Transportation creates nearly a quarter of all energy-related carbon emissions, and because of this, a key strategy in stabilizing the climate is to greatly expand low-carbon fuels. BSR’s Future of Fuels initiative helps companies understand the impacts of transportation fuel and how they can work together to create a system that is sustainable, resilient, and affordable.

In 2015, we developed a Fuel Sustainability Tool (Fuel Tool) with our member fleet owners and their value-chain partners so they can quickly assess the impacts of fuel for trucking to identify low-cost, sustainable, and scalable solutions. It allows decision-makers to compare fuel pathways within types of fuels used in medium- and heavy-duty trucks in North America.

This report provides technical references for the Fuel Tool. BSR developed the tool with user input from a steering committee of fleet operators and technical input from a technical working group of experts in fuel and vehicle sustainability. Version 1.0 of the tool uses the best available carbon-intensity modeling based on Argonne National Laboratory’s GREET model, with results for several fuel types from the California Air Resources Board’s California-GREET and the Oil-Climate Index (OCI), and select scenarios from EDF. Qualitative data on social, environmental, and best practices considerations are drawn from research summarized in BSR’s “Future of Fuels Sustainability Briefs,” supplemented with input from the technical working group.

The document references version 1.0 of the tool. We are currently developing version 1.1, which we expect to complete by the spring of 2016.
