On a farm, most of the carbon comes from livestock and fertiliser
On a farm, most of the carbon never comes out of a tailpipe. It comes from the herd and from the nitrogen you put on the ground, both of which are modelled rather than read off a meter. The analyst works them out on the NGER method, alongside the diesel and electricity that are easier to measure.
You stay the reviewer
Farm records in, a defensible on-farm number out
The inputs are the ordinary records of the farm: fertiliser invoices, head counts, fuel deliveries and power bills. The analyst takes what you have, applies the NGER method and the right default factors, and gives you an on-farm number you can stand behind when a buyer or an assurer asks how it was built.

How it works
Drop in fertiliser invoices, head counts, fuel and electricity records, the analyst calculates each scope with matched factors, and you report per enterprise, per paddock or consolidated across the operation.

Enteric methane
For most grazing enterprises, enteric fermentation is the single biggest line. CO2 Lab applies the NGER livestock method to your head counts by class, converts methane at a global warming potential of 28, and reports it as a modelled number, because that is what it is.

Scope 1 · Soil
Fertiliser nitrous oxide
Nitrogen you apply turns into nitrous oxide in the soil, a gas 265 times stronger than carbon dioxide. CO2 Lab takes the applied nitrogen off your fertiliser invoices, applies the IPCC default emission factor, and flags the line as modelled, so your on-farm Scope 1 is honest about what is estimated.
Scope 1 & 2 · Energy
Fuel and electricity
Diesel for machinery and irrigation pumps, and grid electricity for sheds and cold stores, are the metered part of the footprint. CO2 Lab reads fuel deliveries and power bills, applies the current NGA factors, and sits them alongside the modelled biological lines so the whole picture reconciles.
