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.

This report by the Stockholm Environment Institute examines consumption-based emissions (CBEs) within the European Union, highlighting that the EU is a net importer of CO2 emissions. It analyzes the environmental footprint of EU household consumption, evaluates current policy frameworks, and provides detailed case studies of Sweden, Denmark, and France to identify barriers and opportunities for mitigating CBEs.
