Thornton has dramatically increased the number of hybrid vehicles in its fleet in recent years, effectively doubling fuel economy, reducing maintenance requirements, and improving vehicle reliability.
- All new diesel vehicles are now using tier 4 emissions technology, which reduces emissions to nearly zero.
- Vehicles which have traditionally required a high level of maintenance, repair, and service are being phased out and replaced with improved models.
- The majority of Thornton's equipment is now on a 10 year replacement cycle, which is a doubling of the 5 year cycle that much of it was on in earlier years.
- Vehicle tires are chosen to provide longer service life and improved vehicle fuel economy.
- All forklifts are now powered by propane.
- Thornton is in the process of exploring the possibility of moving toward all electric vehicles.
- Thornton shares gasoline and diesel pumps, propane, vehicle wash facilities, and salt & sand storage with the Adams 12 School District.
