Amazon is designing its upcoming fleet of electric vehicles to streamline delivery while eliminating emissions. In September 2019, Amazon initially announced that as part of its commitment to reducing carbon, it would order 100,000 electric delivery vehicles from sustainable vehicle manufacturer Rivian. This $440 million investment represents what Amazon says is the largest order ever of electric delivery vehicles, with vans starting to deliver packages to customers in 2021. In a new corporate blog post, Amazon is unveiling design details of the electric vans it says will enhance the safety and comfort of drivers while making deliveries more efficient and eliminating 4 million metric tons of carbon per year by 2030. Amazon's transportation team spent 18 months evaluating a variety of electric vehicle options to reduce its carbon footprint, and drivers who currently deliver Amazon packages had input into the vehicle's design and functionality.
