Fleet sustainability has evolved beyond corporate buzzwords into meaningful emission reduction strategies that benefit both organizations and the environment. A comprehensive emissions-reduction plan includes multiple elements: eliminating unnecessary idling, strategically deploying electric or alternative fuel vehicles, promoting fuel-efficient driving techniques, utilizing renewable diesel as a bridge technology, and spec'ing vehicles for optimal efficiency. Fleet operators can achieve significant cost savings while meeting ESG sustainability goals through telematics systems, driver training programs, and newer emission reduction technologies, with 46% of surveyed fleets already implementing emission reduction programs.
