Emissions

The California Air Resources Board (CARB) has been implementing significant regulations that mandate the lowest emitting non-road equipment. These regulations, commonly known as Tier 4, will result in non-road equipment approaching near-zero emissions of particulate matter and oxides of nitrogen.

These standards present numerous challenges for equipment manufacturers. For Caterpillar alone, hundreds of products with unique and challenging application opportunities must be re-engineered or re-designed to accommodate the lower emitting engines being developed to meet or exceed these standards.

Caterpillar has a robust Tier 4 introduction plan, which will allow a transition from Tier 3 to Tier 4 products. The goal is to maximize value to you, our end-users.

Caterpillar's "Tier 4 Interim Operator Interface" video provides emissions regulations and Tier 4 operator tips.

Each industry has some different opportunities.
