In addition to investments in new technologies to support the energy transition, we’re committed to providing trucks that comply with stringent emissions regulations.
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:
Canada's Off-Road Compression Ignition Engine Regulations have the same emission limits as U.S. EPA.
*California Air Resources Board Tier 4 Final: Limited Model Availability
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.
