# cowfootR Workflow

# Workflow overview

This vignette presents the overall workflow used by `cowfootR` to estimate dairy farm greenhouse gas (GHG) emissions. The flowchart below shows the main stages (data inputs, system boundaries, emission modules, aggregation, and reporting).

## What the diagram covers

- Inputs: Herd structure, milk production, feeds and purchased inputs, soils and manure management, energy, and other farm parameters.
- System boundaries: Definition of included and excluded processes for a consistent footprint (aligned with IPCC/IDF guidance).
- Emission modules: Enteric methane, manure, soils (N2O), energy, and indirect inputs.
- Aggregation: From module-level emissions to farm-level totals (CO2e).
- Intensity metrics: Emissions per litre FPCM and per hectare.
- Reporting: Batch and single-farm outputs, plus optional benchmarking.

## Reproducibility note

This is a documentation vignette. It does not run calculations itself; instead, it provides the conceptual map to help users navigate the package functions and data templates.
