Energy use emission factors for livestock production.

Source: R/livestock_coefs.R
gleam_energy_use_ef.Rd

Emission factors for embedded (feed-production) and direct (on-farm) energy use in livestock production, from GLEAM 3.0 tables S.7.1 through S.7.7. Note that the factors are expressed per kilogram of live weight, milk or egg depending on the species and herd: see the denominator column. The GLEAM footnotes are materialised as derived rows: embedded energy for meat (non-dairy) cattle and all buffalo is half of dairy cattle (S.7.1 note a); embedded energy for non-dairy small ruminants is half of the listed values (S.7.2 note a); direct energy for dairy small ruminants is double the dairy cattle values (S.7.5 note a).

Usage

gleam_energy_use_ef

Format

A tibble in long format with columns:

species

Animal species or group ("cattle", "buffalo", "large_ruminants", "small_ruminants", "pigs", "chickens").

herd

Herd or product line ("dairy", "non_dairy", "broilers", "layers", "all"). NA for pigs.

grouping

Country or country group as reported by GLEAM (e.g. "OECD", "EU 27", "Least developed countries").

grouping_scheme

Which country grouping the grouping belongs to: "development3" (OECD / least developed / others), "region5" (OECD / four non-OECD regions) or "detailed15" (individual OECD members plus world regions).

system

Production system (e.g. "grassland_based", "industrial"). NA when not applicable.

climate

Climate zone ("arid", "humid", "temperate"). NA when not applicable.

energy_type

"embedded" or "direct".

denominator

Reporting basis of the factor: "lw" (live weight), "milk" or "egg".

emission_factor

Emission factor in kg CO2-eq per kg of the denominator.
