Work with multiregional input-output tables

Methods on prevention of double-counting and constructing characterization factors were taken from:

Work with MRIO data

This R-package provides various methods for environmentally-extended multi-regional input–output (EE-MRIO) analysis. It offers different methods for calculating EEMRIO matrices and includes a set of diverse characterization factors.

• supports EXIOBASE3 and Eora
• characterization factors:
  • biodiversity loss "bl" (currently only for Exiobase)
  • blue water consumption "bw"
  • climate change impacts "cc"
  • energy demand "en"
  • land use "lu"
  • material footprint "mf"
  • water stress "ws" (currently only for Exiobase)
• calculate:
  • production to demand matrix "pd"
  • production to target demand matrix "no-double-pt"
  • target to final supply matrix "no-double-ts"
  • target to final demand matrix "no-double-td"
  • production to final demand matrix "no-double-pd"
• create country dyads

First Steps

1 Install MRIO-Package

install.packages("remotes")
remotes::install_github("dvp17/mrio")

2 Calculate Matrix

Before you begin, set your working directory to the path where you store your Eora and Exiobase files:

e.g. setwd("C:/Data/Exiobase") or setwd("C:/Data/Eora")

setwd("C:/Data/Exiobase")
exio_cc <- mrio::exioloop(1995:2000, "cc", "pd")
utils::View(exio_cc[1:100,])

Please be aware that the process of calculating the matrices will take some time.

3 Create Dyads

setwd("C:/Data/Exiobase")
exio_cc_dyad <- mrio::dyads(1995:1996, exio_cc)
utils::View(exio_cc_dyad[1:100,])

Attention: The construction of dyads can be time-consuming. Please notice that no progress bar or estimated time for process completion is given before.

4 Look Into Characterization Factors

For additional information on which extensions are included for which environmental impact, have a look on the characterization factors listed in the package. Notice that calculation of water stress and biodiversity loss is a little more complex, which makes it difficult to provide a simple list on those CFs.

utils::View(mrio::cf_eora)
utils::View(mrio::cf_eora[mrio::cf_eora$cf_cc > 0,])

Recent Advancements

• added processing of pxp-matrices for EXIOBASE3

Plan

• add WIOD data
• add bl and ws for Eora
• add bl for pxp-matrices
• include social indicators
• structural path calculation?
• implement function to download data automatically
