pbaesa is a python package for planetary-boundary-based absolute environmental sustainability assessment of anthropogenic systems.

## 🌍 Features

pbaesa enables:

1) The assessment of system-specific impacts on all global planetary boundary categories except novel entities by integration new life cycle impact assessment methods into the [Brightway LCA framework](https://docs.brightway.dev/en/latest).
2) The calculation of system-specific sustainability thresholds from time-explicit multi-regional input-output tables.

## ⚙️ Installation

You can install _pbaesa_ via [pip] from [PyPI]:

```console
$ pip install pbaesa
```

## 🚀 Usage

### Basic Example

```python
import bw2data as bd
import pbaesa
from pbaesa import utils

# Set your Brightway project
bd.projects.set_current('your_project_name')

# Load your biosphere database
bio = bd.Database("ecoinvent-3.10.1-biosphere")

# Create all planetary boundary LCIA methods
pbaesa.create_pbaesa_methods(biosphere_db=bio)

# Get allocation factors for a specific sector and location
allocation_factors = pbaesa.get_all_allocation_factor(
    geographical_scope="DE",  
    sector="Cultivation of wheat",
    year=2022
)

# Calculate a multi-LCA using Brightway to obtain mlca_scores

# Calculate exploitation of global safe operating space 
utils.calculate_exploitation_of_SOS(mlca_scores)

# Plot exploitation of global safe operating space against allocation factors
utils.plot_AESA(exploitations, allocation_factor_total_FCE, allocation_factor_total_GVA)

```

### Key Functions

- **`create_pbaesa_methods(biosphere_db, process_ids=[])`**: Creates and registers LCIA methods for all global planetary boundary categories except novel entities (climate change, ocean acidification, biosphere integrity, phosphorus cycle, atmospheric aerosol loading, freshwater use, stratospheric ozone depletion, land-system change, and nitrogen cycle).

- **`get_all_allocation_factor(geographical_scope, sector, year)`**: Retrieves allocation factors for a specific sector and geographical scope. If the allocation factors file is not present, the function will generate it automatically.

For a more detailed example, see the `examples/` directory.
