Extraction-Based Environmental Loadings

This guide explains the 'Extraction-Based Environmental Loadings' methodology in LEAP, an optional alternative to the standard territorial approach for accounting for emissions based on where resources are produced rather than where they are combusted.

• LEAP's standard environmental loading calculations follow the territorial approach used by countries for UNFCCC reporting and IPCC guidelines, which attributes emissions to the location where fuel is combusted. For instance, coal mined in one area but burned in another is accounted for in the location of combustion.
• Extraction-based environmental loadings provide an alternative method that allocates emissions to the area producing the emissions. This comparison helps illustrate a country's dependence on fossil fuel production and its vulnerability to a global transition toward low carbon economies.
• Extraction-based loadings are configured by entering emission factors under the Resources\Primary branches in the LEAP tree. Users can manually enter factors, use mathematical formulae, or link to the Technology and Environment Database (TED), where factors for SO2 and CO2 are often functions of sulfur and carbon content, respectively.
