Calculating maritime shipping emissions per traded commodity
This briefing describes a new data-driven methodology developed by the Stockholm Environment Institute (SEI) and University College London (UCL) to calculate maritime shipping emissions per traded commodity. By combining satellite-based automatic identification system (AIS) data with ship operational characteristics and shipping manifests, the approach allocates greenhouse gas and air pollutant emissions to specific commodities, exporters, importers, and traders. The method was piloted using 2014 Brazilian export data to demonstrate its ability to provide precise, transparent accounting for supply chain environmental footprints.

Checking Dust to Dust’s Assumptions about the Prius and the Hummer: Fact-checking using the GREET life cycle model underlines the deep divide between the Dust to Dust study and all previous scientific work
The Rocky Mountain Institute (RMI) conducted a fact-check of a report by CNW Research/Marketing titled 'Dust to Dust,' which claimed the Toyota Prius has a greater environmental impact than the Hummer H3 SUV. Using the GREET life cycle model developed by Argonne National Laboratories, RMI found that the Prius consistently has a lower environmental impact in terms of greenhouse gas emissions and energy consumption, even when manipulating variables to favor the Hummer.
