Engine Off North Texas

Engine Off North Texas (EONT) is a regional initiative dedicated to reducing the impacts associated with the unnecessary idling of vehicles. Efforts are focused on expanding the adoption of anti-idling ordinances, implementing policies for fleets, providing idle reduction technology options, and promoting various idle reduction strategies across the region.

yellow-semiHeavy-duty diesel trucks contribute to 48% of on-road mobile source ozone causing emissions in the North Central Texas region.  Reducing unnecessary idling can help decrease these emissions and provide better air quality for everyone.  NCTCOG wants to help the trucking industry and heavy-duty diesel drivers do their part in improving the environment by providing:

- Information about local anti-idling ordinances within the region
​- Locations of electrified parking spaces
- Idle reduction strategies and available funding information
​- Fleet policy solutions


Local governments play a major part in improving air quality for the north central Texas region by adopting and enforcing ordinances and implementing policies that encourage heavy-duty diesel vehicle idle reduction.  NCTCOG has developed several resources available to local governments which includes;

- Potential Enforcement Strategies
- Guidance for Local Governments 
- Clean Fleet Policy 
- TCEQ Idling Limitations Rule Updates
- Idle Free School Zones
