Feb 01, 2021 Keith Wilson, president of Titan Freight Systems, is working with Oregon legislators to draft a bill that would phase out sales of petroleum diesel, starting in 2023, and increase the supply of renewable fuels. Titan Freight Systems in 2010 set an ambitious goal to reduce fleet emissions by 20% within a decade. The Portland, Oregon-based company’s Vision 2020 plan had metrics tied to fuel efficiency gains. To execute on those metrics, Titan replaced most of the 2007 EPA Tier 2 and older engine emission trucks in its fleet and invested hundreds of thousands in aftermarket products that included engine idle shut off devices, cab fairings, trailer side skirts, wheel covers and technology for monitoring driver speeds and behaviors.
