Regionalised Life Cycle Assessment with the Brightway2 Software – 2019
An introduction to the use of the Brightway2 Open Source LCA software with a particular focus on applying it to regionalised assessments. The matrix foundations of LCA and its use for uncertainty analysis. Creating and using regionalized activity datasets and regionalised impact assessment methods in Brightway2, with applications to a case study.
Day 1, morning: Brightway structure and first LCA
Introduction to the mental and computational model behind Brightway from the ground up. First applications of database creation, modification of datasets, and LCA calculations.
Day 1, afternoon: Uncertainty, sensitivity, and dynamic LCA
The matrix foundations of LCA, and how this is implemented in Brightway. How to apply matrix fundamentals for uncertainty analysis through Monte Carlo uncertainty assessment, including going beyond sampling from independent probability distributions. Using sensitivity analysis to find the key drivers of uncertainty. Dynamic LCA (LCA resolved in time) requires a completely different approach – graph traversal instead of matrix math.
Day 2, morning: Theory and methods for regionalization
How to regionalize inventory datasets. How to build and use regionalized impact assessment methods. Regionalization needs different matrices than site-generic LCA, and there are multiple options available for matrix-based methods. Review of matching spatial scales using raster and vector weighted averages.
Day 2, afternoon: Regionalized calculations
Application of regionalized methods to case studies. Combining regionalization with uncertainty assessment and dynamic LCA.
