Why are you addressing dairy cows?
Our product is good for all farm animal. But to qualify as Carbon Project, we have to comply with a protocol. These protocols are limited in number. For the time being, only dairy cows are subject to a Carbon Credit Project Protocol. Which make sense as they are the main producer of methane gas, one of the main driver of climate change.
What animal produces the most methane?
Average per animal, per year, in kg:

While carbon dioxide (CO2) is typically painted as the bad boy of greenhouse gases, methane (CH4) is roughly 30 times more potent as a heat-trapping gas. So, the climate impact of 1kg of methane is equivalent to 30kg of CO2.
In the rumen (stomach) of a cow, one find the following gases:
Hydrogen 0.2%, Oxygen 0.5%, Nitrogen 7.0% Methane 26.8% Carbon dioxide 65.5%
