A refined approach to calculating scope 3 truck emissions has been developed, bridging the gap between direct tailpipe monitoring and simplistic single-factor estimations. This method estimates emissions based on specific carriers and their truck fleets, offering more accurate insights into emissions profiles. Here are three key points:
-
Carrier Emissions Profiles: Over half of carriers on the road have emissions rates greater than 1.7 kgs of CO2 per mile, while 7.5% operate fleets averaging less than 1.5 kgs of CO2 per mile, classified as "best in class."
-
Accuracy of Carrier-Level Estimations: Carrier emissions factors deviate only 4.2% on average from truck-level emissions factors, reducing error by about 72% compared to using a single emissions factor.
-
Implementation and Incentives: Calculating emissions at the carrier level incentivizes shippers to choose cleaner carriers, potentially reducing CO2 emissions by millions of kgs per year. Moreover, data on carrier emissions profiles is readily available and easy to implement.
In conclusion, this method offers several advantages, including accuracy, simplicity, and the ability to empower shippers to make more sustainable choices in their supply chains while reducing the risk of greenwashing.
