Calculate baseline decentralized utility emissions

Equation (1) of AMS-II.H consolidates greenhouse gas emissions from decentralized utility generation. The helper multiplies baseline fuel use by emission factors and optionally reports specific energy consumption when useful output data are provided.

calculate_baseline_decentralized_emissions_iih(
  baseline_data,
  fuel_consumption_col = "baseline_fuel_use_gj",
  emission_factor_col = "baseline_emission_factor_tco2_per_gj",
  useful_output_col = "baseline_useful_output_gj",
  group_cols = NULL,
  output_col = "baseline_emissions_tco2e",
  specific_energy_col = "baseline_specific_energy_gj_per_gj"
)

Arguments

baseline_data

A tibble describing the decentralized baseline system.

fuel_consumption_col

Column storing baseline fuel use in GJ.

emission_factor_col

Column storing baseline emission factors in tCO2e/GJ.

useful_output_col

Optional column storing useful thermal output (GJ). Set to NULL to skip specific energy diagnostics.

group_cols

Optional character vector of grouping columns to retain in the result.

output_col

Name of the emissions column to create.

specific_energy_col

Name of the specific energy column created when useful_output_col is supplied.

Value

A tibble with grouped baseline emissions (tCO2e) and, when requested, specific energy consumption (GJ/GJ).

Examples

  line = c("Boiler_A", "Boiler_B"),
  baseline_fuel_use_gj = c(4200, 3150),
  baseline_emission_factor_tco2_per_gj = c(0.071, 0.071),
  baseline_useful_output_gj = c(3600, 2700)
)
