In r2dii.analysis: Measure Climate Scenario Alignment of Corporate Loans

r2dii.analysis

These tools help you to assess if a financial portfolio aligns with climate goals. They summarize key metrics attributed to the portfolio (e.g. production, emission factors), and calculate targets based on climate scenarios. They implement in R the last step of the free software ‘PACTA’ (Paris Agreement Capital Transition Assessment; https://www.transitionmonitor.com/). Financial institutions use ‘PACTA’ to study how their capital allocation impacts the climate.

Installation

Install the released version of r2dii.analysis from CRAN with:

install.packages("r2dii.analysis")

Or install the development version of r2dii.analysis from GitHub with:

# install.packages("pak")
pak::pak("RMI-PACTA/r2dii.analysis")

Example

• Use library() to attach the packages you need. r2dii.analysis does not depend on the packages r2dii.data and r2dii.match; but we suggest you install them – with install.packages(c("r2dii.data", "r2dii.match")) – so you can reproduce our examples.

library(r2dii.data)
library(r2dii.match)
library(r2dii.analysis)

• Use r2dii.match::match_name() to identify matches between your loanbook and the asset level data.

matched <- match_name(loanbook_demo, abcd_demo) %>%
  prioritize()

Add Scenario Targets

• Use target_sda() to calculate SDA targets of CO2 emissions.

matched %>%
  target_sda(
    abcd = abcd_demo,
    co2_intensity_scenario = co2_intensity_scenario_demo,
    region_isos = region_isos_demo
  )
#> Warning: Removing rows in abcd where `emission_factor` is NA

• Use target_market_share to calculate market-share scenario targets at the portfolio level:

matched %>%
  target_market_share(
    abcd = abcd_demo,
    scenario = scenario_demo_2020,
    region_isos = region_isos_demo
  )

• Or at the company level:

matched %>%
  target_market_share(
    abcd = abcd_demo,
    scenario = scenario_demo_2020,
    region_isos = region_isos_demo,
    by_company = TRUE
  )
#> Warning: You've supplied `by_company = TRUE` and `weight_production = TRUE`.
#> This will result in company-level results, weighted by the portfolio
#> loan size, which is rarely useful. Did you mean to set one of these
#> arguments to `FALSE`?
