BASF Emissions Professional is always on innovative, cost-effective solutions to meet the needs of customers. With a creative, open, responsible and entrepreneurial approach we help make our customer more successful. That’s the EMPRO ™ Way.
