In order to meet our target for carbon reduction in our U.S. sales fleet and reduce fuel use, we set standards for the average fuel efficiency of fleet vehicles that we introduce into the fleet each year. When we integrate more fuel-efficient vehicles, the overall average fuel efficiency of the fleet is improved, helping us to achieve our carbon reduction target.
During 2015, we coordinated with our suppliers to set the minimum requirements for the fuel efficiency of 2016 model year fleet vehicles to 26 miles per gallon (MPG) in our U.S.-based sales fleet. We purchased vehicles with that standard in both late 2015 and into 2016. During 2016, we set a new standard to purchase 2017 model year vehicles that achieve an overall average of 27 MPG and purchased vehicles with that standard in both late 2016 and into 2017. We achieved an average performance of 26 MPG for our U.S. sales fleet vehicles in 2016 (see the Performance section for more information).
To manage our U.S. sales fleet vehicles, we partner with an outside vendor that offers a range of tools to track vehicle performance and fuel efficiency. Additionally, we coach staff members to drive in more fuel-efficient ways.
