Data wrangling for the "IEA Net Zero by 2050" Roadmap

Scope and aim

This repository contains scripts and notebooks to transform the data supporting the IEA's Net Zero by 2050 flagship report (published May 2021) to the IAMC format.

Input data

Please download the data files from the IEA Net Zero by 2050 data page
and save them in the data folder of the cloned or downloaded repository.

Output data

The scripts and notebooks in this repository extract the data from the Excel spreadsheets of the Annex and each chapter's figures and tables and transform it to the format established by the Integrated Assessment Modeling Consortium (IAMC) and used in recent reports of the Intergovernmental Panel on Climate Change (IPCC) as well as several EU Horizon 2020 projects.

Dependencies

The Python package pyam was developed to facilitate working with timeseries data following the data format developed by the IAMC. Features include validation of values, aggregation and downscaling of data, and import/export (i/o) with various file formats (xlsx, csv, ...) and table layouts (wide vs. long data).

Read the docs for more information!

TL;DR - Quick install

You can install pyam and all its dependencies via the Python Package Index (PyPI) and on Conda.
