18 dairy cows and 20 other cattle are in a farm. find the CFP of this animals due to enteric fermentation

To calculate the Carbon Footprint (CFP) of the animals due to enteric fermentation, we need to know the amount of methane (CH4) each type of animal produces per year and the Global Warming Potential (GWP) of methane.

1. According to the IPCC (Intergovernmental Panel on Climate Change), a dairy cow produces about 110 kg of CH4 per year and other cattle produce about 53 kg of CH4 per year.

2. The GWP of methane is 25, which means methane is 25 times more potent as a greenhouse gas than carbon dioxide (CO2).

3. Calculate the total amount of CH4 produced by the dairy cows and other cattle:

   For dairy cows: 18 dairy cows * 110 kg CH4/dairy cow = 1980 kg CH4

   For other cattle: 20 other cattle * 53 kg CH4/other cattle = 1060 kg CH4

4. Add the total amount of CH4 produced by the dairy cows and other cattle: 1980 kg CH4 + 1060 kg CH4 = 3040 kg CH4

5. Convert the total amount of CH4 to CO2 equivalents (CO2e) by multiplying by the GWP of methane: 3040 kg CH4 * 25 = 76000 kg CO2e

So, the Carbon Footprint (CFP) of the 18 dairy cows and 20 other cattle due to enteric fermentation is 76000 kg CO2e per year.
