Known projects

Brightway2
Python Conda

Brightway2 is an open source framework for life cycle assessment (LCA). It doesn’t try to replace software like SimaPro or OpenLCA, but rather to offer new possibilities to those who want to break the limits of conventional LCA.

Activity Browser
Python Conda Brightway2 GUI

The activity browser is an open source software for Life Cycle Assessment (LCA) that builds on top of the Brightway2 LCA framework.

Premise
Python Brightway Ecoinvent IAM

Premise allows users to integrate user-made scenarios in addition (or not) to an IAM scenario. This is useful for example when a user wants to integrate projections for a sector, product or a technology that is not really covered by IAM scenarios.

Wurst
Python Brightway Ecoinvent

Wurst is a python package for linking and modifying industrial ecology models, with a focus on sparse matrices in life cycle assessment. Current development focuses on modifying the ecoinvent LCI database with scenario data from various data sources, using Brightway2 as the data backend.

carculator
Python prospective LCA REMIND Brightway

Prospective environmental and economic life cycle assessment of vehicles made blazing fast. carculator is a fully parameterized Python model developed by the Technology Assessment group of the Paul Scherrer Institut to perform life cycle assessments (LCA) of passenger cars and light-duty vehicles.

Lcopt
Python parametrised LCA Brightway

Lcopt is a python module for creating fully parameterised LCA foreground models using a Flask based interactive GUI developed by James Joyce. It integrates directly with BrightWay2, and can export models to SimaPro.

lca-algebraic
Python parametric inventories Brightway

This library is a small layer above brightway2, designed for the definition of parametric inventories with fast computation of LCA impacts, suitable for monte-carlo analyis.

bw2regional
Python regionalized LCA Brightway

bw2regional is a separate library that extends the Brightway LCA framework to do regionalized LCA calculations. It is easy to do regionalized LCA incorrectly. This package tries to make it at least a bit easier to do regionalization correctly, for at least some definitions of correct.

bw2_aware
Python regionalized LCA Brightway

This package provides the AWARE regionalized LCIA method in brightway and brightway2-regional. Monthly characterization factors are currently not imported.

pylcaio
Python hybridization Brightway

An object class to hybridize lifecycle assessment (LCA) and environmentally extended input-output (EEIO) databases.
