Mobile and Stationary Emissions Control

Our emission control catalysts and technologies reduce the impact of emissions from a variety of sources, including:

  • Gasoline and diesel powered cars and light vehicles.
  • Heavy duty diesel vehicles such as trucks and buses.
  • Non-road vehicles such as construction and agricultural equipment.
  • Vehicles powered by gas (LPG, LNG).
  • Stationary sources such as coal fired power stations, gas turbines, industrial plants, chemical processes, locomotive, marine and waste-to-energy industries.

Catalysts and technologies for these sources are supplied by Johnson Matthey's Emission Control Technologies business.
