The factor, standardised
Every factor on open-climate.ai answers the same questions in the same words, whatever the publisher. Open any ⓘ for the definition.

- CO₂e basisWhich carbon the CO₂e counts. Fossil only leaves out biogenic methane, land-use change and biogenic CO₂; excl. biogenic CO₂ counts biogenic methane but not the other two; net total counts every pool, net of removals. The same activity on two bases is two different numbers. Learn more

ERASM does not count any of this in the figure for 1 kg active substance.
Gases
Basis: Excl. biogenic CO₂Biogenic CO₂ and land-use change are left out; fossil CO₂, the other greenhouse gases and methane from biogenic sources are counted. Learn moreFossilBio CH₄Land useBio CO₂GHG Protocol and IPCC inventories
- Fossil CO₂2.2189.8%
- Methane (CH₄)0.2299.3%
- Biogenic CO₂0.01120.5%
- Nitrous oxide (N₂O)0.01090.4%
Σ 2.21 + 0.229 + 0.0109 + 0.0112 = 2.46258, which ERASM rounds to 2.45.
Also printed, as zero: land-use CO₂.
Each gas is converted to CO₂e with AR6 100-year warming potentials; biogenic CO₂ and land-use carbon are left out, while methane from biogenic sources is counted.
