2. Method
This paper first evaluates the economic feasibility of each of six segments (from Jataí to Paulínia and Anhembi to
Paulínia) of the Logum pipeline system by applying the standard net present value method , as demonstrated in the
biofuel pipeline context in Strogen et al. [4]. We exclude the segment from Barueri to Santos due to a lack of available
information. The remaining segments in the configuration are existing oil pipelines and are also omitted from the
analysis. We then use the framework of Strogen et al. to estimate the life-cycle GHG emissions as a result of the
construction and use of each pipeline segment.
2.1. Data Sources
We retain several parameters from Strogen et al. [4], namely the fraction of construction costs assumed to be spent
on annual maintenance, pipeline utilization rate, fuel properties, and the GHG intensity of trucking freight. Most other
important parameters are taken from Logum [7] or other official documents; however, when unavailable from these
sources, parameters are taken from press reporting, estimated using a model, or assumed. Parameters common to all six
segments are presented in Table 1. Parameters specific to each pipeline segment are reported in Table 2.
