Lifecycle: stable CRAN status Codecov test coverage R-CMD-check

These tools implement in R a fundamental part of the software PACTA (Paris Agreement Capital Transition Assessment), which is a free tool that calculates the alignment between financial portfolios and climate scenarios (https://www.transitionmonitor.com/). Financial institutions use PACTA to study how their capital allocation impacts the climate. This package matches data from financial portfolios to asset level data from market-intelligence databases (e.g. power plant capacities, emission factors, etc.). This is the first step to assess if a financial portfolio aligns with climate goals.

Installation

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

# install.packages("r2dii.match")

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

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

Example

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

Matching is achieved in two main steps:

1. Run fuzzy matching

match_name() will extract all unique counterparty names from the columns: direct_loantaker, ultimate_parent or intermediate_parent* and run fuzzy matching against all company names in the abcd:

match_result <- match_name(loanbook_demo, abcd_demo)
match_result 
#> # A tibble: 326 × 22
#>    id_loan id_direct_loantaker name_direct_loantaker       id_ultimate_parent
#>    <chr>   <chr>               <chr>                       <chr>

2. Prioritize validated matches

The user should then manually validate the output of [match_name()], ensuring that the value of the column score is equal to 1 for perfect matches only.

Once validated, the prioritize() function, will choose only the valid matches, prioritizing (by default) direct_loantaker matches over ultimate_parent matches:

prioritize(match_result)
#> # A tibble: 177 × 22
#>    id_loan id_direct_loantaker name_direct_loantaker          id_ultimate_parent
#>    <chr>   <chr>               <chr>                          <chr>

The result is a dataset with identical columns to the input loanbook, and added columns bridging all matched loans to their abcd counterpart.
