This is Part I of a two-part series exploring a “market-based” accounting and reporting approach to transportation decarbonization based on credible and flexible chain of custody practice. This Part I explores the common ways a “Mass Balance” chain of custody model is used in the transportation value chain—and its associated emissions reporting. Part II explores “Book and Claim” and how to “B.Y.O.” (bring-your-own) SAF and apply its profile to your logistics supply chain and reporting.
In order to jumpstart voluntary investment in transportation decarbonization, experts have encouraged enabling a “market-based” approach to low emission transportation procurement and corresponding accounting and reporting (see our blog on advocating for credible flexibility). In addition to regulatory measures, the market is capable of supporting “voluntary” measures that encourage greater supply of low emission fuel solutions and services. Demand is growing, supply is lagging, and many agree that such a flexible, market-enabling approach is necessary to kickstart the market. (....)
