Solutions to Reduce Regulated Criteria Pollutants
In addition to investments in new technologies to support the energy transition, we’re committed to providing trucks that comply with stringent emissions regulations.
U.S. EPA & CARB*
TIER 4 FINAL AND EU STAGE V
Caterpillar provides U.S. Environmental Protection Agency (EPA) Tier 4 Final, European Union (EU) Stage V or equivalent products in North America, Europe and select regions around the world. Product improvements in each segment provide customers with cost-saving benefits of improved fuel efficiency and fuel flexibility.
While Tier 4 Final and Stage V regulations are different, Cat mining trucks employ a common hardware solution to meet both. Every engine is equipped with a combination of proven electronic, fuel, air and aftertreatment components, based on engine size, application and the geographic location in which it will work.
U.S. EPA regulations define specific limits for:
- Particulate matter (PM)
- Non-methane hydrocarbons (NMHC)
- Nitrogen oxides (NOx)
- Carbon monoxide (CO)
Canada's Off-Road Compression Ignition Engine Regulations have the same emission limits as U.S. EPA.

FUEL OPTIMIZED / U.S. EPA TIER 2 EQUIVALENT
Fuel optimized / U.S. EPA Tier 2 equivalent engines have lower particulate matter (PM), hydrocarbons (HC), nitrogen oxides (NOx) and carbon monoxide (CO) in comparison to U. S. EPA Tier 1 and non-regulated engines. This improves mine site air quality.
NOTE: Continuous support is available for in-service machines.
