In 2020, our company-owned fleet accounted for nearly 30 percent of our global Scope 1 and 2 emissions. In 2020, this global fleet traveled nearly 1.3 billion miles and consumed approximately 5.3 million megawatt hours of fuel, of which nearly 1.4 percent was from renewable sources.
In 2020, we continued to optimize and right-size our PepsiCo Beverages North America (PBNA) delivery vehicles by reducing the weight of the tractor and trailer specification to help us transport more product without increasing miles. PBNA is also accelerating deployment of its Geo Box delivery system, which replaces bay delivery trucks with specially designed trailers that are pre-loaded at the warehouse. This ensures the right quantity and assortment of product reaches our retail customer in a more efficient and timely manner, and reduces the number of fleet assets needed on the road, reduces fuel use through optimized loads and routes, resulting in fewer miles driven.
PepsiCo Foods North America (PFNA) introduced tractors with liftable tandem axles which deploy or lift the second axle as required by the weight of the load, resulting in reduced rolling resistance, reduced tire and brake wear and improved MPG by over 4 percent. We also purchased more than 850 30’ box trucks which have 25 percent more cargo volume and a 9 percent improvement in fuel economy when compared to the 24’ box trucks they are replacing. This, combined with our approximately 215 additional drop frame trailers that maximize available trailer volume, reduce the total number of miles required to deliver the same amount of product.
We also invest in energy saving technology and advanced aerodynamic devices, use low rolling resistance tires, reduce weight, and improve powertrain efficiency in our new equipment.
We continue to make improvements in fleet efficiency through Advanced Driver Assist Systems (ADAS), more efficient routing, and driver training that encourages fuel conservation. Training encourages gentler acceleration and emphasize the importance of unnecessary braking and reduced idling. Safety features like collision mitigation, adaptive cruise control, blind spot monitoring, and lane keep assist are being deployed to keep our drivers and communities safer while improving efficiency.
Cleaner Fuel Sources
Our PFNA class 8 tractor fleet is comprised of 48 percent Compressed Natural Gas (CNG) vehicles, and in 2020, the CNG fleet drove over 64 million miles. We continue to increase the use of natural gas sourced from renewable sources, achieving 75 percent renewable fuel in 2020, and we have established fueling contracts to ensure that all future fleet natural gas will be from renewable sources. Operating CNG tractors in 2020 resulted in 62,000 metric tons of GHG reduction.
At our Frito-Lay manufacturing site in Modesto, California, the implementation of zero-emission and near zero-emission technologies over the past year has reduced the site's fleet absolute GHG emissions by more than half (53 percent), or nearly 2,800 metric tons of absolute GHG emissions, and has lowered fleet diesel usage by nearly 80 percent. To date, the equipment and infrastructure in place at the site includes nearly 60 tractors, box trucks, yard trucks, or forklifts powered by electric, lithium-ion technologies or natural gas with renewable attributes. Additionally,15 Tesla semi tractors are expected to deploy by the end of 2021. Infrastructure to support the project incorporates an adjacent natural gas station with renewable attributes, as well as solar carports, battery storage, truck charging systems, and employee electric vehicle charging stations.
In our effort to continuously explore emerging technologies that will position us for the future, we made an initial reservation for 100 all-electric class 8 tractors from Tesla. These will be deployed across both our snacks and beverage businesses to evaluate how best to leverage electric vehicles and technologies moving forward.
We believe it is important to engage in and support multi-stakeholder alternative energy initiatives. We are an original signatory of the Sustainable Fuel Buyers’ Principles. These Principles, developed by the non-governmental organization Business for Social Responsibility (BSR), encourage accelerating the transition to sustainable, low-carbon fuel and related technologies.
