AECC is an international non-profit scientific association of European companies engaged in the development, production and testing of catalyst and filter-based technologies for vehicle and engine emissions control. This includes the research, development, testing and manufacture of catalysts, ceramic substrates and specialty materials incorporated into the catalytic converter and filter and catalyst-based technologies to control internal combustion engine emissions (especially particulates and nitrogen oxides). Members’ technology is incorporated in the exhaust emission control systems on all new cars, commercial vehicles, buses, non-road mobile machinery and motorcycles in Europe.
