What this number covers

The path of one kilogram of waste from your bin to the treatment site. Every step on it is counted; NAEI publishes the route as one number, not step by step.

Treatment
Treating the waste on the route it is sent down
Included2.97
Your waste
1 kg sent for treatment, weighed as you hand it over.

Gases

Basis: Excl. biogenic CO₂FossilBio CH₄Land useBio CO₂GHG Protocol and IPCC inventories

Carbon dioxide (CO₂)2.7592.5%
Methane (CH₄)0.1816.1%
Nitrous oxide (N₂O)0.04091.4%

Σ 2.75 + 0.181 + 0.0409 = 2.97.

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.
