The Clean Diesel Initiative was formed to work with fleet owners and operators to offer ways they can take advantage of the benefits of diesel engines, while reducing their impact. Fleets get help choosing the right mix of strategies for their business and in some cases, the fuel savings pays for the strategy, especially when combined with tax credits (and grants when available). Strategies for reducing diesel exhaust are categorized under three primary approaches: burning less fuel, burning cleaner fuel and burning fuel cleaner.
