FleetOwner: Counting carbon bears careful watching

A new report on this issue by ATRI – dubbed “The Synthesis of Carbon Accounting Tools” – involved the collection and analysis of carbon models and formulas, and interviews with environmental assessment and reporting organizations.
According to the report, there is a growing need for data and model standardization and identified areas where inconsistencies in the quantification tools and models exist.
“For many motor carriers, the U.S. EPA SmartWay Partnership truck model is the most widely recognized tool for quantifying greenhouse gas emissions,” said Tunnell. “This model calculates emissions generated from a company’s on-road vehicle fleet. However, an individual company’s carbon footprint encompasses more than just its on-road vehicle fleet.”
For example, quantifying the carbon emissions generated by office space and terminals, through metrics such as electricity use, could be misleading. “Although emission factors for the purchase of electricity are available for locations throughout the U.S., the greenhouse gas emissions generated from electricity purchased in one part of the country can be twice as high as the same amount of electricity purchased in another,” the report noted.
