How-to

This repo contains all the scripts and data to reproduce the results of the paper, providing you have a valid EcoInvent licence. The impact model could not be shared in this repo as it contains calculated data from EcoInvent with licensing rights. Therefore, you must first build the impact model using Appa Build.

Install

git clone https://github.com/appalca/sustech_2026_ecoflow_resources.git
cd sustech sustech_2026_ecoflow_resources
pip install -r requirements.txt

Build the impact model

In order to build the impact model, you will need to use Appa Build. Please follow the installation instructions here: https://appalca.github.io/basics/getting_started.html.

To familiarize yourself with Appa Build, it is recommended to take a look at the doc: https://appalca.github.io/basics/appa_build_basics.html.

To build the impact model, make sure you exported first the environmental variables BW_USER and BW_PASS with your EcoInvent credentials. Then, run, while being at the root this repository:

appabuild lca build data/conf/appalca.yaml data/conf/run_SoC.yaml

Then set the build impact model (SoC.yaml) in the data/ folder.

Carbon-only impact model

A carbon-only version of this impact model, using only public data sources, is currently under construction, and will be shared in this repository when available for those who don't have an EcoInvent license.

Run the scripts

You can then run any of the python script placed in the root of this repository to produce the corresponding figure or table.
