By initiating the Clean Fleet Vehicle Ordinance in March of 2006, the
City of Coppell has reduced fuel consumption and emission, notably
nitrogen oxide (NOx).  According to the Clean Fleet Vehicle Ordinance,
the Fleet Services Division maintains over 130 city vehicles while abiding
by the Clean Fleet Vehicle Ordinance which mandates routine maintenance,
regular safety and emission inspections, and other actions such as
educating drivers on driving habits and correct tire pressures.  The
ordinance also includes a strict no-idling policy, and requires the
purchases of vehicles with reduced emissions.  

Thirteen percent of the City of Coppell fleet are now hybrid electric vehicles with the first purchase of the Toyota Prius, and later adding the hybrid Honda Civics and hybrid Ford Escapes.   

The new fire apparatus comply with the new stricter EPA 2010 Heavy-Duty Diesel Emission requirements.
