This week’s guest is Dr. Alex Scott, Associate Professor of SCM at UTK and co-founder of Sustainable Logistics. There is growing pressure on companies - both regulatory and socially - to reduce the emissions that they generate. One of the largest sources of CO2 emissions is freight transportation. Unfortunately, most companies outsource their transportation to carriers - so they do not have direct control over the asset being used. These types of emissions - where the company is responsible for it but does not have direct control over the asset - are referred to as scope 3. They are the hardest type of emissions to measure.  In our conversation, Alex describes how Scope 3 emissions are currently being measured today, discusses the regulatory trends in emissions monitoring, and explains the trade-offs between reporting accuracy and cost of collection. Through his research and now his company, Sustainable Logistics, Alex has developed a better approach that improves the accuracy of the measurement of Scope 3 emissions from truck transportation. This is an issue that is only going to become more critical for all transportation executives, so I encourage everyone to take a listen.
