cowfootR

Dairy Farms emitting CO2

Manure

Mudanjiang Mega Dairy Farm (China)

100,000 to 150,000 cows

Common Sources of Greenhouse Gases (U.S.)

Agriculture causes significant CO2 levels (2024)

Usage of cowfootR (for a singular farm)

• Step 1 (Input): Determine what the farm will look like (number of cows, production of milk, utilization of land/energy, etc.)
• Step 2 (Calculation): Use IPCC/IDF math to turn that information into kg of \(CO_{2}e\).
• Step 3 (Visualization): Take the calculated results and utilize ggplot2 to draw charts.

What are the details of the farm?

• What are the boundaries of your study?
  • Farm-gate
  • Cradle-to-farm-gate
• What is the raw data from farm records?
  • Herd
  • Production
  • Land/Energy

What contributes the most amount of greenhouse gases?

• IPCC/IDF Formulas
  • The package takes the farm data given and uses scientific formulas to estimate gas-specific emissions.
• The Four Functions
  • calc_emissions_enteric() (Methane)
  • calc_emissions_manure() (Methane & Nitrous Oxide)
  • calc_emission_soil() (Nitrous Oxide)
  • calc_emissions_energy() (Carbon Dioxide)

Most to least impactful emissions

A different way to perceive emissions

How efficient/intense is the farm?

• Total Footprint: 15760 Tonnes
• Milk Intensity: 3.014 kg/kg FPCM
• Area Intensity: 262660 kg/ha

What if an emission reduction strategy was used?
