  1. Tier 4 Final Emission Standards

    Comments Off on Tier 4 Final Emission Standards

    You may have heard that this is the last year for Tier 4 standards to take effect. Tier 4 emission standards were first signed by the EPA in 2004 to help reduce fuel emissions from non-road diesel fuel engines, which can apply to construction equipment, agricultural equipment, and more.

    The standards began being phased-in in 2008 and 2015 is the last year, which means manufacturers should now be producing engines that meet Tier 4 standards. The final Tier 4 standards require that engines reduce emissions of greenhouse gases by 90%, specifically nitrogen oxide and particulate matter. Once the full inventory of older engines have been replaced by Tier 4 engines, annual emission reductions are expected to be at 738,000 tons for nitrogen oxide and 129,000 tons of particulate matter. These reductions will help improve the environment and reduce premature deaths.

    Some equipment manufacturers have already introduced the new engines into their equipment, such as Caterpillar and Cummins and we will continue to watch the industry for our readers.
