MApper
Unified LCA · DSM/MFA · pLCA · AESA for environmental sustainability
The first desktop application that integrates Life Cycle Assessment, Dynamic Stock Modeling, prospective LCA, and Absolute Environmental Sustainability Assessment in a single workflow. Built for researchers who need system-level, time-resolved environmental impact analysis against planetary boundaries.
Four methods, one environment.
Every tool a life-cycle researcher needs: integrated so your models, data, and results stay coherent across methods.
LCA Engine
Full brightway2 integration with ecoinvent. Multi-method LCIA with contribution analysis, treemaps, and Sankey diagrams.
Stock Modeller
Cohort-based Dynamic Stock Modeling with Weibull survival functions. Tracks product populations — stocks, inflows, outflows — over time. Full Material Flow Analysis integration planned.
Coupled Subsystems
Model interconnected product populations within a single system. Primary subsystems drive dependent ones through configurable rules — charging infrastructure scales with BEVs, hydrogen stations with FCEVs, petrol stations decline with ICE phase-out. All impacts flow into Impact Assessment and AESA.
Prospective LCA
premise-powered scenario generation. Year-matched background databases for time-resolved impact assessment.
AESA
Four integrated methodologies — LCA, DSM/MFA, prospective LCA, and AESA — working together in a single unified workflow.
Archetype System
Hierarchical Bills of Materials with ecoinvent linking, scaling factors, and material evolution modeling.
Parametric Modeling
Define named parameters (e.g. battery_mass_lfp = 250) and reference them in BOM expressions. Build parameter sets for scenario comparison — Base vs Optimistic — and re-run the full pipeline to compare outcomes. Safe expression evaluation with arithmetic and built-in functions.
Foreground Evolution
Model technological change in your foreground system through learning rates, milestone-based shifts, and rebound effects in the use phase. Track how material efficiency and consumption patterns evolve over time.
From databases to planetary boundaries in three stages.
Import
Import ecoinvent databases, define archetypes with linked BOMs.
Model
Run DSM simulations, set technological learning rates, generate prospective databases.
Assess
Calculate impacts across manufacturing, operation, and end-of-life. Compare against planetary boundaries.
Open methodology.Reproducible results.PhD-grade rigor.
MApper is designed for system-level assessments. Methods are transparent and auditable. Results are reproducible. Compatible with ecoinvent cut-off, consequential, and APOS system models. If it holds up in your dissertation, it holds up everywhere.
