Emission control systems, developed by Johnson Matthey (JM) and its partners, have been installed in over 1,000 London buses, enabling them to meet increasingly stringent emissions targets.
The technology complements our longstanding work to reduce harmful emissions to make our environment cleaner and healthier.
Making the Old New
Through the use of catalyst and filter systems, JM and its partners are able to take a twelve-year-old bus and achieve emissions comparable to those from a modern bus. Approximately fifteen older buses can be retrofitted for the cost of a brand new model, conserving natural resources, reducing fleet costs and minimising environmental impact.
Meeting the Latest Legislation Standards
Johnson Matthey scientists are working on new advanced catalysts that could enable 5,000 London buses to meet the latest clean air threshold defined by EU regulations, known as Euro VI. London has a stated objective of achieving an ultra-low emission zone at its heart by 2019 and Johnson Matthey and its partners have demonstrated that the latest technology is certainly capable of meeting this high standard. Emission control systems in London buses acts as a new component in Johnson Matthey's Clean Air sector, with one third of new vehicles worldwide containing our catalysts, preventing 40 tonnes of potentially harmful emissions from entering and polluting the atmosphere every minute.
