Add targets for CO2 emissions per unit production at the portfolio level, using the SDA approach

Description

This function calculates targets of CO2 emissions per unit production at the portfolio-level, otherwise referred to as "emissions factors". It uses the sectoral-decarbonization approach (SDA) to calculate these targets.

Usage

target_sda(
  data,
  abcd,
  co2_intensity_scenario,
  use_credit_limit = FALSE,
  by_company = FALSE,
  region_isos = r2dii.data::region_isos,
  ald = deprecated()
)

Arguments

data	A dataframe like the output of r2dii.match::prioritize().
abcd	An asset-level data frame like r2dii.data::abcd_demo.
co2_intensity_scenario	A scenario data frame like r2dii.data::co2_intensity_scenario_demo.
use_credit_limit	Logical vector of length 1. FALSE defaults to using the column loan_size_outstanding. Set to TRUE to instead use the column loan_size_credit_limit.
by_company	Logical vector of length 1. FALSE defaults to outputting weighted_production_value at the portfolio-level. Set to TRUE to output weighted_production_value at the company-level.
region_isos	A data frame like r2dii.data::region_isos (default).
ald	ald has been superseded by abcd.

Value

A tibble including the summarized columns emission_factor_metric and emission_factor_value. If by_company = TRUE, the output will also have the column name_abcd.

Handling grouped data

This function ignores existing groups and outputs ungrouped data.

Examples

installed <- requireNamespace("r2dii.match", quietly = TRUE) &&
  requireNamespace("r2dii.data", quietly = TRUE) &&
  packageVersion("r2dii.match") >= "0.1.0"

if (installed) {
  library(r2dii.match)
  library(r2dii.data)

  loanbook <- head(loanbook_demo, 150)
  abcd <- head(abcd_demo, 100)

  matched <- loanbook %>%
    match_name(abcd) %>%
    prioritize()

  # Calculate targets at portfolio level
  matched %>%
    target_sda(
      abcd = abcd,
      co2_intensity_scenario = co2_intensity_scenario_demo,
      region_isos = region_isos_demo
    )

  # Calculate targets at company level
  matched %>%
    target_sda(
      abcd = abcd,
      co2_intensity_scenario = co2_intensity_scenario_demo,
      region_isos = region_isos_demo,
      by_company = TRUE
    )
}
