The Activity Browser (AB) is an open source software for Life Cycle Assessment (LCA) that builds on Brightway2.
Video tutorials are available on youtube.
Please also read and cite our scientific paper.
You can install and start the activity-browser like this:
conda create -n ab -c conda-forge --solver libmamba activity-browser conda activate ab activity-browser
You can also install the AB using Mamba:
mamba create -n ab activity-browser mamba activate ab activity-browser
We recommend that you use conda to manage your python installation. You can install Anaconda or the more compact miniconda (Python 3 version) for your operating system. Installation instructions for miniconda can be found here. See also the conda user guide or the Conda cheat sheet.
Skip this step if you already have a working installation of anaconda or miniconda, but make sure to keep your conda installation up-to-date:
conda update -n base conda.
The activity-browser has many dependencies that are managed by the conda-forge channel. Open a cmd-window or terminal (in Windows you may have to use the Anaconda prompt) and type the following:
conda config --prepend channels conda-forge
Also configure conda to use the libmamba solver which is significantly faster than the default.
conda config --set solver libmamba
conda create -n ab -c conda-forge activity-browser conda activate ab activity-browser
At this point the activity-browser and all of its dependencies will be installed in a new conda environment called
ab. You can change the environment name
ab to whatever suits you.
We recommend to regularly update the AB to receive new features & bugfixes. These commands will update the activity-browser and all of its dependencies in the conda environment called
conda activate ab conda update activity-browser
First activate the environment where the activity browser is installed:
conda activate ab
Then simply run
activity-browser and the application will open.
Project-tab there is initially a button called "Add default data (biosphere flows and impact categories)". Click this button to add the default data. This is equivalent to
|Plugins are not necessarily developed by Activity Browser maintainers. Below are listed plugins from people we trust but we do not check plugins code. Use them at your own risk.|
|The plugin system is still in development so keep in mind that things may change at any point.|
2.8 release a plugin system has been added to the AB. Plugins are a flexible way to add new functionalities to the AB without modifying the software itself.
The plugin code has been designed and written by Remy le Calloch (supported by G-SCOP laboratories) with revisions from the AB-team.
These are the plugins that we know about. To add your plugin to this list either open an issue, or a pull request. All submitted plugins will be reviewed, although all risks associated with their use shall be born by the user.

Every plugin's Github page (links are provided in the above table) should have a Get this plugin section with installation instructions.
Plugins are conda packages (like the Activity Browser). To add a plugin simply install it in your conda environment from the Anaconda repos.
-c conda-forge to the install command like below to avoid problems with dependencies.
conda activate ab conda install -c pan6ora -c conda-forge ab-plugin-notebook
Once a new plugin is installed restart the Activity Browser.
Plugins are enabled per-project. Simply open the plugin manager in the
Tools > Plugins menu.
Close the plugin manager. New tabs should have appeared in the AB (each plugin can spawn one tab on each left/right panel).
Disable a plugin the same way you activated it.
⚠️ Keep in mind that all data created by the plugin in a project could be erased when you disable it.
The best place to start to create new plugins is the plugin template. Its code and README will help you to understand how to create a plugin.
