[...] Vessel dockside emissions estimates were revised for the original 13 ports included in the 2008 inventory by updating the vessel daily fuel usage rates and emission factors, with the revised daily fuel usage rates linked to the vessel-days-at-port data provided by Semarnat. [...] The emission factors used to estimate emissions were compared to a set of residual fuel emission factors recently developed for the GREET model, as shown in Table 7. Note the GREET residual fuel emission factors were developed assuming a sulfur concentration of 27,000 ppm and fuel consumption rate of 195 g/kw-hr. [...] E = 102.3 / 1,000 x 87.62256 E = 8.96 kg Pollutant-specific comparisons of the emissions from the original Mexican Inventory and the updated emissions using the GREET factors are presented for individual ports in Table 8. Commission for Environmental Cooperation. [...] To approximate the emissions in the new ports, the revised emission values for the original 13 ports were divided by each port’s 2008 cargo tonnage to develop emission factors in metric tons of pollutant divided by cargo tonnage handled.
