Emission Factor Library

Emission factors are organized as a single record of data for each relevant greenhouse gas.

Usage

EFLibrary

A data frame with 33,421 rows and 18 columns:

ef_source: Emission factor source.
ef_publishdate: Emission factor publication date.
ef_activeyear: Year for which the emission factor is active for GHG reporting.
service_type: Name for the fuel or activity which generates emissions. Must match servicd type in activity data.
unit: Unit for which the service type activity data is provided.
emission_category: Category of emissions, e.g., mobile, stationary, and indirect energy.
service_subcategory1: Optional input. If used, must match a service_subcategory1 in activity date
service_subcategory2: Optional input. If used, must match a service_subcategory2 in activity date
supplier: Optional input. Supplier of the service type.
emission_scope: Scope of emissions, i.e., scope 1, 2, or 3.
country: Used to specify a country for the emission factor.
subregion: Used to specify a sub-region for electricity emission factors.
ghg: The greenhouse gas procued by the service type.
ghg_unit: The greenhous egas unit. This matches the unit provided in the emission factor source documentation.
source_emission_factor: The emission factor in source units.
unit_conversion: ghgtools requires emission factors are in kg of ghgs. The ghg_unit must be converted to kg using a unit conversion.
conversion_factor: ghg unit conversion factor.
ghg_perunit: Emission factor in kg ghg per service type unit.
