• Produces less CO, VOCs, NOX and PM than gasoline or diesel,equates to 23 - 25% less GHG emissions
• Simpler solution amid forever tightening EPA requirements
• Non hazardous, will not pollute the ground or water
• 15% quieter than diesel trucks (happier drivers, customers, andneighbors)
• For RNG the decomposed waste can be traced back to the organicsource that replenished it; leads to even higher GHG emissionreductions over carbon life cycle

• Chassis cost is equal
• CNG time fill fueling station costs $695k to $990k
• Federal and some state grant money available.
