The Manufacturers of Emission Controls Association (MECA) is a non-profit association incorporated in Washington, D.C. It was formed in 1976 to provide solid technical information on emission control technology for motor vehicles. As the emission control industry grew in the subsequent decades, and as its member companies expanded control technology products to other sources, MECA's mission expanded as well. Today, MECA's members include leading manufacturers of a variety of emission control equipment for: 1) automobiles, trucks, and buses; 2) off-road vehicles; and 3) stationary sources.

MECA members include manufacturers of...

For mobile sources:

• Catalytic converters (catalysts, substrates, mounting sleeves, and converter housings) for all fuels
• Diesel particulate filters
• Oxygen, NOx, and temperature sensors
• Thermal management strategies
• Engine/fuel management technologies
• Crankcase emission control technologies
• Evaporative emission controls
• Enhanced combustion technologies
• Plasma/corona technologies
• Components for fuel cell technology

For stationary sources:

• Selective catalytic reduction (SCR) systems
• Non-selective catalytic reduction (NSCR) systems
• Diesel particulate filters
• Catalytic oxidation systems

MECA's mission is to provide technical information on emission controls, thereby facilitating the establishment of a strong and effective state, national, and international air quality policy that promotes public health, environmental quality, and industrial progress. MECA strives to keep its members apprised of developments that affect the emission control industry so that they can make informed business decisions.

As the leading spokesperson for the motor vehicle emission control industry in North America, MECA seeks to evaluate and respond to regulatory initiatives and otherwise promote an understanding of the air quality benefits of its member companies' control technologies.
