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.
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("devtools")
devtools::install_github("RMI-PACTA/r2dii.analysis")
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)
r2dii.match::match_name()
to identify matches between your
loanbook and the asset level data.matched <- match_name(loanbook_demo, abcd_demo) %>%

target_sda()
to calculate SDA targets of CO2 emissions.matched %>%

The target_*()
functions provide shortcuts for common operations. They
wrap some utility functions that you may also use directly:
join_abcd_scenario()
to join a matched dataset to the relevant
scenario data, and to pick assets in the relevant regions.loanbook_joined_to_abcd_scenario <- matched %>%
join_abcd_scenario(
abcd = abcd_demo,
scenario = scenario_demo_2020,
region_isos = region_isos_demo
