r2dii.analysis is an R package that provides tools to calculate climate targets for financial portfolios. The version 0.0.1 is the first one released on CRAN.

You can install it from CRAN with:

install.packages("r2dii.analysis")

Then use it with:

library(r2dii.analysis)

The best place to know about this package is on its website. The home page details how to install and use this package, and includes a number of useful links – to try r2dii.analysis before you install it, to minimize installation errors, and to report bugs or raise issues. The navigation bar includes three important sections: (1) Get started introduces you to the package; (2) Reference lists every feature and links to its help file; and (3) Articles explains the Sectoral Decarbonization Approach (SDA), and the Market Share Approach.

As a preview, this snippet shows one feature of r2dii.analysis:

• Before you can use r2dii.analysis you need to load and prepare your data. Here I use toy data from the package r2dii.data, and two functions from the package r2dii.match.

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

# Using the package r2dii.data to imitate loading data
loanbook <- loanbook_demo
ald <- ald_demo
co2 <- co2_intensity_scenario_demo

# Using the package r2dii.match to prepare the data
matched <- match_name(loanbook, ald) %>% prioritize()

• You can now use r2dii.analysis, for example, to calculate targets of CO2 emissions per unit production at the portfolio-level – using the sectoral-decarbonization approach (SDA).

matched %>% target_sda(ald = ald, co2_intensity_scenario = co2)
