Fitting an Eminox emissions reduction system to buses, trucks and other diesel powered vehicles already in service is the easiest, quickest and by far the most economical way to a clean fleet and solving transport related air pollution.
A retrofit approach to solving air pollution means you can clean-up the oldest, most polluting vehicles in the fleet and those vehicles operating in areas where air pollution is a problem, which means you can direct investment where it matters the most.
For the cost of a handful of new buses you can clean-up the whole fleet, as the following graph shows.

More than 50,000 vehicles have been retrofitted with an Eminox CRT® system in Europe alone, mostly to buses operating in busy city centres and urban areas where people live and work. Major fleets such as Tesco have fitted Eminox CRT®s as part of their environmental programmes and many local authorities have chosen the CRT® as their preferred particulate filter.
