The United States and European Union are implementing significant regulations that mandate the lowest emitting non-road equipment in history. These regulations, which are known in the United States as Tier 4, will result in non-road equipment approaching near-zero emissions of particulate matter and oxides of nitrogen.

Transition to these standards is challenging for non-road equipment manufacturers. For Caterpillar alone, hundreds of complex products with unique and challenging application spectrums must be re-engineered to accommodate the lower emitting engines being developed to meet these standards.

Caterpillar has a robust Tier 4 introduction plan, which is structured to transition from Tier 3 to Tier 4 products in a smooth and orderly fashion utilizing a variety of the transitional tools provided in the regulations in order to maximize value to our dealers and end-users.
