A toolkit for exhaustively modeling the environmental impact of digital services.
The current perimeter is the carbon footprint associated with the fabrication and usage of servers, storage, network (usage only) and end user devices necessary for the existence of a digital service. Other environmental impacts (water, rare earth metals, etc.) will be added soon through an integration with the Boavizta API, and the lifecycle phases of device transportation and end of life are currently considered negligible.
You can explore the model’s didactic interface at this link. This interface allows for a limited use of the model (only one user journey on a single service when the code allows for an unlimited amount of objects) but is useful to discover the inputs and explore the calculation graphs (see below).
pip install efootprint
You can then run the quickstart script to familiarize yourself with the object logic and generate an object relationship graph and a calculation graph as html files in the current folder.
Check out INSTALL.md.
The code has been architectured to separate modeling from optimization from API logic. The goal is to make contribution to the modeling logic as straightforward as possible.
- Scripts that deal with modeling logic are located in efootprint/core.
- Optimizations (having the model rerun the right calculations whenever an input attribute or a link between objects changes) are dealt with in efootprint/abstract_modeling_classes.
- The API doesn’t exist yet but will be also decoupled from the modeling and optimization logics.
