IPCC 2019 enteric EF for non-cattle.

Tier 1 enteric fermentation emission factors for non-cattle species (kg CH4/head/yr). Non-cattle species are Table 10.10 in both the 2006 Guidelines and the 2019 Refinement; regional cattle factors are Table 10.11 (see ipcc_2019_enteric_ef_cattle).

Usage

Format

A tibble with category, ef_kg_head_yr.

Source

The 2006 Guidelines, Vol 4, Ch 10, Table 10.10, developed-countries column (buffalo 55, sheep 8, goats 5, camels 46, horses 18, mules and asses 10, swine 1.5), not the 2019 Refinement. The Refinement's Table 10.10 (Updated) splits every ruminant and swine factor by productivity system (sheep 9 high / 5 low, goats 9 / 5, swine 1.5 / 1.0), leaves camels, horses and mules unchanged, and moves buffalo out of this table into the regional Table 10.11. Poultry is stored as 0; both editions say "insufficient data for calculation", so the zero is a project choice rather than a published factor. Tracked in whep#601.
