Calculate baseline methane emissions for compostable waste

Equation (1) of AMS-III.F multiplies waste quantities, degradable organic carbon parameters, and methane correction factors to estimate baseline methane emissions that would occur in unmanaged disposal sites.

  data,
  waste_quantity_col = "waste_tonnes",
  doc_fraction_col = "doc_fraction",
  docf_col = "docf_fraction",
  methane_correction_factor_col = "baseline_mcf_fraction",
  methane_fraction = 0.5,
  oxidation_factor_col = NULL,
  group_cols = NULL,
  output_col = "baseline_emissions_tco2e",
  gwp_ch4 = 28
)

Arguments

data

Tibble containing baseline waste characterisation data.

waste_quantity_col

Column storing the quantity of waste subject to the project activity (tonnes).

doc_fraction_col

Column storing the degradable organic carbon fraction (tonne C per tonne of waste).

docf_col

Column storing the fraction of DOC that degrades.

methane_correction_factor_col

Column storing the baseline methane correction factor (dimensionless).

methane_fraction

Methane fraction of landfill gas.

oxidation_factor_col

Optional column storing the oxidation factor.

group_cols

Optional character vector specifying grouping columns.

output_col

Name of the output column containing baseline emissions in tCO2e.

gwp_ch4

Global warming potential of methane.

Value

Tibble containing grouped baseline methane emissions in tCO2e.
