Correspondence table between UNFCCC CRF and EXIOBASE industry sectors

This repository contains a correspondence table (CT) that maps the UNFCCC Common Reporting Format (CRF) to the EXIOBASE v3 industry classification. The CT was compiled for our study on "Estimating the uncertainty of the greenhouse gas emission accountsin Global Multi-Regional Input-Output analysis" submitted to the Journal of Earth System Science Data (ESSD): https://essd.copernicus.org/preprints/essd-2023-473/

In the UNFCCC CRF (2019 revision) emission sources are grouped in categories and classifications, in a hierarchical order. The highest ranked categories - also called sectors - are 1) Energy, 2) Industrial Processes and Product Use, 3) Agriculture, 4) Land use, land-use change, and forestry (LULUCF), 5) Waste and 6) Other. Those sectors are further broken down into sub-categories, e.g. 1.A.1.a.i. The sub-categories of the sectors Energy, Agriculture and LULUCF are further broken down by the classification. The classification distinguishes different fuel types (in case of emission from "Energy') and animal types (in case of emissions from "Agriculture"). Like the categories, the classification also follows a hierarchical structure.

Parties report their emissions to the UNFCCC at different levels of resolution depending on national characteristics and data availability. 

Here, we provide two tables: 

correspondence_CRFdetailed_to_EXIOBASE_root.xlsx: Lists the correspondences only for the most detailed level (with regard to both category and classfication).

correspondence_CRFdetailed_to_EXIOBASE_coherent.xlsx: List the correspondences for all levels (automatically compiled from the 'root' table).

Collaboration in checking, revising and refining the correspondence table is appreciated. Please contact me if you have a revised version so that I can upload it to this repository.
